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.

♦ TECHNICAL DATA - TYPICAL PROPERTIES
MF322 two-component polyurethane corner glue
Mainly used for bonding and sealing between aluminum alloy corners and profile cavities in aluminum alloy door and window structures; suitable for bonding wooden doors, windows and doors; for processed different materials, such as wood, building materials, ceramics and metals It has good adhesion.
How to use instructions
Remove dirt, dust, oil, frost, etc. on the surface of the substrate; place the plastic nozzle on the open bottle mouth and tighten it, and use a dedicated 1:1 double bottle glue gun to inject glue. Uncured glue can be cleaned with special cleaning agents (or other solvents such as alcohol).

Packaging

Packaging
1:1 double plastic bottle packaging: 600 ml per group; 9 groups per carton

Transport transmission
This product is non-hazardous and can be transported by train, car, ship and plane

Store
Can be stored for 6 months in a cool, ventilated and dry place.

Precautions and precautions
The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
The glue mixed at room temperature should be used during the application period.
Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
avoid contact with children; do not contaminate food, medicine or cosmetics.
The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.
