Water Based alkyd emulsion WL-0310
Water based alkyd resin WL-310 is a modified alkyd emulsion diluted
with water neutralized by ammonia, containing a small amount of
co-solvent. This product reduces the content of organic volatiles
(VOC) on the coating surface by mixing acrylic dispersions with
alkyd emulsion. Meanwhile, it combines the characteristic of fast
drying, yellow resistance of acrylic with the good film
performances of alkyd resin (including high gloss, excellent salt
fog resistance).
Due to good flow and levelling, coating made of WL-310 can be
applied by spray, roller, brush or dipping. It is recommended to
use in high performance protective coating and steel structure
coating for indoor and outdoor metal equipments, can be used as
primers and topcoats.
Features:
● Good storage stability,no ease to hydrolyze;
● Environment friendly product,VOC of less than 7%;
● Fast dry,and excellent gloss;
● This product contains drier,so it is unnecessary to add drier
during paint preparation;
● Excellent shear stability,and can directly use for pigment paste
grinding;
● Excellent anti-corrosivity,and good initial water resistance;
● The finished product paint has good versatility and good in-can
appearance,and can replace oil based alkyd anti-rust paint,alkyd
ready mixed paint,alkydenamel,etc

Instructions:
1. This product has excellent shear stability,and can directly be
used for pigment paste grinding.
2. Water based drier has been added to this water based alkyd
emulsion.The drier consumption is 5%-1%of solid content of the
emulsion.
3. It has good compatibility with other water based emulsions.
4. This product can be directly grinded with pigments and
fillers,but it is necessary to perform the compatibility test
because different acidic or basic pigment fillers may be used.
5. It has excellent rust resistance in the primer,especially under
action of antirust pigment.The best filler is talc powder or
kaolin.Calcium carbonate is avoided.
6. The finished product paint must be stored under alkaline
condition,at pH between 7.5 and 8.5.The pH value can be adjusted by
ammonia water,triethylamine or N,N dimethyl ethanolamine(DMEA).
7. Before use,the product can be diluted by deionized water.Tap
water can also be used after passing the test.
8. This product has high gloss and anti-corrosion performance,and
can be used for preparation of enamel,mixed paint and antirust
primer.
Storage
The product should be stored in a cool place below 38℃,and
protected from freezing in winter.Its shelf life is 6 months,and
the expired products still can be used if passing the inspection
