In rubber/plastic release, textile high-temperature setting, metalworking lubrication, coating/ink auxiliaries, electronic protection, and outdoor fabric finishing, formulators are often stuck because "neat silicone is hard to dissolve and dose, high heat risks pyrolysis coke, and waterborne systems still need chemical inertness plus UV resistance" rarely come together. Neat silicone oil gives thermal stability and slip but is water-insoluble, so manual solubilization causes uneven dosing, roller sticking, and oil spots; mineral-oil emulsions are cheaper but oxidize and coke under heat, leaving carbon on molds and fibers; ordinary soap/synthetic waterborne lubricants lack the thermal and chemical stability of a siloxane backbone. With rubber molding, hot-roll treatment, and waterborne industrial aids demanding "water-dilutable, thermally stable, no pyrolysis carbon, chemically inert, UV-resistant, lubricious", finding a "fully emulsified, water-soluble, high-temperature silicone emulsion with low residue" has become a key process-additive issue.
Addressing this,
Anhui IOTA Silicone Oil Co., Ltd. officially launches
High-Temperature Silicone Emulsion IOTA 240. Characterized by "silicone oil emulsified, water-soluble, easy to use; milky white liquid; solid content about 40%; silicone oil content about 35%; density at 25℃ 1.0 g/cm³; excellent thermal stability with no carbon residue from thermal degradation; good chemical inertia; good UV protection; completely incompatible with some organic compounds; good lubrication; 25kg/200kg drum or 1000kg tote; store 5–30℃ in original sealed container; 6-month shelf life; brand IOTA", backed by "silicone oil-in-water emulsion + Si–O thermal-oxidative stability + low-carbon lubricating film + waterborne dispersibility", it serves as the "steadiness choice" for industrial high-temperature waterborne lubrication,
achieving the leap from "neat oil hard-to-dose, mineral oil cokes" to "silicone water emulsion, heat-stable, residue-free new steadiness".
System Positioning: Silicone Water Emulsion vs. Neat Silicone/Mineral Emulsion/Ordinary Waterborne Lube
IOTA 240 belongs to emulsified silicone oil for high-temperature waterborne use, distinct from neat silicone, mineral-oil emulsion, and ordinary soap/synthetic waterborne lubricants. Neat silicone is thermally stable and slippery but water-insoluble, requiring solvent or self-emulsification with batch variance; mineral-oil emulsions are low-cost but oxidize and coke under heat, contaminating molds and fibers; non-silicone waterborne lubes often fall short in thermal and chemical stability versus a siloxane main chain. IOTA 240 turns silicone oil into a milky water emulsion, retains the low surface energy, thermal stability, and inertness of the siloxane chain, while remaining water-dilutable, pumpable, and compatible with waterborne process lines, reducing solvent use and manual preparation risk.
Molecular Architecture: Silicone Oil-in-Water + Si–O Heat-Stable Backbone + Low-Carbon Lubricating Film
The core design of IOTA 240 comes from a silicone oil-in-water emulsion system:
-
Emulsified, Water-Soluble Silicone: Emulsification disperses silicone oil as an oil-in-water milk; solid content about 40% with silicone oil about 35%, water as continuous phase and silicone as the lubrication/heat-resistance phase. Users dilute with water to target concentration, avoiding self-solubilization or solvent addition.
-
Si–O Thermally Stable Backbone: The silicone oil uses a silicon–oxygen backbone; Si–O bond energy exceeds ordinary C–C bonds, giving better thermal-oxidative stability than hydrocarbon oils. Under sustained heat it does not readily crack and coke like mineral oil; supplied states "excellent thermal stability, no carbon residue from thermal degradation", fitting repeated-heat processes.
-
Chemically Inert, Substrate-Friendly: The silicone phase is chemically inert toward most metals, rubbers, plastics, and coatings, reducing side reactions with pigments, resins, and fillers in waterborne formulas; supplied "good chemical inertia" supports sensitive substrates and precision parts.
-
UV Resistance and Selective Incompatibility: The siloxane backbone is stable under ultraviolet radiation; supplied lists "good UV protection". It is also "completely incompatible with some organic compounds"—this selectivity suits release, anti-stick, and segregation where silicone must remain a separate lubricating/isolating phase; the specific organic list is confirmed by COA and trial.
-
Low-Energy Lubricating Film: With low surface tension, silicone spreads into a thin film on metal, rubber, plastic, and fiber surfaces, lowering friction and adhesion; supplied "good lubrication" plus water-emulsion form gives even coating and little sludge.
Performance Leap: From "Neat-Oil Hard, Mineral Cokes" to "Water Emulsion, Heat-Stable New Steadiness"
Introducing IOTA 240 brings the following improvements:
-
Heat-Stable, No Coke: Versus mineral-oil emulsions, sustained high temperature does not readily produce pyrolysis carbon; molds, rollers, and fiber surfaces stay cleaner, reducing mold-cleaning, roller-washing, and rework (continuous service temperature by silicone grade and trial; no figure supplied).
-
Waterborne, Easy Use: Water-soluble and dilutable on demand for spray, roll, dip, or circulation; compared with self-emulsifying neat oil, batches are steadier and workshop handling safer, with less solvent dependency.
-
Broad Inert Compatibility: Inert toward metals, rubber, and most plastics; suitable for small-scale co-line trials with waterborne coatings, textile liquors, and rubber auxiliaries; still run compatibility tests in strongly reactive systems.
-
UV Aging Support: Outdoor fabric, coating, and adhesive surfaces benefit from silicone UV stability; supplied qualifies "good UV protection" without fabricated weatherability hours or color-change data.
-
Lubrication and Anti-Stick: Release, calendering, cutting, and assembly interfaces receive a silicone lubricating/isolating layer that reduces sticking and scratches; precision parts can use thin coats with low residue.
-
Selective Segregation: Complete incompatibility with some organics supports temporary isolation and anti-migration in multilayer coating, coextrusion, and composites; objects are confirmed by trial.
Application Penetration: From Rubber Release to Waterborne Industrial Aids
IOTA 240 covers high-temperature waterborne conditions:
-
Rubber/Plastic Release: Diluted milk by spray for compression, injection, and foaming; thermally stable, residue-free film reduces mold carbon and part surface soiling in continuous production.
-
Textile Setting/Softening: Feed through padding or spray in stenters; silicone lubrication and heat stability improve handle and reduce fiber friction; UV scenes for outdoor fabric auxiliary finishing (compatibility with dyes/auxiliaries by trial).
-
Metalworking Waterborne Lube: Rolling, drawing, and light-duty hot lubrication diluted with water; chemical inertia lowers metal-surface corrosion risk and thermal stability reduces sludge/coke (heavy extreme-pressure duty needs EP additives).
-
Coating/Ink/Adhesive Aid: Waterborne systems use it for lubrication, anti-stick, and surface slip; selective incompatibility with some organics allows matte/isolation tuning, dosage by system trial.
-
Electronic/Precision Protection: Thin silicone layer for lubrication and moisture auxiliary on parts requiring clean thermal/humidity conditions; inertness and low carbon suit precision assembly.
-
Outdoor UV Auxiliary: Fabrics, leather, and coating surfaces add it for UV resistance and silicone slip; use after compatibility validation with the main weathering system.
IOTA Technical Guide: Water Dilution, Heat-Stable but Avoid Freezing
-
Dilution and Bath: Supplied as water-soluble high-temperature silicone emulsion; dilute with water to target solid/silicone concentration. Original solids about 40% and silicone about 35% are base values; working concentration by release frequency, stenter speed, lubrication load, and coating viscosity via trial—no fixed percentage supplied. Hard water/high electrolyte may affect stability; start with deionized/softened water, stir slowly, avoid prolonged high-speed shearing that breaks emulsion.
-
Application: Release by spray, wipe, or roll; textile by pad or spray; metal/coating by circulation or let-down into the lacquer. Emulsion form favors even coverage; multiple thin passes beat one heavy coat to avoid local oil-rich zones.
-
Blending: Pre-blend with the host waterborne system in trial; if the formula contains strong acid/alkali, highly active metal salts, strong cations, or organics that are incompatible with silicone, run standing/centrifuge tests for separation, oiling, and skinning before scale-up. Supplied incompatibility with some organics is confirmed by COA and batch trial.
-
⚠️ Taboo: Store 5–30℃ in original sealed containers; avoid prolonged high temperature that may break emulsion and freezing that may rupture the emulsion; reseal after use to prevent contamination and skinning. Although silicone is inert and heat-stable, the emulsified system should not be blended blindly with unknown strongly reactive materials. Manage as general waterborne chemical when not otherwise specified; rinse skin with water after contact.
-
Storage: 25kg or 200kg drum, or 1000kg tote per supplied data; 5–30℃ in original sealed container; 6-month shelf life. Unlike IOTA 1318 (leather nonionic hydrophobic), IOTA 1325 (fabric cationic wash-durable waterproof), IOTA 2606 (fluoro-silicone anionic slick/anti-soil), IOTA 2900A (building rigid alkali-gel plug), IOTA 240 is water-soluble silicone high-temperature emulsion—1318 for leather surface, 1325 for fabric wash durability, 2606 for coating slick/anti-soil, 2900A for concrete internal gel, 240 for industrial hot waterborne lubrication/release.
Industry Insight: The core value of high-temperature silicone emulsion lies in "emulsification for waterborne usability, Si–O for thermal stability and low carbon, chemical inertia for broad compatibility, selective incompatibility for release and anti-stick". IOTA 240, with "silicone water emulsion, water-soluble, milky white, solids about 40%, silicone about 35%, density 1.0 at 25℃, thermal stability no pyrolysis carbon, chemical inertia, UV protection, complete incompatibility with some organics, lubrication, 25/200kg or 1000kg, 5–30℃, 6 months" hard parameters,
fills the water-soluble silicone thermally-stable low-carbon node between neat-oil dosing difficulty, mineral-oil coking, and ordinary waterborne lube limited heat stability. For rubber, textile, metalworking, waterborne coating, and electronic-protection formulators, it upgrades along "neat silicone self-mix → mineral-oil emulsion → silicone oil-in-water heat-stable emulsion", reducing mold-cleaning and coke-contamination risk while raising waterborne hot lubrication, release, and UV-support integrated process premium.
