Product Features & Advantages
Oil-free formula: Maintains clean mold surfaces and finished products, avoiding contamination and prolonging service life.
Superior durability: Higher tensile/tear strength than standard silicone, resistant to acid and alkali for harsh working conditions.
Ultra-low shrinkage: Preserves precise dimensions of molds and finished parts, ensuring consistent product quality.
Extended shelf life: Reduces material waste and inventory costs for long-term storage.
Easy maintenance: Repeated cleaning without damaging surface performance, keeping molds in optimal condition.
Broad adaptability: Covers 8 major application fields, replacing multiple single-purpose silicones to cut procurement costs.
How to Use the Product
Step 1: Select the curing system – addition cure for precision/food contact, condensation cure for cost-effective mass production.
Step 2: Weigh Part A and Part B strictly according to the specified mixing ratio using an electronic scale.
Step 3: Stir the mixture thoroughly and evenly to avoid partial curing or performance defects.
Step 4: Apply via pouring, brushing, potting or filling according to the specific application scenario.
Step 5: Cure at room temperature (or heat-cure for accelerated speed) and demold/use after full curing.
Application Scenarios
Mold Making: GRC, plaster, stone, cement, resin products, shoe mold, tire mold and bag hardware fitting molds.
2. Food Grade Molds: Cake, chocolate, candy and special food molds (addition cure only).
