Epoxy coatings have strong adhesion, weather resistance, water resistance, durability and other properties. Generally divided into oil-based epoxy coatings and water-based epoxy coatings. According to their performance, there are generally wear-resistant epoxy coatings and epoxy anticorrosive coatings. Strictly divided into antistatic epoxy coatings and architectural epoxy decorative coatings. , The subdivision should be more precise in 4 categories.
Epoxy coatings are generally divided into two types: oil-based epoxy coatings and water-based epoxy coatings. According to their performance, there are generally wear-resistant epoxy coatings and epoxy anticorrosive coatings. Strictly divided, there should also be anti-static epoxy coatings and architectural environmental protection. Oxygen decorative coatings should be subdivided into four categories more accurately.
Epoxy resin and curing agent:
After the reaction, it is non-toxic and meets FDA non-toxic requirements.
Solvent:
For the dried coating film, the solvent volatilizes completely, no harm to the environment and human body.
Additives:
The amount of additives in the coating film is very small, and the non-toxic effect on the coating film is small.
Interpenetrating mesh wear-resistant coating
After curing, an interpenetrating network polymer anticorrosive layer between the epoxy resin chain and the rubber chain is formed, which effectively prevents the coating from changing and improves the weather resistance of the coating.
Good corrosion resistance
The coating also has strong adhesion, weather resistance, water resistance, durability and other properties.
Convenient construction
The construction process is simple, and it is not restricted by the site environment. It only needs to be used when it is used. The general construction method is adopted, and the film can be cured at room temperature.
Solvent-free epoxy resin sealing primer:
The cured product after the reaction of epoxy resin and curing agent is non-toxic and meets FDA non-toxic requirements.
Solvent-free epoxy intermediate coating mortar:
It is composed of epoxy resin and curing agent, quartz sand and quartz powder. The cured product after the reaction is non-toxic and meets FDA's non-toxic requirements; quartz powder and quartz sand are the products of crushed and screened natural minerals, non-toxic.
Solvent-free epoxy resin self-leveling floor paint:
1) Epoxy resin and curing agent: non-toxic after reaction, in line with FDA non-toxic requirements. 2) Additives: The amount of additives is very small in the coating film, and has little non-toxic effect on the coating film
Classified by construction method
There are epoxy coatings for spraying, epoxy coatings for roller coating, epoxy coatings for flow coating, epoxy coatings for electrostatic construction, epoxy coatings for electrophoretic construction, coatings for powder flow construction, and epoxy coatings for brushing.
Classified by purpose
There are architectural coatings, automotive coatings, wood coatings, machine coatings, sign coatings, electrical insulation coatings, conductive coatings, chemical-resistant coatings, anti-corrosion coatings, heat-resistant coatings, fire-resistant coatings, temperature-indicating coatings, lubricating coatings, ablation and heat insulation Coatings, food can coatings and flame retardant coatings, etc. In short, when classified by use, it can be summarized into three categories: construction, industrial use and special use.
Classification by curing method
Self-drying epoxy coatings: one-component, two-component and multi-component liquid coatings;
Drying epoxy coatings: single-component (or two-component) solid and liquid coatings;
Radiation curable coating: epoxy resin modified liquid coating.
Classified by name of curing agent
There are amine curing epoxy coatings, acid anhydride (or polyacid) curing epoxy coatings, ion-initiated curing epoxy coatings and synthetic resin curing epoxy coatings.
Classified by paint state
There are solvent epoxy coatings, high solids (less solvent) epoxy coatings, liquid solvent-free epoxy coatings, powder epoxy coatings and water-based (water emulsified and water soluble) epoxy modified coatings.
It is suitable for steel surface and anti-rust primer and workshop primer. It can also be used as bridge, ship, offshore platform, underwater coating, harbor facilities, automobile chassis surface anti-rust, oil tank outer wall anti-rust primer, and chemical industry Anti-corrosion coating, anti-corrosion coating of coal mine facilities, etc. Electrical insulation coatings, food can inner wall coatings, powder coating applications, etc.
①Waterproof treatment: The ground of the first floor must be waterproofed;
②Plain land treatment: Repair, polish and remove dust according to the condition of the prime land;
③Epoxy primer: A roll coat of epoxy primer with strong sealing and adhesion is used to enhance surface adhesion;
④Epoxy intermediate coating: Add epoxy resin to an appropriate amount of quartz sand, and coat it evenly with a trowel for several passes;
⑤Epoxy soil approved: According to actual needs, it shall be constructed several times, and the requirements shall be smooth and free of holes, no approved knife mark and sanding mark shall prevail;
⑥Epoxy topcoat: Two coats of solvent-based epoxy topcoat or anti-slip topcoat. After completion, the whole floor is bright and clean, with uniform color and no hollow drum;
⑦Completion of construction: You can get on board after 24 hours, and you can press hard after 72 hours. (25℃ shall prevail, and the low temperature opening time needs to be extended appropriately)
