Polymer cement waterproof coating reaction type and volatile type What is the difference
Polymer cement waterproof coating are generally reflective type, the current market of polymer cement waterproof coating are propylene-based, there is no reflection of the type of reactive water-resistant materials are generally epoxy class.
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.
As the polyurethane is also a polymer, the ratio is also inorganic powder, and polyurethane curing is the reaction with the water and film, so called reactive polymer cement waterproof coating, is actually wrong.
In recent years, there is a reactive polymer cement waterproof coating, its composition is water-cured polyurethane + inorganic powder, his performance and the standard polymer cement waterproof coating is completely different, film form, after film mechanical properties, He should belong to a polyurethane waterproof coating, and should not be counted as a polymer cement waterproof coating.
Generally refers to the polymer cement waterproof coating is composed of polymer emulsion + inorganic powder compound, the polymer emulsion is water-based, the construction can be appropriate to add water. After the paint is painted on the base surface, the moisture evaporates to form the coating. So the polymer cement waterproof coating is usually volatile curing type.
