The future market direction and product characteristics of polyurethane coatings

Polyurethane
paint
is a more common class of
coatings
, can be divided into two-group polyurethane coatings and single-group polyurethane coatings. Two-component polyurethane coatings are generally composed of isocyanate prepolymers (also known as low-molecular urethane polymers) and hydroxy resins, commonly referred to as curing agent components and main agent components.
there are many varieties of this type of coating, the application range is also very wide, according to the different hydroxyl-containing parts can be divided into acrylic polyurethane, alcoholic acid polyurethane, polyurethane polyurethane, polyether polyurethane, epoxy polyurethane and other varieties.
generally have good mechanical properties, high solid content, all aspects of performance are better. Is currently very promising a class of paint varieties. The main application directions are
wood coatings
automotive repair coatings,
corrosive coatings
,
floor coatings
, electronic coatings, special coatings and so on. The disadvantage is that the construction process is complex, the construction environment is very demanding, paint film is easy to produce ills. Single-group polyurethane coatings mainly have ammonia oil coatings, moisture-cured polyurethane coatings, closed polyurethane coatings and other varieties. The application surface is not as wide as the two-part coating, mainly used in
floor coating
, anti-corrosion coating, pre-rolled coating, etc. , its overall performance is not as comprehensive as the two-part coating.varieties of polyurethane coatings are called polyurethane varnishes.properties: polyurethane resin as the main
film-forming
coatings. It is often divided into five categories according to its composition and membrane formation: polyurethane modified oil coatings, moisture-cured polyurethane coatings, closed polyurethane coatings, catalytic cured polyurethane coatings and hydroxy-cured polyurethane coatings. This type of lacquer film is bright and plump, hard and wear-resistant, oil-resistant, acid-resistant, chemical-resistant and industrial exhaust gas, has good electrical properties, can be mixed with a variety of resins, can be adjusted over a wide range of formulations to meet different needs. Widely used in wood, automobiles, aircraft, machinery, electrical appliances, instrumentation, plastics, leather, paper, fabrics, petrochemicals and other aspects.

Global
coating network
understand that this type of coating varieties, the application range is also very wide, according to the different hydroxyl-containing parts can be divided into acrylic polyurethane, alcoholic acid polyurethane, polyurethane polyurethane, polyether polyurethane, epoxy polyurethane and other varieties, is currently a very promising type of coating varieties.
research and development of polyurethane paint in China began in 1956, but only in 1965 there was a small batch of commercial paint production. In 1971, it was first made into 1,6-hexacyanate, which opened up the research and application of adipose polyurethane paint. After the reform and opening up in the 1980s, the production line of isocyanate and polyether polyol was introduced, which solved the problem of raw material supply.Polyurethane coating applications and market prospects:
polyurethane coatings are mainly used in wood coatings, automotive repair coatings, anti-corrosion coatings,
floor paint
, electronic coatings, special coatings, polyurethane
waterproof coatings
and so on. The disadvantage is that the construction process is complex, the construction environment is very demanding, paint film is easy to produce ills. Single-group polyurethane coatings mainly have ammonia oil coatings, moisture-cured polyurethane coatings, closed polyurethane coatings and other varieties. Mainly used in floor coatings, anti-corrosion coatings, pre-rolled coatings, etc. , its overall performance is not as comprehensive as two-part coatings. Polyurethane coatings are widely used, in addition to the above-mentioned uses, acrylic polyurethane can be used as magnetic recording coatings, polyurethane for electrical insulation coatings, transparent elastic polyurethane as anti-fog coatings, etc., for the automotive industry, aviation, marine, construction, plastics, mechanical and electrical, petrochemical and other fields.
