PU Modified Alkyd Resin Introduction

PU paint is a general term for all polyurethane coatings. Its film formation is natural film formation, no special process is required.
Polyurethane paint is a two-component chemical structure:
A component (curing agent) of isocyanate group (-NCO) + ethyl component (lacquer) hydroxyl (-OH) = polyurethane
High polymer (paint film) thinner (Tian Na water): only adjust the viscosity, easy to dilute the construction.
Composition: main agent + curing agent + thinner

Characteristics

1. Chemically dry, operate according to the ratio.
2. Good overall performance; good hardness, good fullness, good adhesion, good durability and good hand feeling. The paint film is not very thin, but its adhesion is particularly good (even the wood with high oil content of teak can be used, not to mention the other); its gloss is said to be not very bright, it can display the floor very well. Spinning and color.
3. There is a certain period of use after the match.
4. PU paint is currently widely used in industry and construction, so the technology is mature, the color system is many, and it is easy to meet the spraying requirements. However, due to the harmfulness to the human body, the requirements for the spray booth and the paint booth are high, and at the same time, human body protection measures are required.
