In the silk/satin anti-slip addition-cure LSR spectrum, the "micro-Pt A (2:100) with mid-high-visc B (60k) yielding 56,000cps@23℃ scrape viscosity" and "Pt-locked-in-A + vinyl/SiH B addition network" jointly dictate capillary self-wick into 8-10μm silk fibrils, fast heat-cure efficiency at 125℃ class, and adhesion/non-stiffening boundary on silk-protein substrate. Plain 1:1 LOGO ink (3M35, 86k) too thick smothers silk grain; lace 3M40-45 (76k/30A) too soft/perforation-oriented; satin smooth surface needs harder grip support; condensate RTV releases alcohol stiffens and yellows non-food-grade. As silk scarf grip dots, satin tablecloth anti-slip strips, mulberry silk garment lining grip, and high-end home-textile satin scrape demand "2-part A:B 2:100, A 300cps/B 60k/blend 56k, transparent, Shore A 40, 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 mid-visc silk-wick domestic product has become the core gap for silk-grip glue localization. Addressing this "silk-wick fullness" pain point, Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches Silk-Type Anti-Slip Addition LSR IOTA LSR 3M40-43 (2-part Pt-cured methylvinyl polysiloxane, A transparent 300cps with Pt / B transparent 60,000cps). Characterized by "pre-cure A:B 2:100 (wt), A 300mPa·s/B 60,000mPa·s, blend 56,000mPa·s(23℃ stirred), 25℃ pot-life ~1h; post-cure transparent, Shore A 40, 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 + 56k mid-visc silk-wick + 40A/300% hard-elastic grip," it serves as the "silk anchor" for silk-scarf/satin scrape/home-textile grip. Molecular Architecture: Micro-Pt Locked A + 56k Silk-Wick Self-Flow + 40A/300% Hard-Elastic Grip 3D Logic The core competitiveness of IOTA LSR 3M40-43 stems from its "Part A: vinyl polysiloxane + trace Pt catalyst (Karstedt, locked in A, 2 parts); Part B: SiH polysiloxane crosslinker + fumed silica/silk-protein 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 ensures 125℃ few-min full cure yet avoids 1:1 Pt overload causing thin silk yellowing and thick-layer center overheating; A small drum (2kg) lowers Pt cross-contamination risk, B big drum (200kg) main-line economical.
  • 56k Silk-Wick Self-Flow： Blend 56k mPa·s (23℃ stirred) is "mid-visc silk-wick grade"—thinner than lace 3M40-45 (76k), far thinner than LOGO 3M35 (86k), scrapes satin surface wicking into 8-10μm fibril gaps forming silk-gum interpenetration without thick surface film; after degas scrape bubble-free, cured silk grain transparent, grip dots full not flat.
  • 40A/300% Hard-Elastic Grip： Shore A 40 one notch harder than lace 30A, one notch softer than general screen ink 45-50A—"satin grip sweet-spot"; tensile ≥6MPa + elong ≥300% + tear ≥15kN/m, cure layer folds with scarf no grain-fall no blush, surface micro-rough gives static grip, scarf on shoulder/neck no slip, 50 washes no dot loss; food-grade base makes neck-contact harmless, passes FDA/LFGB class.
Performance Leap: From "1:1 Ink Smothers Silk Grain" to "2:100 56k Silk-Wick Grip" Incorporating IOTA LSR 3M40-43 enables qualitative leaps:
  • Silk Scarf Grip： Large square scarf shoulder dot-matrix scrape, small square corner grip strip—125℃ few-min cure, silk grain clear not smothered by gum film, wear-friction no slip, dry-wash/wet-wash no dot loss.
  • Silk Home-Textile： Silk tablecloth edge grip, satin placemat scrape, mulberry pillowcase grip dots—good silk-protein adhesion no primer, no re-stiffen no yellow.
  • Premium Garment Lining： Silk shirt inner-collar grip, satin lingerie strap grip, silk robe belt grip—40A moderate no skin-poke, -20℃ fold no crack.
  • Other Scrape： Satin woven label, anti-fake scallop, fabric 3D transfer base.
Application Penetration: From Silk Scarf to Satin Pillowcase IOTA LSR 3M40-43 covers sectors triple-sensitive to "silk-wick self-flow + mid-hard grip + food-grade no-yellow":
  • Apparel Trim： Silk scarf grip dots, satin shirt inner-collar, lingerie strap grip, robe belt grip.
  • Home Textile： Silk tablecloth grip strip, satin placemat, mulberry pillowcase grip, satin curtain hem.
  • Shoe/Leather/Bag： Silk-fabric shoe upper grip, leather scallop scrape, satin-webbing bump.
  • Specialty Scrape： Satin 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); thin silk suggest low-temp short (e.g. 110℃×60-90s) avoid silk yellowing.
  • 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 silk grey cloth silk-gum/anti-soil/sulfide dye.
  • 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 silk apparel upgrading from "pure decor" to "grip + neck-contact food-grade", and export silk-home textiles mandating REACH/RoHS compliance, silk-dedicated LSR is upgrading from "Wacker Elastosil® LR screen-branch / Momentive Silopren® LSR import followers" to "2:100 micro-Pt mid-visc silk-wick reference glue." IOTA LSR 3M40-43, with its "A:B 2:100 + blend 56k + A 300/B 60k + Shore A 40 + elong ≥300% + tear ≥15kN/m + Pt-in-A + food-grade four certs + 12mo" hard metrics, fills the domestic supply chain gap for silk-type anti-slip addition LSR in scarf/home-textile/satin-lining grip fields, providing a mass-producible path to replace imported screen silicones for downstream silk-print/coating makers. This confirms domestic print LSR is advancing steadily along "condensate RTV (alcohol stiff yellow) → 1:1 LOGO ink 3M35 (smother silk) → 2:100 lace 3M40-45 (30A perforation) → 2:100 silk 3M40-43 (56k/40A silk-wick grip)," with growing technical say in silk anti-slip key print-glues.
