MF910/ MF910G/MF910T Insulating glass with butyl hot-melt sealant: used for the first sealing of insulating glass, it can form an excellent anti-moisture system together with elastic sealant.
Insulating glass (channel aluminum type) must adopt a double-sealing method to ensure its sealing and durability. That is to say, the first seal adopts hot-melt butyl sealant, which is mainly used for sealing; the second seal is completed by elastic sealant, which plays the role of auxiliary sealing and maintaining the stability of the insulating glass structure. The two complement each other and are indispensable.
At present, most of the hot melt butyl sealant products on the market, whether imported or domestic, are mostly black in color. Our company has also developed transparent, gray and white hot melt butyl sealants.

What are the influencing factors of butyl sealant in the construction process?
The main influencing factors are:
Heating temperature, extrusion pressure, belt speed, extrusion equipment (manufacturer, old and new), pressing time;
Construction environment temperature;
The regularity and cleanliness of the spacer;
Operating habits of workshop staff.

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.
