The closed primer is known as the "Hidden Master" ("Hidden Master: Closed Primer"), especially in water-based paint. If you choose the right closed primer, you can experience its power Features. Especially for the common drawbacks of wood tendons, mold, and yellowing, we need to use a special closed primer. Today we will specifically understand how powerful the closed primer is.

的 The importance of water-based coating closed primer 1. The closed primer can prevent or reduce the problem of water seepage, which facilitates the drying process to be smoother and prevents the phenomenon of tendons and mold;

2. Sealing primer can effectively seal the oil and tannic acid of wood, and reduce the trouble of painting.

Generally speaking, the use of solvent-based closed primer can achieve twice the result with half the effort; some factories with strict environmental protection requirements will require the use of pure water-based products for coating. In this case, the choice of water-based sealing primer It seems even more important!

How to choose water-based sealing primer The main function of water-based sealing primer is sealing, and the sealing performance is directly related to the water-based resin. The performance of water-based resins usually depends on the type of resin, the particle size of the resin, the glass transition temperature, and whether there is any special modification. These aspects are directly related to the performance of water-based closed primer construction performance and coating film physical and chemical performance.

Key performance indicators for water-based closed primer selection ▲ Permeability

▲ Water resistance

▲ Drying speed

▲ Closed

▲ Adhesion

The choice of water-based closed primer is mainly based on different furniture substrates and different requirements of furniture painting effects; for example, if the white coating effect is to choose a primer that has a unique sealing effect on tannic acid, the bathroom cabinet must choose water-resistant It is applied as a sealing primer with excellent properties.
