Anti-Yellowing UV Resistant RTV2 Silicone Liquid Rubber

HY-RTV2-UV15 is a premium condensation cure (RTV2) silicone liquid rubber specifically formulated for outdoor mold making applications where long-term color stability and UV resistance are critical. Unlike conventional tin-cure silicones that yellow within months of sun exposure, this anti-yellowing formula maintains its clarity and mechanical properties even after prolonged outdoor use.

Key Features

• Superior UV Resistance: Passes 1000-hour QUV accelerated aging test with no visible yellowing, ensuring molds stay clear and functional season after season.
• Anti-Yellowing Formula: Special stabilizer package prevents polymer degradation caused by sunlight, heat, and environmental factors.
• Condensation Cure at Room Temperature: Simple 100:2 mixing ratio cures at ambient temperature without requiring ovens or special equipment.
• Adjustable Hardness (15-35 Shore A): Available in multiple hardness grades to match your specific demolding requirements, from ultra-soft to medium-firm.
• High Tear Strength: ≥18 kN/m tear resistance ensures durable molds that withstand hundreds of casting cycles.

Typical Applications

Technical Advantages

• Temperature Range: Maintains elasticity from -40°C to +200°C, suitable for extreme climates.
• Low Viscosity (10000-30000 mPa·s): Excellent flow captures the finest details without vacuum degassing in most cases.
• High Elongation (≥400%): Allows easy demolding of complex shapes without tearing.
• Minimal Shrinkage: Ensures dimensional accuracy for precision casting projects.
• Long Pot Life: 30-45 minutes working time for comfortable large-scale mold making.
