It supports room/heat curing, high durability, and wide adaptability, helping purchasers avoid high-temperature failure, reduce production losses, and gain competitive advantages in diverse high-heat application markets.
Product Overview
Our Heat resistant silicone for use is a professional high-temperature solution engineered for versatile high-heat scenarios, composed of high-purity heat-resistant organic silicon raw materials (Part A: base rubber; Part B: curing agent) via advanced addition curing technology and strict quality control. It solves the pain point of ordinary silicone with poor heat resistance, deformation or aging under high temperatures, and limited application scope, which leads to production delays and cost losses. Unlike low-heat-resistant silicone, our heat-resistant silicone cures into a tough, stable elastic body, non-toxic odorless, with excellent tensile strength and dimensional stability, fully complying with global quality standards (FDA, RoHS, ISO), ideal for both industrial and daily high-heat uses.

Step-by-Step Usage Guide
1. Prepare a clean, dust-free environment to ensure product quality and heat-resistant performance.
2. Mix Part A and Part B at a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until fully blended and bubble-free (critical for stability and heat resistance).
3. Perform vacuum degassing for 2~5 minutes (adjust based on viscosity/weight) to remove trapped air, avoiding defects in finished products.
4. Pour the degassed heat-resistant silicone into molds or application areas, ensuring full coverage of required structures.
5. Cure at 25℃ for 4~5 hours, or accelerate at 80~120℃ for faster turnaround; post-cure at 150℃ for 1 hour to enhance heat resistance.
6. Store unused silicone in sealed containers indoors, avoid sunlight/rain, use within 10 months; keep away from N/P/S compounds to prevent curing failure and performance degradation.
