Epoxy phenolic paint film has good hardness and is suitable for wooden surfaces that do not collide indoors. Such paints are fast drying, hard film, durable, heat resistant, water resistant, weak acid and alkali resistant, and have a certain insulation capacity. The disadvantage is that the paint film is brittle, the color is easy to yellow and deep, and the weather resistance is poor.
Epoxy lacquers are a class of industrial coatings, and coatings containing more epoxy groups in the composition are collectively referred to as epoxy lacquers. The main type of epoxy paint is a two-component paint consisting of an epoxy resin and a curing agent. There are also some single-component self-drying varieties, but their performance is somewhat different from that of two-component coatings. The main advantage of epoxy paint is that it has strong adhesion to inorganic materials such as cement and metal; the coating itself is very resistant to corrosion; it has excellent mechanical properties, wear resistance and impact resistance; it can be made into solvent-free or high-solid coating; , heat resistant, water resistant; coating film is non-toxic. The disadvantage is that the weather resistance is not good. If the sunlight is exposed for a long time, there may be chalking phenomenon, so it can only be used for primer or interior paint; the decoration is poor, the gloss is difficult to maintain; the construction environment is high, and the film is coated at low temperature. The curing is slow and the effect is not good; many varieties require high temperature curing, and the investment in coating equipment is large. Epoxy resin coatings are mainly used in floor coating, automotive primer, metal anti-corrosion, chemical anti-corrosion, etc. [2].
The phenolic resin paint is a paint made of a phenol resin or a modified phenol resin as a main resin. Phenolic resin mainly replaces natural resin and dry oil to make paint. Because phenolic resin makes the coating have better performance in hardness, gloss, quick drying, water resistance, acid and alkali resistance and insulation. Therefore, it is widely used in wood, furniture, construction, electrical and other aspects. However, the phenolic resin can make the paint have a darker color, and the paint film is yellowed during the aging process, which is not suitable for the manufacture of light color and white paint.
