What's the Difference Between Epoxy Undercoat and Epoxy Zinc-rich Paint?

As we all know, epoxy paint is an anti-corrosion finish made up of epoxy resin adhesive, rust-resistant pigments, and amine hardeners, which can be widely used in marine, metal components, ships, steel frame structures, highway bridges, and other exposed components that can be spray painted to achieve the practical effect of anti-corrosion and rust prevention. Today we will explain the difference between epoxy paint and epoxy zinc-rich paint.

Epoxy Paint

It uses an active solvent thinner and toughening agent to complete the active solvent coating, and the key coating material is modified epoxy resin adhesive. It gives the coating excellent adhesive strength, excellent organic chemical reliability, and physical properties.

In addition to the excellent insulation performance and organic chemical reliability of organic solvent epoxy anti-corrosion coatings, epoxy paint has greatly improved adhesive strength, elongation, impact resistance compression strength, and tensile strength.

During construction, the active solvent coating evaporates, and the single coating thickness can reach above 200um without pinholes or drawbacks. It saves energy and protects the ecological environment.

The active solvent coating epoxy anti-corrosion coating has many advantages such as high compressive strength, high solid content, good corrosion resistance, simple construction process, and no air pollution. epoxy paint is mainly used in heavy anti-corrosion industries such as steel pipe anti-corrosion, buried pipeline internal and external anti-corrosion, repairing damages, bending pipes, and buried steel pipe anti-corrosion maintenance in large cities.

Epoxy Zinc-rich Paint

The zinc content in the coating of epoxy zinc-rich paint is high, the anti-corrosion characteristics are excellent, the adhesion is good, it has the function of cathodic protection of pipelines, excellent waterproof performance, good physical properties, and conductivity and the function of cathodic protection of pipelines.

A coating thickness of more than 75um can be used as a production workshop dipping finish. The thick coating of epoxy zinc-rich paint can be welded above 15-25um without disturbing the welding characteristics. This product can also be used as an anti-rust finish for various types of pipes and liquefied gas cylinders.

Tianjin Jinhai Special Coatings & Decoration Co., Ltd. have passed the ISO9001 quality management system certification and CCS factory certification of China Classification Society. The company's main technical personnel are from national research institutions, who have been focusing on the development of coatings and paint in the heavy anti-corrosion field for more than 20 years.
