Hydroxy Terminated Polydimethylsiloxane for RTV silicone

Product Description

 Description of Hydroxy silicone oil

Hydroxyl terminated is a series of functional polymers with different viscosities and different Terminal hydroxyl.

Appearance @ 25℃        Colorless Transparent Liquid

Specific gravity @ 25℃             0.980

Refractive index @ 25℃            1.4058


Application of Hydroxy silicone oil

1. Structure controlling agent for silicone rubber

2. Finishing agent for fabric, improve smooth and sewing properties of the polyester thread obviously and finish polyester fiber fabric

3. It can be anti-sticking treatment agent of high-grade papers

4. It can be used as the surface treatment of the filler and the high temperature resistance additive,

5. It can used in rtv silicone formula

6. It can be used as a reactive dilution to adjust the viscosity of the overall formulation.

7. The ultra high viscosity hydroxyl silicone oil are as below

A. It can be both used as a textile auxiliary to improve the film-forming and hand feeling

B. It can be used as a plastic processing auxiliary for improving the plastic properties as processing efficiency, discoloration and scratch resistant

 8. The series hydroxy silicone oil can do condensation reaction with the crosslinking agent (such as alcohol silane, silane and acid silane).And tin catalyst can speed the reaction.


Advantages of Hydroxy silicone oil

1. Different viscosities and different terminal hydroxyl

2. Hydroxy silicone oil can do condensation reaction with the crosslinking agent (such as alcohol silane, silane and acid silane).And tin catalyst can speed the reaction.
