What are synthetic polymer waterproof coatings? Synthetic polymer waterproof coatings refer to single-component or multi-component waterproof coatings made from synthetic rubber or synthetic resin as the film-forming substance, which can adapt to more complex waterproof needs. So, what types are there?
Polymer waterproof coatings: Polymer waterproof coatings are made from asphalt as the main raw material, using water as the dispersion medium, and modifying and emulsifying asphalt with polymers to create polymer-modified asphalt waterproof coatings. This coating has good resistance to high and low temperatures and can be used in both hot and cold regions. It has excellent tensile properties and can fully adapt to the deformation of the substrate. It can be used alone for waterproofing or combined with waterproof membranes to form a reliable composite waterproof layer.
Polyurethane waterproof coatings: Polyurethane waterproof coatings are prepolymers containing isocyanate groups formed by the addition polymerization reaction of isocyanates, polyethers, etc., mixed with catalysts, anhydrous additives, anhydrous fillers, solvents, etc., to produce single-component polyurethane waterproof coatings. This type of coating is a reaction-curing (moisture-curing) coating, characterized by high strength, large elongation, and good water resistance. It has strong adaptability to substrate deformation.
Acrylic waterproof coatings: Acrylic waterproof coatings are single-component water-based waterproof coatings made from pure acrylic polymer emulsions with the addition of other additives. Acrylic waterproof coatings can be applied on wet surfaces; they use water as the dispersion medium, are non-toxic, odorless, and do not pollute the environment, making them environmentally friendly products; they are single-component, cold-applied, and can be applied using brushes, rollers, sprays, or scrapers; they have good aging resistance, elongation, elasticity, adhesion, and film-forming properties; the waterproof layer is a closed system, providing good overall waterproofing effects, especially suitable for the construction of irregular structural substrates; they can serve as a colorful protective layer for rubber asphalt-type black waterproof layers.
Polymer cement waterproof coatings: Also known as JS composite waterproof coatings, these are a type of organic material composed of polymer emulsions such as polyacrylate emulsions, ethylene-vinyl acetate copolymer emulsions, and various additives, combined with inorganic fillers such as cement, quartz sand, light and heavy calcium carbonate, and various additives through reasonable proportions to form a two-component, water-based building waterproof coating.
After reading the above introductions about synthetic polymer waterproof coatings, do you have a clearer understanding of synthetic polymer waterproof coatings? For complex waterproof projects, being adept at using suitable waterproof materials can often achieve twice the result with half the effort. Understanding the characteristics and application ranges of various waterproof materials is the first step to successfully completing waterproof engineering.
