Paint aluminum silver paste itself has highlights, bright, matte and other types, customers may not be as proficient as our aluminum silver paste manufacturers so clear and so fine, can show so much hue not only with the characteristics of aluminum silver paste, but also with dispersants, resins, auxiliaries and other raw materials, this article focuses on the analysis of the impact of dispersants (thinners) on coatings.
Many people think that the dispersant is only diluted aluminum-silver paste, which has no effect on the performance of the paint film. It is used casually during construction, no matter the diluent of primer or topcoat is mixed. There is an individual emphasis on the separate use of primer thinners and topcoats, but do not distinguish between manufacturers or fast-drying thinners. In fact, when making paint, there is still a lot of attention to aluminum and silver paste. 1. The diluent is divided into fast drying, standard drying and slow drying. Choosing the appropriate drying speed can increase the gloss of the paint adjusted by aluminum-silver paste. Paint manufacturers will automatically provide thinners with different volatilization rates in different seasons. Many manufacturers will separate the fast and slow drying thinner packaging and marking, professional differentiation and use, which provides a great adjustment space for on-site construction. 2. The thinner with strong solubility will appropriately increase the luster of the paint. the function of the diluent is to dilute the aluminum-silver paste paint, reduce the viscosity, and make the aluminum-silver paste paint achieve the required viscosity and the best construction effect. 3. The effect of diluent on paint gloss. Too much diluent will reduce the gloss, mainly due to the addition of too much diluent, the paint solid content decreases, the dry film becomes thinner, the paint surface is not full, resulting in low gloss.
4. Improper selection of diluent will also cause the following disadvantages of paint film:
Loss of gloss: the gloss of the paint film is plump before drying, but lacks luster after drying or gradually disappears after the sun exposure. Orange peel: the surface of the paint film is uneven, similar to the appearance of orange peel and grapefruit peel.
Facts have proved that when choosing to mix the paint with thinner, how critical it is to choose the right diluent. A good diluent will directly affect the brightness of the paste, of course. Aluminum-silver paste itself also has good brightness, poor brightness, which also requires customers to use their own use, to choose the right aluminum-silver paste, the right diluent.
