Multi Functional Acrylic Aliphatic Polyurethane Paint / Alkyd Oil
Acrylic Aliphatic Polyurethane Paint Introduction
Two-component polyurethane coatings have excellent film forming
temperature, strong adhesion, good wear resistance, high hardness,
good chemical resistance and weather resistance, and are widely
used as industrial protection, wood furniture and automotive
coatings. Waterborne two-component polyurethane coatings combine
the high performance of two-component solvent-based polyurethane
coatings with the low VOC content of waterborne coatings, making
them a research hotspot in the coatings industry. The aqueous
two-component polyurethane coating is composed of an -OH-containing
aqueous polyol and a -NCO-based low-viscosity polyisocyanate curing
agent, and its coating properties are mainly determined by the
composition and structure of the hydroxy resin.
Acrylic Aliphatic Polyurethane Paint Feature
- High decorative performance
- Performance diversity, adjustability. Through the improvement of
the formula, the polyurethane coating film can be made into a high
hardness coating film, or can be made into an elastic coating film
with excellent flexibility, which greatly enhances the application
range of the polyurethane coating.
- High temperature resistance and low temperature resistance.
- The film is non-toxic after curing.
- Environmentally friendly low voc coating
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
- Polyester lacquer is characterized by the formation of acyclic
and/or circular hydrogen bonds between polymer molecules. Under
external force, hydrogen bonds can be separated to absorb external
energy (20~25kJ per mole of absorption). When the external force is
removed, the hydrogen bond can be re-formed. Such a hydrogen bond
cleaves and re-forms reversibly, making the polyurethane paint film
highly mechanically wear resistant and tough. Compared with other
paints, under the same hardness conditions, polyurethane paint film
has the highest elongation at break due to hydrogen bonding, so it
is widely used as floor paint, overtime paint, high decorative
anticorrosive paint, and the like.
- Some varieties of coatings (such as epoxy, chlorinated rubber,
etc.) have good protection and poor decorativeness; some varieties
(such as nitrocellulose lacquer) have good decorative properties
and poor protection. However, polyurethane paint is both protective
and decorative, and can be used for the coating of high-grade wood,
piano, and large passenger aircraft.
- the paint film has strong adhesion. Polyurethane, like epoxy, can
be formulated as an excellent binder. Therefore, the coating film
has excellent adhesion to a variety of surfaces (metal, wood,
rubber, concrete, certain plastics, etc.). The author's experience
is that for some metal surfaces, the adhesion of polyurethane paint
is slightly inferior to that of epoxy paint; but for rubber, the
polyurethane paint exceeds the epoxy paint.
- 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
- 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.
- 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.
- 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.
- 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.
