Description

Corrosion resisting paint without need of cleaning rust

The present invention relates to a kind of Corrosion resisting paint without need of cleaning rust, belong to coating composition class based on urethane.

The whole world is because the direct economic loss that metallic corrosion causes is very surprising, for example this loss of China just accounts for 4% of gross national product, considerably beyond because of fire, the loss summation that disaster caused by a windstorm and earthquake cause, thereby prevent corrosion of metal effectively, it is the important subject of various countries that high-performance derusting rust-proofing product is provided, though existing several on rust paints, but also exist rustless property relatively poor, cost is higher, and strong alkali-acid resistance does not have also will divide weak points such as priming paint finish paint.

The purpose of this invention is to provide good, the Corrosion resisting paint without need of cleaning rust of the good decorative effect of tool again of a kind of antirust, anti-corrosive performance.

The objective of the invention is to realize in the following manner, it comprises first, second two components, uses preceding two component packing, allocates evenly getting final product during use in proportion, is 100% with the total amount of Corrosion resisting paint without need of cleaning rust, and first, second two component mass percents are:
