Adhesives are the first generation and the adhesive bar and the second generation of distinction

Planting bar glue adhesives are JGN adhesive bar and the first generation of the main chain of the seam an agent products in the United States: unsaturated polyester resin reaction seam an agent in the United States: styrene benefits short curing time convenient operation cost is low durability performance is poor, the alkaline resistance low low flash point ( 31℃） Harmful to the environment pollution, human health styrene main defects of unsaturated polyester resin is used as a reaction the seam an agent, alkaline resistant ability is low. On construction site, the resin can absorb water slowly, this process resulted in the hydrolysis reaction of the resin, which can interrupt the resin molecular chain. This can also be called saponification effect ( Alkaline hydrolysis reaction) Suddenly Mrs, it will reduce the resin molecular chain length of the strength of the resin, so the strength of the adhesive to about a 40% reduction after four years, Average) , the biggest reduction can reach 60%. The second generation of planting-bar adhesive - beautiful seam an agent products Rubber bar and main chain: vinyl ester reaction seam an agent in the United States: styrene benefits Gao Huaxue stability harmful to human body health, moisture and high temperature environment bearing capacity decreased and unstable this kind of material is the main drawback of curing the seam an agent styrene containing carcinogenic. DFG（ German research association) Styrene has been listed as the fifth kind of carcinogen, in a high degree of exposure to such material environment control should be strengthened.
