Product Performance
- Moderate system viscosity, good flowability after mixing, easy deaeration, long working time;
- High tear strength.
- Platinum vulcanization, environmentally friendly, safe and non-toxic;
Application Fields
Self-leveling base adhesive for powder mixing, electronic component encapsulation, high-strength potting base adhesive, high-strength silicone rubber products, etc.
Usage Instructions
- Mechanical stirring can be used for A/B mixing or static mixer for mixing;
- 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 rapidly shorten curing time, but for thicker products, note that overly fast curing may cause bubbles;
- Product performance after curing depends on curing conditions; best to test before curing to find optimal conditions.
Packaging and Storage
Packaging specifications: 1Kg and 25Kg, customizable per customer request. Store in a cool, dry, sealed place.
