Development trend of anti-corrosion coatings and coating technology

Anti-corrosion coatings are an important variety of coatings.

Pollution-free overall design of anti-corrosion coating technology

The so-called pollution-free overall design of anti-corrosion coating technology means that the various components of the coating itself (film-forming substances, anti-corrosion pigments, solvents and auxiliaries), the synthesis of raw materials, the coating production process, and the pretreatment of the substrate should be considered during the research and development.

Pollution-free or low-pollution water-based, high-solid, solvent-free and powder anticorrosive coatings

Water-based anticorrosive coatings: Inorganic zinc-rich coatings are an important variety of water-based anticorrosive coatings.

Ocean Chemical Research Institute adopts core-shell structure and self-emulsifying polymer emulsion manufacturing technology to develop nano-scale water-based acrylic modified alkyd latex, nano-scale water-based amino acrylic modified alkyd latex, water-based epoxy acrylic amino micro-latex, and these A series of water-based anticorrosive coatings prepared by latex have been used for anticorrosion in petrochemical, metallurgy, Wujinjiaodian, automobiles, rolling stock, trucks, ships and other fields.

Water-based coatings are more dependent on the construction environment.

Solvent-free and high-solid coatings with a volume solid content of 60% or a mass solid content of 80% or more are called high-solid coatings.

Spray Polyurea Elastomer Technology (SPUA) is a new solvent-free and pollution-free spray construction technology developed abroad in recent years to meet the requirements of environmental protection.

Powder coating: Powder coating is a kind of energy-saving, resource-saving, low-pollution coating, its utilization rate is as high as 95-99%, and it has developed rapidly in recent years.

High performance and multifunctionality of anticorrosive coatings

Silicone modified polyurethane, organic fluorine modified polyurethane coatings, fluororesin coatings and other high-performance coatings are another important aspect of the development of anticorrosive coatings.

Pollution-free anticorrosive pigment

Passivation or corrosion-inhibiting heavy-duty anti-corrosion coatings generally use the development direction of anti-corrosion coatings containing heavy metals such as chromium and lead.

Development of anti-corrosion primer for low treatment surface

In the anti-corrosion project, the construction cost accounts for more than 70%, and the surface treatment (rust prevention, oil removal, etc.

Strengthen the integrated quality management system of paint and painting

A complete coating technology development, construction and service management system is the basic guarantee for achieving the expected anti-corrosion goals.
