Cost-Effective Storage: Expired (1+ year) silicone can be re-stirred to restore viscosity (minimizing material waste).
How to Use
Stir Component A and B separately in their containers to ensure uniformity.
Mix A:B = 1:1 (weight), stirring thoroughly for consistent blending.
Degas at 0.01MPa for 5 minutes to remove air bubbles (for smooth product surfaces).
Pour the mixture into molds; cure at room temperature (8 hours) or heat (80-100℃ for 20 minutes) (faster in winter).
Application Scenarios
