Product Description

MF898 Silicone Weatherproofing Sealant RTV, Neutral, One-Part Silicone Sealant

DESCRIPTION / APPLICATIONS

SILANDE MF898 Silicone Weatherproofing Sealant, a one-part, RTV neutral-cure, architectural grade sealant, is a specified, premium performance weather sealing product specifically designed for general glazing and weather sealing in curtain wall and building facades.

TYPICAL PERFORMANCE

• 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.
• Ideal for expansion, connection, perimeter and other movement joints
• Suitable for use on extension/compression movement capability of up to ±50% of the original joint width.
• Excellent temperature stability: - 50°C to 180°C.
• High level of mechanical properties.
• High elasticity and high modulus.
• Resistant to ozone, stain resistance to non- porous materials such as aluminum, glass and stainless steel.

 LIMITATIONS
SILANDE MF898 should not be applied to:

• Not suitable for structural glazing applications.
• In designs where the silicone is encapsulated and without access to atmospheric moisture.
• Do not use when application surface temperatures below 4°C or exceed 50°C.
• Surface which will be painted, as painting over rubber is not recommended.
• Do not use water for tooling and do not apply to wet or damp surface.
• On surfaces that are continuously immersed in water.
