Product Features & Advantages

Premium Performance for Perfect Molds: Superior fluidity ensures full filling of intricate mold cavities, while ultra-low shrinkage (≤0.1%) guarantees precise detail replication—achieving flawless mold results that outperform ordinary Mold Making Silicone and Condensation Curing Silicone Mold Rubber.

Advanced Addition Curing Technology: No by-products or odor during curing, clean and eco-friendly, meeting global high-quality mold standards and ensuring safe production.

Exceptional Durability: High tensile and tear resistance support 60~80 mold cycles, reducing replacement costs and ideal for long-term batch production of premium molds.

Wide Compatibility & Safety: FDA-certified, non-toxic, odorless, and compatible with resin, metal, concrete, and other substrates, versatile for diverse premium mold scenarios.

Full Customization: Tailorable hardness, fluidity, operating time, and curing time to adapt to different premium mold manufacturing needs, with standardized production ensuring consistency.

Brand Assurance: As a national high-tech enterprise, we provide one-stop solutions and professional technical support, guaranteeing premium quality for every batch.

How to Use (Step-by-Step)

Mixing: Combine Part A and Part B of the premium liquid silicone in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes until uniform and bubble-free—critical for achieving perfect mold details and surface quality.

Vacuum Degassing: Subject the mixed silicone to vacuum treatment for 2~5 minutes (adjust based on viscosity, weight, and vacuum pressure) to eliminate bubbles that affect mold perfection.

Pouring: Slowly pour the degassed silicone into the master mold, leveraging its excellent fluidity to ensure full coverage of all intricate details and cavities.

Curing: Cure at room temperature (4~5 hours) or heat at 80~120℃ for accelerated curing, ensuring stable performance for premium mold results.

Demolding & Storage: Gently demold the cured silicone mold, clean thoroughly before reuse. Store unused silicone in a sealed container indoors, away from sunlight and rain to preserve its premium properties.
