Water
based resin includes water based acrylic resin, water based alkyd and epoxy
ester resin, water based saturated polyester resin, water based epoxy resin,
water based polyurethane resin and the so on.
Water
based acrylic resin: This type of water based resin has the largest production
outlet, the is most widely used. It can be polymerized with emulsion: the use of
emulsifier emulsification, polymer polymerization initiated in the water based emulsion, mainly used in interior and exterior wall paint, wood paint, plastic
paint and other industrial anti-corrosion paint and topcoats, such as coil
coating. Application features: good anti-sagging, fast drying, shine, poor
fullness, construction is easy to produce bubbles.
Water
alkyd and epoxy ester resin: a self-dry system, water anti-corrosion coating
has been widely used, such as automotive chassis, steel structure and other
industries have been quite mature.
Features:
Compared with the solvent slow drying, due to the neutralization of the role of
the polymerization of cross-linking oxidation is not very effective. At
present, many self-drying alkyd and epoxy ester applications are baking at
80-100 ℃. This kind of resin is used for baking paint, which can
make up the deficiency of self-dry cross-linking. It can be used in all kinds
of metal protection and decoration. Features: Because of such systems contain
oil molecules, the wetting of the paint is good, the film has excellent luster
and fullness, cost at the end.
Water
saturated polyester resin: This kind of resin is also through the salt-forming
mechanism of water, used in high-grade amino paint and coil coating.
Features:
This resin has excellent film hardness and processing performance, excellent
weather resistance and corrosion resistance, these products are now in volume
production, in the amino paint (electrostatic spraying) and coil coatings are
applied.
Water
epoxy resin: There are three water way: plus emulsifier, the use of amine
curing agent emulsion epoxy resin, epoxy molecules in the introduction of
hydrophilic groups. Such resins abroad a few years ago in the domestic
promotion, but in the drying time and the final performance there is a gap. In
recent years there are several domestic professional production of water epoxy
business, in the two-component epoxy anti-corrosion coating application has a
considerable scale.
