Paint formulation: Determination of the ratio of pigment to base in latex paint formulation

Core tip: in the formulation of exterior wall emulsion paint, the design of the color base ratio must first consider the adaptation to the weather resistance of the coating Secondly, the permeability and water resistance of the coating should be taken into account In general, the ratio of Pigments / fillers to emulsion polymers (according to solid mass gauge) is 1.8~3.2, and the better choice is 2.3~2.8. When the pigment concentration is about 35%~45%, the coating's resistance to pulverization and color retention should be better At the same time, the tide in the bottom is not expected to damage the coating in the process of penetration and escape Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: the design of the ratio of color to base in the formula of exterior wall emulsion paint must first consider the adaptation to the weather resistance of the coating Secondly, the permeability and water resistance of the coating should be taken into account In general, the ratio of Pigments / fillers to emulsion polymers (according to solid mass gauge) is 1.8~3.2, and the better choice is 2.3~2.8. When the pigment concentration is about 35%~45%, the coating's resistance to pulverization and color retention should be better At the same time, the tide in the bottom is not expected to damage the coating in the process of penetration and escape If the ratio of pigment to binder is too high, the interface of pigment and binder will increase If it is not to improve the covering power of the coating, the increase of the interface is not good for the rheological property of the coating, and it may also reduce the stain resistance and wash resistance of the coating, and accelerate the pulverization tendency of the coating, so it is not advisable If the color to base ratio of the formula is too low, the anti pulverization and color retention of the coating can be improved, the scrub resistance can be improved, and the density of the coating can also be increased, which may hinder the escape of the moisture in the substrate Once the steam pressure generated by the moisture is greater than the adhesion of the adhesive to the substrate, the coating will bubble, which is a disease of the coating and should be avoided 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,
