Waterborne Epoxy Resin for automobile chassis
WL-175 is a high solid mono-component resin, coating made by this
resin can produce hard, chemical-resistant, solvent-resistant
surfaces, has excellent water, alkali and acid resistance and
solvent resistance, used on various new or primed metal surfaces,
it has excellent rust resistance and corrosion resistance.
WL-175 is a self-drying resin, it is recommended for automobile
chassis, frame, suspension parts, advanced protective paint for
other engineering metals and equipments.
Water-based self-drying epoxy resin WL-175 has the following
characteristics:
- Durable water and heat resistance
- High gloss
- Excellent adhesion
- Good chemical resistance
- Excellent salt fog resistance
- High hardness
- Excellent shear stability, can directly participate in grinding
pigment paste.
Features:
● Acrylic modified;aging resistance>300h;
● Excellent shear stability,able to be grinded with dispersions
directly;
● Fast surface dry,quick hardness increase,and excellent anti-rust
property;
● Drying way:air dry oxidative cross-linking type;water based drier
is needed for making paint;
● Product form:solid content:75%;
● High solid content,lowviscosity,good anti-sagging property,single
spraying film thickness of above 50 micron
● Suitable for air-drying or low temperature baking type metal
anti-rust paint
Technical Index
Composition:Water based epoxy resin,cosolvent,neutralizing agent
Viscosity(mPa.s):150±50(at diluting ratio of 1:1,rotational
viscometer)
Non-volatile Matters(%)75±1
Appearance:brown viscous liquid
Properties:
Excellent anti-corrosivity,designed for the preparation of
anti-rust base coating;it can be made into air drying and low
temperature baking type antirust paint;the paint film has excellent
drying property and anti-corrosivity.
The product can be stored stably under weak alkaline condition,but
settles down under the acidic conditions,especially when acidic
pigment is added.Thus,the stable emulsion and lacquering shall be
stored under weak alkaline condition.PH value can always be
adjusted by triethylamine or ammonia water,and the emulsion
viscosity will increase as the PH value increases.
WQ-WL175 can be diluted with deionized water.When it is
diluted,acidic or impure water will instabilize the system.After
its pH is adjusted,the emulsion has good storage stability,can be
diluted with lower alcohol or alcohol ethe*,or clean water after
passing the test.
Instructions:
WQ-WL175 can be diluted with water to milky white emulsion,which
can be dried by oxidative cross-linking by adding solvent or water
based drier at normal temperature or baking at low
temperature.Beforeuse,the solvent based drier need to be diluted by
the solvent,such as butyl alcohol or ethanol.The consumption of
associated drier of this company is about 8%of the resin
consumption.The paint film dries very fast.The surface drying time
is about 20 min,and the hard drying time is about 4 h.After 24
h,the paint film has good strength.This product has excellent shear
stability,and can be grinded with dispersions directly.
Storage:
The product should be stored in cool,dry,ventilatedplace.The
quality guarantee period is 6 months,and the expired products can
still be used after passing the inspection.
