Epoxy asphalt anti-corrosion paint tells you that there are various types of polyurethane anti-corrosion paint, which can be suitable for many purposes. Two-component, room-temperature-curing hydroxyl-type polyurethane coatings are the main varieties of polyurethane anti-corrosion paints. Has outstanding weather and oil resistance. Epoxy asphalt anti-corrosion paint is formulated from epoxy resin, coal tar pitch, antirust pigments, additives, and modified amines.

Epoxy asphalt anti-corrosion paint products have fast drying, good adhesion, good flexibility, two-component packaging, and convenient construction. It has adjustable and excellent comprehensive properties, and can form both rigid and elastic coatings. It also has excellent toughness, wear resistance, and low temperature curing. The formula has wide adaptability, and it can be compounded with various resins and additives to improve performance, and it is also conducive to the preparation of various environmentally friendly coatings.
Epoxy asphalt anti-corrosion paint tells you that due to the volatility and reactivity of the isocyanate group (-NCO) component in the paint, full attention should be paid to the processing, transportation, storage, and construction of the paint. Composition of polyurethane anti-corrosion paint Polyurethane refers to a polymer containing urethane bonds in its molecular structure.
Epoxy asphalt anti-corrosion paint tells you that urethane linkages are formed by the reaction of isocyanate groups and hydroxyl groups. Therefore, the monomers of polyurethane resins are polyisocyanates and polyhydroxy compounds. There are two types of polyisocyanates, aromatic and aliphatic.
Epoxy asphalt anti-corrosion paint Because the former is cheaper and more reactive at room temperature, the former is mostly used in anti-corrosion paints, and the latter is rarely used. The latter is only used in topcoats with decorative requirements In order to improve storage, construction, and paint film properties, polyisocyanate monomers are often made into polyurethane-prepolymers or adducts containing free isocyanate groups.
