Chemical Name: Vinyl-Terminated T-Structured Polydimethylsiloxane
Ingredient Information
Dimethylvinyl-Terminated T-structured Polydimethylsiloxane
CAS NO: 126581-51-9
Chemical Structural Formula
Product Overview
IOTA 22713 is a vinyl-terminated T-structured polydimethylsiloxane, containing one inert small molecular functional group and three vinyl-terminated polydimethylsiloxane chain segments. It can crosslink with components containing Si-H and is also highly compatible with polysiloxanes containing vinyl functional groups. T-shaped polysiloxane helps reduce the viscosity of silicone composites during processing or organosilicon products, regulates the hardness, modulus, and elongation at break of silicone materials, and is beneficial for improving the flowability of thermal interface materials.

Application
This product is a vinyl-terminated T-structured polydimethyloxane, with high reactivity during silicon hydroaddition. It is highly compatible with various vinyl-containing silicone oils, helps reduce viscosity during silicone composite processing or silicone products, adjusts the hardness, modulus, and elongation at break of silicone materials, and improves the flowability of thermal interface materials.
Storage and Packaging
1. 1kg, 5kg, 25kg, and 200kg inner coated iron drum or ton-ton drum packaging, sealed with nitrogen charge.
2. Store in a cool, dry place, avoid contact with strong oxidizers, acids, and alkalis, and keep away from heat sources.
3. Shelf life is 3 months; after the expiration date, it can be re-inspected according to standards and can still be used if it meets standards.
Safety
It is non-flammable and not a hazardous material.
