Product Description
Dowsil 995 Structural Silicone Sealant
A high-performance neutral cure sealant specifically designed for building curtain wall assembly applications.
Product Overview
Dowsil 995 is a one-component, high-strength, neutrally curing (oxime) silicone structural sealant engineered for structural glazing applications. This sealant offers excellent adhesion to most building materials without requiring a primer and complies with Chinese national standard GB16776-2025, holding China Green Building Material Product Certification (Three-Star).
Performance Characteristics
Upon exposure to atmospheric moisture, Dowsil 995 cures to form a durable, flexible silicone rubber elastomer. It provides exceptional resistance to weathering elements including sunlight, rain, snow, and extreme temperatures ranging from -40°C to +150°C, ensuring long-term performance and reliability in building envelopes.
