Really stone paint coating and its prevention countermeasures is too soft

Really stone paint for its adornment sex is strong, wide applicable scope, durability, and good color fastness and become a popular exterior decorative coatings. However, in the construction and application of really stone paint, often appear some issues which affect the quality and the adornment effect, these problems are very common. These problems are made from improper selection of raw materials, formula and construction method is not correct. This article main discussion: from the perspective of raw materials and formulation. High quality really stone paint coating should be very hard, and can't shave her nails. If in case the weather is good, the construction of the three days later you can also use nails dig, coating should be considered too soft. True stone lacquer is too soft is the major reason for the choice of the emulsion is not appropriate. Many manufacturers in the preparation of true stone lacquer is used when the same emulsion and latex paint, this is wrong. Really stone paint formulation emulsion content is relatively low, because there are a lot of sandstone in the film-forming process, coating is dense enough. Therefore, we should choose high adhesion and high minimum film-forming temperature of latex. According to research, really stone paint used in the preparation of emulsion adhesive strength should not be less than 3 mpa, the minimum film-forming temperature should not be less than twenty degrees Celsius. Higher minimum film-forming temperature may result in air at low temperature is not easy to film defects, this can be achieved by adding more appropriately film additive to solve. Film forming additive in completely volatilize after coating is dry, generally does not affect the performance of the coating.
