water soluble epoxy resin,
waterborne epoxy resin
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:
● 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
Composition:Water based epoxy resin,cosolvent,neutralizing agent
Viscosity(mPa.s):150±50(at diluting ratio of 1:1,rotational viscometer)
Appearance:brown viscous liquid
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 ether,or clean water after passing the test.
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.
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.
