Product Introduction
Professional-grade Liquid Silicone Rubber specifically engineered for high-precision mold making applications. This two-component RTV (Room Temperature Vulcanizing) silicone system offers exceptional flowability, dimensional stability, and detail reproduction. With low shrinkage and excellent tear strength, it's ideal for creating complex molds in industrial, artistic, and prototyping applications. The product meets FDA, ROHS, and REACH standards, ensuring safety for diverse molding requirements.
Product Advantages
l Superior Detail Reproduction
Precisely captures intricate surface patterns and textures with exceptional accuracy. Ideal for projects requiring microscopic detail retention.
l Excellent Flow Properties
Smooth, self-leveling characteristics ensure complete mold cavity filling. Minimizes the risk of air entrapment and void formation during pouring.
l Fast Curing Time
Quick room temperature curing enables faster production cycles. Maintains dimensional stability throughout the curing process for reliable results.
l High Tear Strength
Excellent resistance to tearing during demolding and repeated use. Ensures longer mold life and consistent performance over multiple casting cycles.
l Minimal Shrinkage
Maintains original dimensions after curing for precise reproductions. Guarantees accurate final parts that match original specifications.
l Long Pot Life
Provides adequate working time for complex mold making projects. Allows proper degassing and precise placement without premature curing.
