Coating general knowledge: types of thickeners in architectural coatings

It is suggested that thickeners can be classified into organic and inorganic, natural and synthetic, swelling / dissolving and associating, etc according to their biological properties Commonly used thickeners for architectural coatings include HEUR (such as PU), hase (ASE), HEC (HMEC), inorganic bentonite, attapulgite, etc Characteristics of various thickeners: Polyurethane or HEUR thickener, non-ionic type, has the characteristics of surfactant, water, cosolvent and surfactant have great influence on the thickening effect Anti spatter, good leveling, improve film fullness; good scrub resistance Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: thickeners have many different classification methods, from biological organic, inorganic, according to the production mode of natural, synthetic, according to the way of silk swelling / dissolution, association, etc Commonly used thickeners for architectural coatings include HEUR (such as PU), hase (ASE), HEC (HMEC), inorganic bentonite, attapulgite, etc Characteristics of various thickeners: polyurethane or HEUR thickener, non-ionic type with surfactant characteristics, water, cosolvent, surfactant have a great impact on the thickening effect It has good resistance to splashing, leveling, and improving the fullness of the film; it has good resistance to scrubbing, alkali and thickening The latex paint is uniform without flocculation This kind of non flocculation paint has the potential of luster The film made of non flocculation paint is compact, good resistance to penetration and corrosion; it is not sensitive to electrolyte and has no biodegradation Alkali soluble or alkali swelling hase (ASE) thickener: anionic thickener, sensitive to pH, the thickened emulsion paint is a non-uniform flocculation system, with no luster potential It is sensitive to electrolyte and has no biodegradation Cellulose HEC (HMEC): non-ionic, pH insensitive, thickened emulsion paint is a non-uniform flocculation system, no luster potential, biodegradation Inorganic type: bentonite has great thixotropy, and has little effect on medium and high shear viscosity compared with alkali soluble or alkali swelling type and cellulose Formula selection, different decorative effects of the coating have different requirements for convective: in high PVC system, has660 is used alone or in combination with PU In mercerizing, semi gloss and high gloss coatings, HEUR with gloss potential, such as dsx3116, dsx3256, dsx1550, etc., shall be selected to avoid using a large number of thickeners with flocculation characteristics such as cellulose, reduce gloss and limit the improvement of PVC Small diameter, high emulsion, high pigment system, thickening curve with Newtonian Thickener (such as DSX3075) is selected to avoid thickeners with low and medium shear viscosity (such as T1550) Strong thixotropic roughing coating, strong thixotropic thickener dsx1130, dsx3290 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,
