An analysis of the main features and construction methods of epoxy coatings

China Paint Online News Information
Epoxy coating is for epoxy heavy anti-corrosion coatings existing weather tolerance, easy to powder the deficiency, to the Chinese and foreign recognized long-lived chlorine polyethylene rubber as the main modifier, by adding special additives, additives, etc., prepared by advanced technology of the two-component heavy anti-corrosion coating., the main characteristics of epoxy coatings 1, mutual wear mesh wear coating. After curing, an interoperable mesh polymer anti-corrosion coating is formed between the epoxy chain and the rubber chain, which effectively prevents the change of the coating and improves the weather resistance of the coating.2, epoxy coating corrosion resistance is good. The coating also has strong adhesion, weather resistance, water resistance, durability and other properties.3, epoxy coating construction is convenient, room temperature curing. Construction process is simple, not subject to site environment restrictions, only need to use with the use of it, the use of universal construction methods, room temperature can be cured into a film.II, epoxy coating construction method 1, preparation method: first thoroughly stirred the paint to the bottom of the barrel without sediment, and according to the ratio of paint and curing agent 10:1 (weight ratio) special curing agent (winter temperature below 10 degrees C, according to the ratio of paint and curing agent 4:1 (weight ratio) added to the winter curing agent, fully stirred and cooked after 10 to 15 minutes. It's best to take a curing test first.2, surface treatment requirements: coating metal surface, blasting, blasting rust up to the international Sa2.5 level, after oil removal to carry out the necessary clean-up, keep the surface dry, and within 4 hours of coating, concrete coating, must be before coating air dry to water ≤10%, and clean the surface.3, use period: preparation of good paint, it is recommended to use in about 2 hours (20 degrees C) time, avoid the unused primer re-poured into the original paint material.4, coating thickness: high-pressure airless spraying, air spraying, dry film thickness of about 60 m, hand-painted, dry film thickness of 55 m.5, theoretical consumption: if the actual construction of the coating environment, coating methods, coating technology, surface conditions and structure, shape, surface area and other factors, the general consumption of primer volume of about 0.2kg/m2.6, coating method recommendations: In order to smooth the coating, it is best to use high-pressure airless spray, in the conditions of no high-pressure airless spray to choose air spray, manual painting as the third coating method to choose.7, diluent dosage: If the coating is really too thick, can be appropriately added special diluent, its dosage of 3 to 10%.8, tool cleaning: can be cleaned with special thinner. If the ambient temperature is below 10 degrees C, it should be extended appropriately.9, the last paint coating is completed, must be naturally cured 7 days before it can be put into use.
