Selection Guide

Silicone & Specialty Chemical Grade Selection Guides | SEMITECH

Deterministic grade-selection guides for MESIL silicone fluids, emulsions, and GMATT matting agents. Match viscosity, Si-H content, active solids, and substrate to the right product — fast.

Stop Guessing. Select the Right Grade First Time.

Each guide in this library gives you a decision framework — viscosity ranges, crosslink density targets, substrate compatibility, and process constraints — so you can shortlist the correct SEMITECH grade before testing begins.

What's Covered

  • Hydrogen silicone fluids — Si-H content 0.18 %–1.58 %, reactive cross-linking applications
  • Hydrogen-terminated silicone oils — THF grade matching by chain-end Si-H density
  • Vinyl silicone fluids — viscosity 20–20,000 cSt, terminal vinyl content for HTV/LSR
  • MESIL 107 OH polymers — 750–550,000 mm²/s kinematic viscosity, curing speed vs. strength
  • Textile amino silicone emulsions — substrate × hand feel × padding vs. exhaust process
  • Water-based PDMS emulsions (MESIL BS) — active solids ~50 %, non-ionic, solvent-free
  • Coating matting agents — GMATT & HMMAT grade selection by gloss target, PVC, and DFT

How to Use These Guides

Each guide is structured as a decision matrix: start with your process constraint (viscosity, active content, substrate) and the guide walks you to the matching grade. Where alternatives exist, trade-offs are stated explicitly.
