3. Advanced Addition Curing: Ensures uniform, shrink-free deep curing, no toxic by-products, and stable batch performance, complying with global industrial quality standards.
4. Safe & Compliant: FDA and RoHS certified, non-toxic, odorless, suitable for Food grade mold silicone and high-demand industrial scenarios requiring safety and durability. 5. Easy Operation & Flexibility: 1:1 weight ratio for simple mixing, dual curing options; hardness, operating time, and curing time can be customized to match diverse durable molding needs.
6. Long-Term Stability: Resists aging, oxidation, and chemical corrosion, maintaining performance integrity even after long-term storage and repeated use, ensuring consistent production results.
How to Use (Step-by-Step for Durable Molding)
1. Mix Part A and Part B of Durable Liquid Silicone Materials in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free—ensuring consistent durability after curing.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity, weight, and vacuum intensity to eliminate bubbles and ensure mold integrity.
3. Pour the degassed silicone into the mold master, leveraging its good fluidity to fill all details and form a strong, durable structure.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to retain superior durability and high-temperature resistance.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months to maintain its durable performance; avoid contact with organic tin compounds and sulfur-containing materials to prevent performance degradation.
Application Scenarios
Our Durable Liquid Silicone Materials are widely used in global industrial and high-demand molding scenarios, including Industrial mold silicone rubber, large cement components, cultural stone, concrete molds, metal crafts, alloy car accessories, high-frequency replication molds, and harsh-environment industrial applications. It brings tangible value: reducing mold replacement costs by 45%+, improving production efficiency, ensuring stable performance in extreme conditions, and supporting long-term mass production, helping B2B purchasers reduce costs and enhance competitiveness in the durable liquid silicone market.
