Polymer cement waterproof coating reaction type and volatile type What is the difference
Reaction type of easy to use, the oil-based paint to the main reaction type, the water-based volatile type, if it is necessary, you can also try to winter polyurea waterproof coating products, should be on the market the best overall performance Products, high-speed rail waterproofing it accounted for 80% of the market share, the other concrete roof waterproof, color steel tile roof waterproof, swimming pool waterproof, dam waterproof and so easy to use, can solve the traditional paint intolerant aging (QUVA test 1500h), strength Not high (aspartic pull strength> 15Mpa, elongation> 300%) and other issues, if any project is not a good solution, you can try winter polyurea it.
What is grafted polymer?
Basic definition: Graft copolymer: A copolymer of a side chain of a polymer segment that is different from the main chain chemical structure on certain atoms of the polymer backbone, referred to as a graft copolymer, Such as grafted neoprene, SBS graft copolymer. Description: The so-called graft copolymerization refers to the macromolecule chain through the chemical bond to the appropriate branch or functional side of the reaction, the formation of the product is called graft copolymer. The properties of the graft copolymer are determined by the composition, structure, length and number of branches of the backbone and branches. The long branches of the grafted counterparts are similar to the blends, the branches are short and the larger grafts are similar to the random copolymers. By copolymerization, two different properties of the polymer can be grafted together to form a special graft. Therefore, the graft modification of the polymer has become a simple and effective method to expand the application of polymer and improve the performance of polymer materials.
