KY-908 High Temperature Resistance, Water Proof Silicone Rubber for Fiber Glass Fabric
KY-908 Silicone rubber for fiber glass fabric
1. Product characteristics
KY-908 is one kind of Silicone rubber for fiber glass fabric, the KY-908 can be divided in to additional two component type and condensed two component type, which are special for fiber glass fabric. KY-908 has excellent adhesive ability with fiber glass fabric after curing, the fiber glass fabric will has perfect strength, high temperature resistance, wear resistance, grease proof and water proof ability after using this kind of silicone rubber.

3. Usage
1) Stirring A and B to uniformity before using.
2) Mixing A and B component according to A: B = 1:1 by weight,
3) coating the mixture to the fiber glass fabric.
4. Main application
Suitable for any kinds of fiber glass fabric and curtain canvas.
2. perfusing mixed A, B components after bubbles automatically vanishing; for fast-curing and high- viscosity encapsulation, should perfusion after pumping take off the bubbles by vacuum in the mixed A, B glue; For the components with tiny aperture, can perfusion firstly, then put components in vacuum device to taking off bubbles.
3. the surface hardness and curing time of this model potting rubber can be adjusted according to user’s requirement.
5.Application:
LED, power modules, electronic vigour pieces, screen, and other electronic products.
