Product Overview
Our Food Grade Silicone Casting Material is a professional food-contact solution engineered for safe, precise casting applications, composed of food-safe ultra-pure organic silicon raw materials (Part A: base rubber; Part B: curing agent) via advanced addition curing technology. It solves the pain point of ordinary casting silicones with toxic residues, non-compliance with food safety standards, and poor casting precision. Unlike non-food-grade alternatives, our material cures into a clean, soft, and stable elastic body, non-toxic odorless, free of harmful substances, ideal for food-grade casting, simulation food molds, and food-contact crafts, fully complying with global food safety certifications.

Step-by-Step Usage Guide
1. Prepare a clean, dust-free, and contaminant-free environment to ensure food safety and casting precision.
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.
3. Perform vacuum degassing for 2~5 minutes (adjust based on viscosity/weight) to remove trapped air, avoiding casting defects.
4. Pour the degassed material slowly into casting molds, ensuring full coverage of all fine details.
5. Cure at 25℃ for 4~5 hours, or accelerate at 80~120℃ for faster turnaround; post-cure enhances safety stability and durability.
6. Store unused material in sealed containers indoors, avoid sunlight/rain, use within 10 months; keep away from N/P/S compounds to prevent curing failure.
