Xylene Two Component Polyurethane Coating , Alkyd Based Enamel Paint 10 MgKOH/G

Two Component Polyurethane Coating use

These paint films are bright and full, hard and wear-resistant, oil-resistant, acid-resistant, chemical-resistant and industrial waste gas. They have good electrical properties and can be mixed with various resin esters. They can be adjusted in a wide range to meet different needs. Widely used in wood, automotive, aircraft, machinery, electrical appliances, instrumentation, plastics, leather, paper, fabrics, petrochemical and other aspects.

China's high-grade coatings for wood products mainly include polyurethane paint (PU) and polyester paint (PE).

1. Polyurethane paint (PU): PU is divided into single component and two component, one component urethane oil and urethane alkyd. There are many types of PU, and the market is mainly a two-component hydroxyl-curable PU.
2. Polyurethane paint (PU): anhydrous xylene, anhydrous cyclohexanone or anhydrous butyl acetate polyurethane paint (PU): anhydrous xylene, anhydrous cyclohexanone or anhydrous butyl acetate
3. Solid content polyurethane paint (PU) category: 40-70%
4. Construction time limit (coating period, active period) polyurethane paint (PU) category: 4-8h
5. Curing conditions and mechanism Polyurethane lacquer (PU): It can be dried at room temperature or at low temperature (50 °C). The solvent in the coating is volatilized, and an addition polymerization reaction occurs between the isocyanate-containing component and the hydroxyl group-containing component to form a film.
6. Hygienic conditions for construction Polyurethane paint (PU): It is a solvent-based paint. It contains 30-60% organic solvent. It needs to be volatilized after painting. It pollutes the environment, is toxic and odorous, inflammable and explosive, needs to be ventilated and harmful. The national standard for volatile substances (volatile organic compounds, benzene, toluene, xylene, TDI and heavy metals) is limited by GB18581-2001, "Limits of Hazardous Substances in Solvent Coatings for Interior Decoration Materials".
7. Drying time polyurethane paint (PU): surface drying 15-20min, grinding 3-4h, solid drying <24h
8. Recoating polyurethane paint (PU): It can be dried or wet.
9. Performance polyurethane paint (PU) class: paint film with excellent comprehensive physical and chemical properties

PU paint 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.
