Product Features & Advantages
This silicone rubber offers superior high and low temperature resistance, operating stably between -60℃ and 200℃ without cracking, hardening or deformation, adapting to harsh industrial and food processing environments. It has negligible shrinkage and outstanding dimensional stability, ensuring consistent, high-fidelity replication of complex prototypes and delicate molds. With robust tear strength, it resists wear, shear and damage, supporting repeated molding cycles to reduce production costs. It exhibits strong resistance to corrosive resin components, with a smooth, non-sticky surface for easy demolding. Additionally, it holds FDA food grade certification, being non-toxic, odorless and eco-friendly, fully safe for direct food contact molding applications.
How to Use the Product
Step 1: Thoroughly clean the master prototype and all molding tools to remove dust, grease and contaminants, preventing platinum cure inhibition that affects curing effect.
Step 2: Accurately weigh Part A and Part B according to the required mixing ratio (1:1 or 10:1) to ensure balanced formulation.
Step 3: Stir the two components slowly and uniformly until fully blended, avoiding rapid stirring that generates excess air bubbles.
Step 4: Conduct vacuum defoaming for 2-3 minutes to remove internal bubbles; if no vacuum equipment is available, pour the mixture slowly along the mold frame to minimize bubble formation.
Step 5: Assemble a mold frame with plastic or wooden plates around the prototype, then apply a thin layer of release agent (detergent or soapy water) on the prototype surface. Step 6: Slowly pour the defoamed silicone mixture into the mold frame, let it stand and cure completely at room temperature to obtain a high-precision finished mold.
Important Cautions for Platinum Cure Silicone
This RTV2 silicone adopts a platinum catalyzed system, which is highly prone to cure inhibition. During operation, strictly avoid contact with Tin cure silicone rubber, sulfur/sulfide materials, amine compounds, pewter solder flux and related substances, as these will cause incomplete curing or complete non-curing. Always keep prototypes, tools and operating environments clean to guarantee normal curing and qualified molding quality.
Application Scenarios
This high temperature silicone is widely used in rapid prototyping fields such as urethane casting, silicone tooling and vacuum casting, as well as GRC/concrete molding, PU resin casting and general industrial mold manufacturing. It also serves as a reliable food grade mold silicone for food safe molding projects, including baking, candy and edible product molds. Its excellent thermal resistance and high precision help manufacturers improve production efficiency, reduce mold scrap rates, and achieve stable, high-quality batch production across industrial and food processing sectors.
