Coating classification: water resistance of coating film

Core tip: poor water resistance of paint film will lead to discoloration or fading, loss of light, blistering, pulverization, peeling and granulation, cracking and falling off of paint film, alkali coating, flower coating, watermark coating, etc., which will reduce the performance of coating system and end the service life prematurely The following measures are taken for water resistance of paint film: The film-forming material is hydrophobic The resistance of paint film to water is due to the drainage of film-forming materials The hydrophobicity of film-forming materials requires that the binder and emulsion hydrophobicity of paints: hydrophobic surface treatment of hydrophilic pigments and fillers, hydrophilic pigments and fillers to be treated with water dispersible agents, and the solid parts of the auxiliaries are water-soluble Water penetration resistance, coating surface Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: poor water resistance of paint film will lead to discoloration or fading, loss of light, blistering, pulverization, peeling and granulation, cracking and falling off of paint film, alkali coating, flower coating, watermark coating, etc., which will reduce the performance of coating system and end the service life prematurely The water resistance of paint film has the following measures: film-forming material is hydrophobic The resistance of paint film to water is due to the drainage of film-forming materials The hydrophobicity of film-forming materials requires that the binder and emulsion hydrophobicity of paints: hydrophobic surface treatment of hydrophilic pigments and fillers, hydrophilic pigments and fillers to be treated with water dispersible agents, and the solid parts of the auxiliaries are water-soluble The surface of the film is compact, continuous, perfect and smooth, flat without pinhole, shrinkage cavity, crater and certain coating, which can reduce the penetration of water to the coating The formulation of the coating should be designed to reduce water as much as possible and improve the volume value of nonvolatile The hydrophobic treatment of the coating surface, adding a small amount of hydrophobic agent in the coating, forming a hydrophobic film on the surface of the coating film, can effectively block the infiltration of rainwater and improve the water resistance of the coating film Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
