MF899
Silicone Structural Sealant
RTV, Neutral, One-Part Silicone Sealant for Structural Glazing
♦ DESCRIPTION / APPLICATIONS
SILANDE MF899 Silicone Structural Sealant, 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.lt easily extrudes in any weather and cures at ambient temperature by reaction with moisture in the air to form a durable, flexible silicone rubberseal.
- 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.
- 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: - 60°C to 180°C.
- High level of mechanical properties.
- High elasticity and high modulus.
- Resistant to ozone.

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

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.
