In the coating industry, the foam problem of water-based latex coatings is the most significant. In order to reduce the interfacial tension between water and the painted surface, a certain proportion of surfactants, such as wetting agents, dispersants, and leveling agents, are usually added to the product. , their presence promotes the stability of foam products. The implementation process changes the free energy of the system to varying degrees, which contributes to the generation of foam. The amount of defoamer used for water-based adhesives is not large, but the effect is obvious. For the foaming phenomenon of water-based and non-water-based coatings, mineral oil, alcohols, lipidated substances and other substances can have good diffusivity, reduce surface tension, and achieve a good defoaming effect. The addition of defoamer is generally divided into two steps, one is the grinding stage, that is, it is added during the adjustment and dispersion of the raw materials, and the other is the addition of defoamer in the canning stage. At this time, the defoamer mainly plays the role of suppressing foam. It suppresses the formation of foam during the construction phase.
Disinfectant for water-based adhesives-E-157: used in adhesive manufacturing, polyvinyl acetate, casein, dextrin, acrylic acid, natural and synthetic latex (latex), gel and glue, high viscosity white Latex, glue, EVA emulsion, latex, emulsion polymerization, acrylic acid emulsion, adhesive, white latex, starch glue, polyvinyl alcohol emulsion, for defoaming and anti-foaming. All kinds of emulsions: acrylic resin, adhesive, white latex, polymer glue, water-based color paste, emulsion polymerization, waterproof coating, printing, synthetic emulsion
Features: It is widely used in the manufacturing process of various adhesives as a high-efficiency defoamer for adhesive systems. It is easy to disperse and easy to use. It has fast defoaming effect and foam suppression function in a wide pH and temperature range, can quickly eliminate foam, and has the effect of preventing foam regeneration. In all kinds of emulsions, it has strong defoaming ability, fast foam breaking speed, long foam suppression without rebounding, completely eliminates all kinds of large and small bubbles, and improves product quality. The high-efficiency defoamer has strong defoaming ability, long-lasting foam suppression, no pinholes, and no impact on product firmness.
Waterborne Adhesive Defoamer
