2. High Casting Precision: Excellent fluidity fills tiny casting details, shrinkage rate ≤0.05%, ensuring casting molds retain shape and precision, reducing casting defects.
3. Food-Grade Safety: FDA, RoHS and EN71 certified, non-toxic, odorless, no harmful by-products, suitable for food-contact casting molds and high-standard casting scenarios.
4. High Durability: High tensile and tear strength, supporting 95~115 mold cycles, extending service life and reducing mold replacement costs for purchasers.
5. Easy Operation & Customization: 1:1 mix ratio, simple stirring; hardness, operating time, curing time, and color can be tailored to diverse casting mold requirements.
6. Stable Batch Quality: Standardized production and strict quality control ensure consistent platinum curing performance, error ≤2%, avoiding quality fluctuations in mass casting.
How to Use (Step-by-Step for Casting Mold Making)
1. Mix Part A and Part B of the platinum silicone compound in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free, ensuring full integration of the platinum curing agent.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity to eliminate bubbles and avoid casting mold surface defects.
3. Pour the degassed silicone into casting mold masters, leveraging good fluidity to fill all details and gaps, ensuring precise replication.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to meet casting production schedules.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months; platinum formula maintains stable performance during shelf life.
Application Scenarios
Our Platinum Silicone Compound For Casting Molds is widely used in global high-precision casting mold manufacturing, including high-simulation food casting, metal crafts, alloy car accessories, epoxy resin/polyester resin casting, large cement components, cultural stone, concrete casting, and precision handboard models.
