Generally, the curing speed of the Best MS SEALANT FOR CONSTRUCTION supplier china is slow. To accelerate the curing speed and improve the initial adhesion, 1-3% triethanolamine or diethylamine ethanol can be added. It is also possible to use methacrylic acid light acrylic ester as a capping agent, introduce the olefinic bond into the polyurethane chain, and use UV light to initiate, so as to obtain a fast curing the Best MS SEALANT FOR CONSTRUCTION supplier china.

In addition, a certain amount of fillers (such as kaolin, diatomite, fumed silica, etc.) can be added into the Best MS SEALANT FOR CONSTRUCTION supplier china to increase the hardness and heat resistance of the adhesive film. If the silver powder prepared by the reduction method is added to the adhesive, the polyurethane conductive adhesive is formed.

In a word, the Best MS SEALANT FOR CONSTRUCTION supplier china is developing rapidly at home and abroad, with more and more varieties, and its production and application scope is also rapidly expanding and promoting. In order to meet this need, more and better the Best MS SEALANT FOR CONSTRUCTION supplier china must be developed through molecular design with a target in mind.

Before using the Best MS SEALANT FOR CONSTRUCTION supplier china, check the full performance qualification report and sealant re inspection report of this year. The re inspection contents include: hardness of the Best MS SEALANT FOR CONSTRUCTION supplier china and tensile adhesion at 23 ℃.

1) Adhesion of various sealants to different substrates

① Silicones have good bonding effect with glass, aluminum and stone materials, and are suitable for glass and stone curtain walls.

② The bonding effect of polyurethane with cement mortar board and stone is good, and it is suitable for sealing the gap between cement mortar board and stone.

③ Polysulfide has good bonding effect with glass and is suitable for secondary sealing of insulating glass.

④ The bonding degree between acrylic acid and cement mortar board is better than that of other materials, which is suitable for sealing between cement mortar boards.

2) The Best MS SEALANT FOR CONSTRUCTION supplier china and stone sealant used in curtain wall engineering shall be the same as the Best MS SEALANT FOR CONSTRUCTION supplier china, and compatibility test shall be added.

3) From the perspective of testing, the contamination of various sealants is seen. When sealant is used to seal between stone materials and cement mortar plates, there is a problem of substrate pollution. Polyurethane sealant and acrylic sealant have less pollution to the substrate, while MS sealant has more pollution. In the application of stone curtain wall, MS sealant for stone shall be used instead of MS sealant. Although MS sealant can obtain pollution-free results in the test, due to some problems in the test standard, when the Best MS SEALANT FOR CONSTRUCTION supplier china is used as the sealing material between stones in practical projects, pollution will still occur after a period of time.
