Water Based Hydroxyl Acrylic Resin
Water Dispersion Hydroxyl Acrylic Resin is two component PU resin,
Reacted with polyisocyanate, through baking, it can maximize
performance. water based hydroxyl acrylic dispersion can produce
the same hardness, impact resistance and solvent resistance as
solvent based polyurethane coating. coating made of these products
is recommended to use in topcoat of metal or wood due to its paint
film has excellent gloss, the construction method can be brushing,
roll coating or spraying.
main features:
● Water dispersible type, emulsion form hydroxyl acrylic resin
● High solid content, low viscosity, low acid value
● Mixed with isocyanate cross-linking agent to be two component PU,
has high gloss, high hardness
● Suitable for two component PU self-drying top coating and
amino-baking top coatings
Polyurethanes have excellent chemical resistance. They are hard,
tough finishes. They have chemical resistance, hardness &
resilience for substrates ranging from plastics of all types to
glass to wood to all metals, both primed & un-primed. These can
either be polyurethane lacquers, oil-modified polyurethanes or
two-component polyurethane systems.
Polyurethane materials are commonly formulated as paints and
varnishes for finishing coats to protect. This use results in a
hard, abrasion-resistant, and durable coating
Polyurethane varnish is capable of a much faster and higher "build"
of film, accomplishing in two coats what may require many
applications of oil. Polyurethane may also be applied over a
straight oil finish, but because of the relatively slow curing time
of oils, the presence of volatile byproducts of curing, and the
need for extended exposure of the oil to oxygen, care must be taken
that the oils are sufficiently cured to accept the polyurethane.
after evaporation of the solvent, upon reaction with oxygen from
the air, polyurethane coatings cure after evaporation of the
solvent by a variety of reactions of chemicals within the original
mix, or by reaction with moisture from the air.
