Common problems with water-based lacquer wood paint: transparency, Color fullness of shade

The complaint that often hears about paint of ability in water is paint of ability in water diapure is poor, cannot show the plump godliness of woodiness. In general, the transparency of water-based paint is determined by the following several factors:

1.The transparency of the polymer itself

The best way to determine the transparency of the polymer itself is to apply the polymer to the heated black glass. The glass should be heated just above the minimum film forming temperature of the polymer so that  the polymer to cross-linked normally. In this way, the transparency of the polymer can be evaluated without the influence of other solvents and additives.

2.The use of solvents, additives and polymer mixtures will affect the transparency

Silicone additives have been shown to affect the transparency of certain polymers. On the contrary, wax emulsions are beneficial for transparency. Some solvents take a long time to evaporate in the lamine ine. They leave a small gap in the lamine hydroxylamine hydroxylamine when they evaporate, dispersing light and increasing opacity. Other solvents at the beginning of the hydroxylamine hydroxylamine hydroxylamine hydroxylamine has been dried, affect the transparency. However, these solvents will gradually evaporate. In this

process, the transparency of the film will increase. In the process of preparing a water-based paint, a thorough evaluation of the solvent should be made to determine which solvent will produce the system with the best overall transparency. A mixture of polymer with other polymer will because of particle size, reflective index, reduce the transparency and the incompatibility between the polymer to reduce the transparency of paint hydroxylamine.

3.A system with a high PH will cause the wood to appear "washed white"

To the woodiness that does not dye, can add a few red or yellow to catch makings in the first varnish, restore the red, yellow degree of woodiness itself. For stained wood. The use of substrate wetting agent can improve the color fullness of wood.Choosing the right solvent system for the varnish is the key to determining whether the substrate needs a wetting

leveling agent. Diacetone alcohol has some very interesting moistening properties.
