Polyurethane waterproof coating density and characteristics, don't let the home so "tidal"

Polyurethane waterproof coating is a liquid construction of a single-part environmental protection waterproof coating, often used in roofs, toilets, basements, cisterns, external walls and other walls prone to water resistance, impermeability, moisture, reinforced concrete structure can be this layer of "coat" well protected. So what is the density of polyurethane waterproof coating?
single-component polyurethane waterproof coating is a pre-polymerized body containing isocyanate based on isocyanate, polyether and other polymerization reaction, and then equipped with catalysts, waterless additives, waterless fillers, solvents, etc., processed by mixing and other processes made of single-component polyurethane waterproof coating. According to the national standard "polyurethane waterproof coating" GB/T19250-2013, there are no special requirements for the standard of coating density, but the density of single-component polyurethane waterproof coating is generally 1150 to 1250 kg/m3

after understanding the density of polyurethane waterproof coatings, we would like to know what the characteristics of polyurethane waterproof coatings?
Polyurethane waterproof coating can be directly constructed on a variety of wet or dry substrates, and the polymer substances in the coating film can penetrate into the substrate fine seams, the substrate bonding force is very strong, its coating film has good flexibility, the grass-roots telescopic or cracking adaptability, high pull strength. In addition to polyurethane waterproof paint green environmental protection, non-toxic tasteless and pollution-free, there is a good weather resistance, encounter high temperature will not disperse, encounter low temperature will not crack, with good durability, oil resistance, wear resistance, acid and alkali erosion. Polyurethane waterproof coating density is high, waterproof layer is complete, no cracks, pinholes, bubbles, water vapor will not easily penetrate, not only waterproof but also insulation. The most important thing is that polyurethane waterproof coating construction is very simple, high construction efficiency, post-repair is also very convenient, coupled with its weight itself is lightweight, not easy to increase the load on the building. Finally, polyurethane waterproof paint color is also many different, according to their own needs to be provisioned a variety of colors.
polyurethane waterproof coating is divided into two parts and single parts, whether double or single, are asphalt-based environmental protection materials, however, compared to a single part of polyurethane waterproof coating to be more excellent, polyurethane waterproof coating construction is convenient, overcome the two-part polyurethane waterproof coating needs to measure the shortcomings of mixing, and can be applied to complex construction projects, its product quality is particularly stable, thus ensuring the waterproof effect of the project.
believe that we have learned the density and characteristics of polyurethane waterproof coating, polyurethane waterproof coating should have a certain understanding of it! Waterproof is a very important job in decoration, in order to later can be more relaxed life must pay more attention to waterproof work involved in all aspects, such as waterproof materials, if you do not understand polyurethane waterproof paint, you can choose the brand polyurethane waterproof paint.
