Product Introduction
Neutral Construction Exterior Engineering Silicone Sealant is engineering-grade neutral weatherproof silicone sealant developed for outdoor construction, external curtain wall and door and window projects. Adopting premium alcohol-based neutral curing system, it overcomes poor weather resistance of indoor sanitary sealants and substrate corrosion caused by acidic adhesives. Featuring four core engineering performances: long-term outdoor anti-aging, high movement accommodation, waterproof sealing and zero substrate corrosion, it is standard dedicated caulking material for commercial outdoor projects and building facade sealing.
Core Product Advantages
- Engineering-grade weather and aging resistance for long outdoor service: Formulated with imported UV, ozone and anti-aging additives, the exclusive outdoor formula withstands long-term strong sunlight, rain/snow erosion, freeze-thaw cycles and coastal salt spray corrosion.
- Non-corrosive neutral formula compatible with all substrates: Pure alcohol neutral curing system free of acidic corrosive ingredients and harmful bleed-out, eliminating metal corrosion and stone oxidation triggered by acidic glue.
- High elasticity and movement capability to prevent crack and peeling: High-level movement compliance complying with national standards accommodates thermal expansion/contraction and slight structural shake of exterior wall and window profiles with outstanding elastic recovery.
- Excellent workability for bulk construction: Smooth easy-extrusion paste with superior thixotropy avoids sagging, intermittent or hollow beads on vertical and overhead high-rise surfaces.
- Eco-friendly formula for smooth project acceptance: Solvent-free low-VOC compound releases no pungent odor or hazardous volatiles after curing without environmental pollution.
