The intersection between the antirust primer and the epoxy primer

Author:    Date:2017/10/17 16:01:28

Whether it is metal profiles or steel structures are inevitably painted in the surface of a layer of anti-corrosion anti-rust primer, the face of ever-changing external corrosive substrate, the actual coating process we have to choose the appropriate application according to the appropriate anti- Rust primer, the choice of primer for the general selection of excellent adhesion of epoxy primer as a primer product, but we often say that the anti-rust primer is not the same product, today I will elaborate on the similarities and differences between the two.

We often say that the anti-rust primer, including epoxy anti-rust primer, but the epoxy primer is not all anti-rust primer. Such as cement, concrete substrate surface, the surface is generally not smooth, and the surface associated with pores or cracks, the rust is naturally not much significance, then we have to brush with a closed effect of epoxy closed primer, So that the paint completely penetrated into the cracks and pores, the effective bonding, so that the whole base is more solid and durable.

1, have to meet the permeability, due to open space and twists and turns, did not meet the high permeability, it is difficult to fill to the extent necessary.

2, resistance to chemical dissolution of the effect. As the coating itself is in a chemical and solvent corrosion medium, the closure agent can not withstand the corrosion of these media, the closure is invalid.

3, in the anti-corrosion paint between the layers have a higher strength. That the closure agent is not due to mechanical effects and fall off or broken.

4, stable at the operating temperature. That is, the closure agent can no longer operate the temperature attack ablation, transpiration or differentiation and other physical changes.

5, can not be stained with anti-corrosion coating or matrix chemical or electrochemical reaction, in the working environment with the coating and the substrate to maintain chemical stability.

6, do not drop the coating or matrix metal function, if applied topcoat, it is necessary to chemically compatible with the finish.

7, when the coating for the food industry, the food should be non-toxic.

8, strong water resistance, do not absorb moisture. For metal-based substrate, in addition to the commonly used epoxy rust rust primer, epoxy iron red rust primer, epoxy zinc-rich primer etc., can be used In the underground pipeline corrosion and corrosion of epoxy coal tar pitch primer, there are used for the inner wall of the tubing epoxy glass flake primer, for stainless steel or galvanized sheet surface of the epoxy zinc yellow primer. These are epoxy primer, but it is not included in the ordinary words of the epoxy anti-rust primer.
