Product Features & Advantages
1. Advanced Addition Curing Technology: Produces no by-products or toxic fumes during curing, ensures zero shrinkage and deep curing, making molds more precise and stable than those made with condensation curing silicone mold rubber.
2. Excellent Mold Precision: Optimized fluidity ensures full filling of intricate mold details, capturing even micro-textures, reducing rework rates for high-precision mold projects.
3. High Durability: High tensile and tear resistance, supporting 50~80 mold cycles, reducing mold replacement costs for batch production, superior to ordinary mold making silicone.
4. Safe & Eco-Friendly: FDA-certified food grade mold silicone, non-toxic, odorless, compatible with resin, metal, concrete, meeting global safety and environmental standards.
5. Easy Operation: 1:1 mix ratio, dual curing options, no professional equipment required, improving mold making efficiency for both small and large-scale production.
6. Full Customization: Color, hardness, operating time and curing time can be tailored to diverse mold making needs.
How to Use (Step-by-Step)
1. Mix Part A and Part B of the addition cure silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free (critical for mold precision and curing stability).
2. Vacuum degas the mixture for 2~5 minutes (time varies by viscosity, silicone weight and vacuum strength) to eliminate bubbles that affect mold quality.
3. Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details.
4. Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, fitting different mold production timelines.
5. Gently demold the cured silicone mold, clean before reuse; store unused silicone sealed indoors, away from sunlight and rain to preserve its addition curing performance.
Application Scenarios
This addition cure silicone is widely used in mold making silicone applications, including industrial mold silicone rubber production, rapid prototyping silicone molds, food grade mold manufacturing, metal craft molds, resin and polyester casting molds, precision handboards, cultural stone and concrete molds. It brings tangible value: improving mold precision and product qualification rate, reducing rework and replacement costs, simplifying operation to save labor costs, and helping suppliers meet the high-demand requirements of global mold manufacturing industries.
