Product Performance
- Moderate system viscosity, high flowability, easy degassing;
- High modulus, high elasticity;
- Platinum-catalyzed curing, environmentally safe and non-toxic;
Application Areas
Electronic encapsulation, molding, special products
Usage Instructions
- A/B components can be mixed by mechanical stirring or using a static mixer;
- Clean instruments and equipment before use; substances containing tin salts, amines, or sulfur may inhibit the curing reaction;
- Can be cured and molded in the temperature range of 40-150℃;
- Increasing curing temperature can significantly shorten curing time, but for thicker products, note that overly fast curing may cause bubbles;
- Post-cure properties depend on curing conditions; it is best to test before curing to find optimal conditions.
Packaging and Storage
Packaging: 1Kg and 25Kg, or customized per customer requirements. Store in cool, dry, sealed conditions.
