Application scenario preferred type Key indicators Typical brand examples
Release agent 350 cSt PDMS surface tension<22 mN · m ⁻¹ DM-350
LED packaging phenyl silicone resin refractive index 1.53 OE-6550
Thermal paste 1000 cSt dimethyl silicone oil+Al ₂ O ∝ thermal conductivity 2.0 W · m ⁻¹· K ⁻¹ TC-1000
Textile finishing side chain epoxy silicone oil epoxy equivalent 0.20 E-soft 2025
Three step filtering logic
Step 1: First determine the "physical properties" - temperature range, polarity, mechanical strength;
Step 2: Redefine "chemistry" - whether reactivity (hydroxyl, vinyl, epoxy) is required;
Step 3: Finally determine the "process" - viscosity, curing method, compatibility.

conclusion
Translating complex chemical language into "parameter coordinates" can make silicone oil/resin selection as simple as looking up a dictionary. May this cheat sheet become your 'cheat sheet' on the experimental platform.
