Details

Hydroxyl silicone oil 1647 V75

Description :

1647 V75 is a low-viscosity, linear α,ω- hydroxypropyl polysiloxane fluid.

Applications:

1647 V75 carbinol silicone may be used as an intermediate in the manufacture of silicone/polyester or silicone/polyurethane copolymers.

It is used in place of, or in addition to, the "diol" part of these polymers.

Having an α,ω-hydroxyalkyl functionality, the silicone is permanently co-polymerised into the chains or cross-linked matrices of the polyester or polyurethane.

This carbinol silicone co-polymer may also be used as an additive in polyester- and polyurethane-based paint to improve properties.

ZINCA 1647 V75 imparts the typical properties of silicones to polyesters and polyurethanes:

1. Non-stick properties

2. Abrasion resistance

3. Scratch resistance

4. Lubrication

5. Water repellency

6. Weatherability

7. Plasticity

8. Low temperature flexibility

9. High temperature stability

10. Electric insulation
