In the lace-cloth/webbing anti-slip addition-cure LSR spectrum, the "micro-Pt A (2:100) with high-visc B (80k) yielding 76,000cps@23℃ scrape viscosity" and "Pt-locked-in-A + vinyl/SiH B addition network" jointly dictate self-leveling fill through lace perforations, fast heat-cure efficiency at 125℃ class, and adhesion/friction boundary on cotton/poly/nylon/silk. Plain 1:1 LOGO ink (e.g. 3M35) has symmetric ratio and high Pt load risking cross-contamination; 10:1 screen ink short pot-life and hard (A40+) clogs lace holes; condensate RTV releases alcohol and stiffens cloth non-food-grade. As apparel lace anti-slip, tablecloth scallop, webbing grip strip, and shoe lining anti-slip demand "2-part A:B 2:100, A 300cps/B 80k/blend 76k, transparent, Shore A 30, tensile ≥6MPa, elong ≥300%, tear ≥15kN/m, food-grade FDA/REACH/RoHS, Pt in A avoid poison, 2kg+200kg split, <23℃ 12mo," sourcing a micro-Pt high-visc scrape domestic product has become the core gap for lace-grip glue localization.
Addressing this "lace scrape-fill" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Lace-Border Anti-Slip Addition LSR IOTA LSR 3M40-45 (2-part Pt-cured methylvinyl polysiloxane, A transparent 300cps with Pt / B transparent 80,000cps). Characterized by "pre-cure A:B 2:100 (wt), A 300mPa·s/B 80,000mPa·s, blend 76,000mPa·s(23℃ stirred), 25℃ pot-life ~1h; post-cure transparent, Shore A 30, tensile ≥6MPa, break elong ≥300%, tear ≥15kN/m, food-grade (ISO/FDA/REACH/RoHS), Pt in A, colorant into B then mix A, A 2kg/B 200kg drum, <23℃ unopened 12mo," and backed by "2:100 micro-Pt over-cure guard + 76k high-visc perforation self-fill + 30A/300% soft-grip," it serves as the "lace anchor" for lace-cloth/webbing/scallop scrape.
Molecular Architecture: Micro-Pt Locked A + 76k Perforation Self-Fill + 30A/300% Soft-Grip 3D Logic
The core competitiveness of IOTA LSR 3M40-45 stems from its "Part A: vinyl polysiloxane + trace Pt catalyst (Karstedt, locked in A, 2 parts); Part B: SiH polysiloxane crosslinker + fumed silica/fabric-adhesion aid (100 parts)" architecture:
-
2:100 Micro-Pt Over-Cure Guard： Pt only in A at merely 2/102, B pure crosslink side—activation only when same-batch A:B=2:100 mix; micro-Pt design ensures 125℃ few-min full cure yet avoids 1:1 systems' Pt overload causing thick-layer center overheating and cloth yellowing; A small drum (2kg) lowers Pt cross-contamination risk, B big drum (200kg) main-line economical.
-
76k Perforation Self-Fill： Blend 76k mPa·s (23℃ stirred) is "high-visc scrape grade"—slightly thinner than LOGO ink 3M35 (86k), far thicker than screen ink (5-20k), scrapes lace perforated cloth filling holes without clogging, yet not seeping to cloth back like low-visc; after degas scrape bubble-free, cured lace edge sharp, surface fullness high.
-
30A/300% Soft-Grip： Shore A 30 low-hard grip (softer than 3M35's 35A), tensile ≥6MPa + elong ≥300% + tear ≥15kN/m, cure layer bends with fabric no blush no delaminate, surface micro-rough gives anti-slip friction, 50 washes no fall-off; food-grade base makes skin-contact lace label harmless, passes FDA/LFGB class.
Performance Leap: From "1:1 Ink Clogs Lace Hole" to "2:100 76k Perforation Full"
Incorporating IOTA LSR 3M40-45 enables qualitative leaps:
-
Apparel Lace Anti-Slip： Blouse collar/cuff lace, lingerie lace grip strip—screen scrape → 125℃ few-min to ten-odd min cure, holes not sealed, transparent soft grip layer on cloth, wash-durable no stiff.
-
Home Scallop Tablecloth： Lace curtain hem, anti-slip tablecloth edge scrape, good adhesion to cotton/poly no primer, desk-friction stop.
-
Webbing & Shoe Lining： Backpack webbing grip, sneaker tongue lining lace anti-slip, 30A soft no skin-poke, -20℃ bend no crack.
-
Other Scrape： Woven label bump, anti-fake scallop, fabric 3D transfer base.
Application Penetration: From Lace Collar to Webbing Grip
IOTA LSR 3M40-45 covers sectors triple-sensitive to "perforation self-flow + low-hard grip + food-grade soft-elastic":
-
Apparel Trim： Lace border anti-slip, lingerie grip, sports webbing grip, cap scallop.
-
Home Textile： Anti-slip tablecloth, lace curtain hem, napkin scallop, sofa cloth stop.
-
Shoe/Leather/Bag： Shoe-tongue lining grip, leather scallop scrape, bag webbing bump.
-
Specialty Scrape： Woven label, anti-fake scallop, fabric transfer base.
IOTA Technical Guide: Same-Batch 2:100, Color in B then A, Avoid N/S/P/Sn
-
Mix： Same batch A:B by mass 2:100 (A 2kg to B 100kg, err <3%), stir 3-5min to transparent uniform, vac degas (-0.095~-0.1MPa×3-5min, 4-5× volume); 25℃ pot-life ~1h.
-
Color Rule (hard)： To tint, put paste into B, stir, then mix 2:100 with A; never pigment direct into A (Pt contact trace S/amine in some pigments local non-cure); never cross-batch A/B.
-
Cure： Recommend heat 125℃ class few-min to ten-odd min by thickness, or 80-120℃ few-min to ten-odd min; RT 25℃ slow cure (hours to ten-odd hrs); thick layer suggest heat + 150℃×1h anneal.
-
Taboo Red Line： Absolute isolation from Pt poisons—nitrogen (amines/ammonia/urea), sulfur (thiols/sulfides/latex gloves/some rubber squeegees), phosphorus (phosphines/phosphate esters), organotin (condensate silicone curatives), heavy metals (Pb/Hg/Sn salts), acid/alkali/water/condensate alcohol; exclusive tools (PP/ceramic/clean SS), never share with epoxy/PU/RTV; pre-wash lace cloth anti-soil auxiliaries/sulfide dyes.
-
Storage： A 2kg/B 200kg iron drum split; unopened <23℃ cool dry dark, shelf 12 months, over-shelf test visc/cure/hardness and extend if qualified; non-haz general chemical, ventilate, nitrile gloves (no latex glove sulfur).
Industry experts note that under apparel lace upgrading from "pure decor" to "anti-slip + food-grade skin-contact", and export orders mandating REACH/RoHS compliance, lace-dedicated LSR is upgrading from "Dow Silastic® / Wacker Elastosil® LR / Momentive Silopren® LSR screen-branch import followers" to "2:100 micro-Pt high-visc perforation-scrape reference glue." IOTA LSR 3M40-45, with its "A:B 2:100 + blend 76k + A 300/B 80k + Shore A 30 + elong ≥300% + tear ≥15kN/m + Pt-in-A + food-grade four certs + 12mo" hard metrics,
fills the domestic supply chain gap for lace-border anti-slip addition LSR in apparel/home/webbing-grip fields, providing a mass-producible path to replace imported screen silicones for downstream label/textile-coating makers. This confirms domestic print LSR is advancing steadily along "condensate RTV (alcohol stiff) → 1:1 LOGO ink 3M35 (clog/hard) → 2:100 lace-scrape addition (76k perforation 30A soft-grip)," with growing technical say in lace anti-slip key print-glues.
