Paint knowledge | the same barrel of matte clear finish, when it was first used, its luster was brighter, but later, its glossiness was lower and lower, until finally, it became all matte. What is the reason for this?

Core tip: answer: to solve this problem, first of all, we need to understand the composition characteristics of matte finish Generally, in addition to resin, solvent, additives and other basic components, there are extinction powder that determines the gloss of matte finish The matting powder is not dissolved in the paint Instead, it is dispersed and suspended in the paint as a particle The proportion of extinction powder after fully wetting is larger than other components Therefore, after storage for a period of time, extinction powder will settle slowly, and a large number of extinction powder will accumulate in the lower part of the whole barrel of paint The closer to the bottom of the barrel, the more accumulation of extinction powder When using paint, if not aligned Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: A: to solve this problem, first of all, we need to find out the composition characteristics of matte clear finish Generally, in addition to the basic composition of resin, solvent, additives, etc., there are also extinction powder that determines the gloss of matte clear finish The matting powder is not dissolved in the paint It is dispersed and suspended in the paint as a kind of particle The proportion of extinction powder after fully wetting is larger than other components Therefore, after storage for a period of time, extinction powder will settle slowly, and a large number of extinction powder will accumulate in the lower part of the whole barrel of paint The closer to the bottom of the barrel, the more accumulation of extinction powder When using the paint, if the whole barrel of paint is not stirred or stirred, but it is not enough, it will cause different content of paint extinction powder in different parts of a barrel of paint, or different content of paint extinction powder in different pour times In this way, when the whole barrel of paint is used at the beginning, its luster will be brighter, and the more to the bottom layer of paint, its gloss will be lower and lower Therefore, before each time the paint is taken from the barrel, the whole barrel of paint shall be fully stirred from the bottom to the surface with the mixing rod During mixing, it is not only to stir in the circumferential direction, but also to extract the mixing rod up and down while stirring in the peripheral direction The mixing rod shall be inserted at the bottom of the barrel before being lifted up to fully mix the sediment at the bottom of the barrel and the paint on the surface At this time, take out the paint for use and prepare the paint according to the required proportion Only in this way can the paint performance (including gloss, hardness, fullness and covering power) be kept consistent It is emphasized here that the precipitation of matte paint is absolute and non precipitation is relative A good matte paint is allowed to precipitate, but it is better to use it after it has been fully stirred and even If it is not placed for a long time, the extinction powder will sink to the bottom in a large amount and form a mass, which is seriously stratified After mixing, it is also difficult to be even, and it is difficult to paint the qualified effect, which is not the top grade 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,
