Inorganic zinc paint crosslinking agent

Inorganic zinc paint crosslinking agent

The classification and construction considerations of inorganic zinc rich lacquer. The method can be divided into two types: one is self-solids, the other is the latter, and the other is the rear solid, which needs hot or crosslinking agent after construction. Generally speaking, the fixed type construction is convenient, and then the post-solid construction is treated with crosslinking agent, which is more troublesome, but the performance of self-solids is worse than the postfix.

Inorganic zinc rich lacquer is restricted by climate condition during construction, the quality of lacquer film is very sensitive to climate, so it cannot be constructed under cold and wet conditions. In addition, the coating should be treated strictly, otherwise the coating will not be old. The coating is acidic and alkaline, and as a primer, it should be coated with good acid and alkali resistance. The most commonly used paint is epoxy enamel or vinyl.

The performance of inorganic zinc rich lacquer is:

The film is strong and durable, not affected by atmospheric conditions and ultraviolet radiation.

Water resistant and salt-tolerant water, the coating has no change after 1 year of water, brine and salt fog, and its water and salt water resistance is good.

Oil resistant and solvent, the function of various petroleum products and organic solvents is stable.

4. Heat resistance, it can be 450 ℃ high temperature resistant.

Non-toxic and odorous, easy to operate and improve working conditions.

Based on the above characteristics, inorganic zinc paint can be used in the inner and outer wall of tank car, water tower, sink, heat exchanger, and can be used on the iron chimney.

By amino resin and alkyd resin made from amino alkyd resin as film-forming substances known as amino alkyd resin paint coating, alkyd resin as film forming material alone coatings alkyd resin paint.

The classification and performance of alkyd resin

According to the variety of oil:

(1) dry oil modified alkyd resin;

(2) no alcoholic acid resin.

According to the oil content:

Alkyd resin can be divided into long, medium and short oil degree.

The coating is dry and fast, the paint film is hard and shiny, and the adhesion is strong, which can be dissolved in xylene and turpentine. The paint of medium oil degree alkyd resin is good in dry, gloss, hardness, adhesion, flexibility, color and durability. The paint film is flexible, high gloss and outdoor durability, which can be dissolved with 200 # solvent.

Other alkyd resin

A variety of alkyd paint

External alkyd resin paint:

It is made of dry alkyd resin, which is self-drying coating.

The main characteristic of the paint film is that it is superior, flexible and shiny, which is suitable for the surface paint of large area steel structure.

General alkyd resin paint:

It is made from the dry and low-temperature drying of the dry and low temperature. Has a good outdoor durability, and has high hardness, strong luster, good flexibility, paint film is more beautiful, applicable to the construction of the doors and Windows, stair handrail, wall panels, etc.
