Description
SILANDE MF881 Part A is the base component of a two-component structural silicone sealant system designed for high-performance structural glazing applications. It is a high-viscosity polymer compound that reacts with Part B (curing agent) to form a durable, elastic, and weather-resistant silicone sealant. The final cured system provides excellent adhesion to glass, coated glass, aluminum, and stainless steel, making it suitable for curtain wall and façade applications.
Spec & Technical Data
SILANDE MF881 Part A is a high-viscosity base polymer component used in a two-component structural silicone sealant system. It is designed to be mixed with Part B (curing agent) to form a high-performance elastic silicone material suitable for structural glazing and curtain wall applications. The material remains stable in sealed storage conditions and is processed under controlled mixing ratios typically ranging from 11:1 to 14:1 by weight depending on system requirements. After proper curing with Part B, the system delivers high mechanical strength, excellent adhesion to glass, coated glass, aluminum, and stainless steel, along with superior resistance to UV radiation, weathering, and temperature extremes ranging from -60°C to +180°C. The product is supplied in industrial drum packaging and is intended for professional application in architectural glazing systems.
