The choose and buy to see what really stone paint

At present, really stone paint there are many brands on the market, quality is uneven. Really stone paint and low price is also high. Some customers will focus on the high price products, to ensure the quality of really stone paint. They only buy high prices really stone paint. In fact, it is not appropriate, because a in high prices really stone paint has low quality products. This is a lack of judgment. So, when we buy really stone paint, should see what? Let's share with you. From the point of resin material system, it is divided into styrene - Acrylic acid, pure acrylic and silicon Acrylic acid. Differences in really stone paint water resistance, weatherability and stain resistance, namely really stone paint effect of persistence. Up to 15 20 years, the minimum up to 3 - For five years. Performance comparison: pure c styrene acrylic and styrene acrylic 1 and really stone paint fixed after coating is dry, the coating hardness is very hard, nail cannot pull out. If the ordinary really stone paint in good weather conditions construction will still be a nail scratch, three days after coating should be considered too soft. The main reason is to choose the emulsion is not appropriate. In the preparation of really stone paint, using the same emulsion and latex paint, cause really stone paint formulation emulsion content is low, and because there are a lots of sand and gravel in the film-forming process, coating is dense enough. According to the research of the coating to the researchers, 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 below 15 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 will not affect the performance of the coating. True stone lacquer is a kind of high adhesion and high minimum film-forming temperature of composite emulsion, fundamentally solve the problem of the coating is too soft. 2. Good water resistance of the coating, color stability, not white, colorless difference every time it rains some really stone paint coating efflorescence, coating will become loose. However, after the rain stopped, the coating exposed in the sun will return to its original color. In fact, this is caused by poor water resistance of coating and water imbibition. The formula is based on the fact that the surfactants should be added to the selection used in synthesis of acrylic emulsion. In order to improve the stability of the emulsion, some manufacturers use more surfactant. Some manufacturers to join in the preparation of really stone paint materials such as carboxymethyl cellulose, hydroxyethyl cellulose as a thickening agent, sodium benzoate as a preservative. These substances are water-soluble or hydrophilic, when after the film coating in coating, the water resistance of coating is reduced greatly. Experiments show that in the case of not add any additives, spraying pure acrylic emulsion and quartz sand coating formed by bibulous rate is 0. 42%. On the other hand, add 0 in the coating. 4% hydroxyethyl cellulose, bibulous rate is increased to 4. 3%. Because really stone paint coating is relatively thick, suction, once it is not easily released in a short period of time, resulting in loose white appearance and internal coating. After drying has good resistance to water, so dry coating after the water won't become white. Above is edge xiao when choosing really stone paint to let everyone share would like to see. When customers pay attention to these aspects, whatever the price, they can choose the moderate price, good quality, really stone paint.
