Two-component polyurethane coating Introduction


Polyurethane paint is polyurethane paint. It is strong in film, full of luster, strong adhesion, water resistant, abrasion resistant and corrosion resistant. It is widely used in high-grade wood furniture and can also be used on metal surfaces.

Characteristics of two-component polyurethane paint: Hydroxy-curable polyurethane paint has the advantages of being dry at room temperature, low toxicity, tough film, high gloss, good adhesion, corrosion resistance, oil resistance and water resistance. It is used in metal and cement. , wood and rubber, leather and other materials. Catalytic curable polyurethane lacquer coating has good oil, water, acid and alkali resistance, organic solvent resistance, and has good adhesion and wear resistance. It is generally used as a surface coating for wood, concrete, etc. Floor paint). Two-component polyurethane coatings generally consist of an isocyanate prepolymer (also known as a low molecular urethane polymer) and a hydroxyl-containing resin, commonly referred to as a curing agent component and a main component.

Two-component polyurethane coating advantage


  2. the elasticity of the coating film can be adjusted according to the needs of the distribution ratio, can be adjusted from the extremely hard coating to the extremely flexible elastic coating, while the general paint such as epoxy, unsaturated polyester, amino alkyd, etc. can only It is difficult to impart high elasticity by making a rigid coating.
  3. the coating film has excellent chemical resistance, acid, alkali, salt liquid, petroleum products, so it can be used as maintenance coating for drilling platforms, ships, chemical plants, and inner wall coating of petroleum storage tanks.
  4. can be dried at high temperatures, but also can be cured at low temperatures. In a typical room temperature curing coating: epoxy, polyurethane, and unsaturated polyester, epoxy and unsaturated polyesters are difficult to cure below 10 ° C. Only polyurethane can be cured at 0 ° C, so the construction season long. Because it can be cured quickly at room temperature, it can be used for large-scale projects such as large oil tanks and large aircraft to achieve better performance than ordinary baking varnishes.
  5. polyurethane paint can be made resistant to -40 ° C low temperature varieties. It can also be made into high temperature insulating varnish with properties close to polyimide.
  6. The electromagnetic wire coated with polyurethane paint can be used for automatic assembly of tin in molten solder without scraping paint. It is especially suitable for the assembly of telecommunication equipment and instruments.
  7. it can be combined with polyester, polyether, epoxy, alkyd, polyacrylate, cellulose acetate butyrate, vinyl chloride vinyl acetate co-ester, asphalt, dry oil, etc., according to different requirements Made into many varieties.
  8. can be made into solvent, liquid solvent-free, powder, water, single filling, two filling and other forms to meet different needs.

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 lacquer (PU): Adducts or pre-polyisocyanate groups of polyester, acrylic resin, polyether, epoxy resin (hydroxy-OH-containing component often referred to as main component or component B) Polymer (containing isocyanate-NCO component often called hardener or component A)
  2. Polyurethane paint (PU): 1-3 components, one-component, two-component, the latter also has a thinner when adjusting the paint, the general paint ratio is: main agent: curing agent: thinner is 1 :0.5-1:0.5-1.5
  3. Polyurethane paint (PU): PU is divided into single component and two component, one component urethane oil and urethane alkyd.

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



  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.
