Water based acrylic emulsion factory1/20/2024 Therefore, when they are used in conjunction with other resins and additives, be careful not to demulsify and flocculate the outer coat by temperature, stirring power, or adsorption or reaction of additives. Water-emulsion resins are oily, and they must be wrapped by surfactants, that is, emulsifiers, before they can be dispersed in water. Water-emulsion acrylic resins and water-soluble (including water-dispersible) acrylic resins have different structures and different properties, so naturally they have different uses. It has excellent light resistance, weather resistance, non-yellowing, long-term high gloss performance, and has grafting, copolymerization and blending modification with other monomers and polymers to obtain excellent water resistance, chemical resistance, and stain resistance Corrosion resistance, etc., are widely used in many fields such as coatings, adhesives, inks, textiles and leather auxiliaries. The water-soluble resin is transparent, a true solution of molecular-level dispersion, and is in a nano-dispersed state. Water-emulsion type is heavy and oily, generally milky white. Therefore, its particle size and transparency are also between the former two. It depends on external forced power, such as high-speed stirring and dispersion, or ultrasonic waves to achieve water dispersibility. The amount of emulsifier added is small and the hydrophilic group is insufficient. Water-dispersible resin is somewhere in between the two. Water-soluble resin is realized by the self-emulsification produced by the hydrophilic group on the polymer chain. Water-emulsion resin is prepared by adding emulsifier. Water-based acrylic resins are generally divided into water-based emulsion type acrylic resins and water-based solid acrylic resins. Not only the appearance is different, but also the use and characteristics are very different.Īt present, some vague concepts have appeared in the society, and water-based resins are generally referred to as water-soluble resins. Many people think that this is the same resin, but it is not. In fact, water-based resins are classified according to their appearance, which can be divided into water-emulsion type, water-dispersible type and water-soluble type. The difference between emulsion type and water-soluble acrylic resin:
