Vinyl-branched Polydimethyl Silicone Fluid

USi-OB4

DESCRIPTION
USi-OB4 is a fluid consists of pendant style vinyls on the silicone backbone. The molecular weight is independent of vinyl contents.

CHEMICAL FORMULA
(CH3)3SiO[(CH3)2Si]m[(CH2=CH)(CH3)SiO]nSi(CH3)3

FEATURES
Molecular weight as per the request of customer
Functions and features same as that of polydimethylsiloxane
Vinyl functionality allows free radical chemical reaction and addition to polymers
Be soluble in many organic materials.

Specification

Appearance: Clear to pale yellow liquid

Viscosity (25℃,cp): 40~3000 (as per the request of customer)

Vinyl content(%):0.5~3 (as per the request of customer)

APPLICATIONS
1. Be used as hardening fillers or dilue nts prior to vulcanization of big molecular weight and high viscosity silicone rubber 110-2.
2. Modifiers for polymers such as polyurethane, acrylic.
3. Can be used in making HTV and RTV silicone rubbers and silicone gel.
4. Other potential applications.

HOW TO USE
1. For use as diluents, advisable use level is 10~20%.
2. For use as modifier, advisable use level is 5~10%.
3. For use as silicone rubber gum, advisable use level is 50~100%.
Adding directly or using high-speed agitator to ensure dispersion uniform.

PRODUCT SAFETY INFORMATION
1. USi-OB4 should be stored in clean and closed polyethylene plastic containers.
2. Avoid contact with catalysts, acid, bases, or other materials which may cause denaturing of the fluid.

STORAGE
