Waterproof coating refers to a kind of coating that can prevent rainwater or groundwater from leaking. According to the coating state and form, it can be divided into solvent, emulsion and modified asphalt. Let's learn more together! The first kind of solvent-based coatings: This kind of coatings has many varieties and good quality, but it has high cost, poor safety and is not widely used. The second category is aqueous emulsion and reactive polymer coatings: it is difficult for all kinds of reinforcing agents, fillers and polymer elastomers in these coatings to be evenly dispersed in the colloid, and only a small amount of additives can be added through grinding. Reactive polyurethane is two-component, easy to deteriorate and high in cost. The third kind of plastic modified asphalt: these products are resistant to ultraviolet rays and high temperatures, but the elongation at break is slightly poor.
