Glazing Neutral Adhesives Weatherproof Silicone Sealant
Glazing Neutral Adhesives Weatherproof Silicone Sealant
DESCRIPTION:
899, a one-part, RTV neutral-cure, architectural grade sealant, designed specifically for the structural bonding of glass, metal, and other building components. It can also be used to adhere stiffening elements to building panels and for other similar adhesive applications. It easily extrudes in any weather and cures at ambient temperature by reaction with moisture in the air to form a durable, flexible silicone rubber seal.
FEATURE:
●Excellent adhesion to a wide range of substrates including coated glass,galvanized steel,masonry, anodized and polyester paint coated aluminium and stainless steel and other porous and non- porous substrates.
● High ultimate tensile strength makes it ideally suited for structural bonding application.
● Excellent weathering characteristics and high resistance to ultra-violet radiation,heat and humidity.
●Excellent temperature stability;-50"C to 180℃.
● High level of mechanical properties.
● High elasticity and high modulus.●Resistant to ozone.
