Vinyl Silicone Oil 50cst CAS 68083-19-2 Low Viscosity Divinyl PDMS for Silicone Ink Coating
50cst Vinyl Silicone Oil (CAS 68083-19-2) is divinyl-terminated polydimethylsiloxane (Divinyl PDMS). With low viscosity and high vinyl activity, it is specially designed for silicone ink and silicone coating systems. It possesses outstanding compatibility with silicone additives and crosslinkers. It optimizes fluidity of ink formula, promotes uniform film formation, and endows cured coating with flexibility, weather resistance and anti-stick property.
Product Overview
50cst Vinyl Silicone Oil (CAS 68083-19-2) is linear divinyl-terminated polydimethylsiloxane. The terminal vinyl groups enable hydrosilylation crosslinking reaction with hydrogen silicone oil under platinum catalyst. Low viscosity characteristic brings superior fluidity, making it an ideal base material for silicone ink and transparent silicone protective coatings. It can be mixed freely with various silicone auxiliaries to develop stable coating formulas.
Key Features
- Low viscosity, excellent liquidity and easy mixing
- Uniform vinyl content, stable crosslinking reactivity
- Great compatibility with hydrogen-containing silicone oil
- Improve leveling property and reduce surface defects of silicone ink
- Cured film has good flexibility, weather resistance and hydrophobicity
Main Applications
- Base polymer for addition cure silicone printing ink
- Raw material for transparent silicone protective coating
- Reactive modifier for thin-layer silicone coating
- Functional additive for surface anti-stain silicone coatings
Usage Guidance
Mix with methyl hydrogen silicone oil, platinum catalyst and fillers according to formulation requirements. Adjust proportion to control curing speed and coating hardness. Avoid contacting substances that may poison platinum catalyst, such as amines, tin compounds and heavy metals.
Storage & Package
Seal tightly and store in cool, dry and ventilated warehouse. Keep away from high temperature, ultraviolet light and oxidants. Standard package: 25kg plastic drum, 200kg iron drum. Shelf life: 12 months under proper storage.
