Instructions
WL-109 can be diluted with water after neutralization by N
N-dimethyl ethanolamine the amount of which is about 4-5%of WL-109
.It has to
combine waterborne amino resin to make baking coating. The
suggested amount is about 20-30% of YG-GR202 by weight. The baking
temperature
is above 120. The baking conditions and film properties are related
with the amino resins used. Right amount of waterborne acidic
catalysts can
be added when using methyl etherified amino resin recommended
adding amount is 0.5-1% of WL-109), which can accelerate
solidifying
PH value of the coating system can always be adjusted with organic
amine or ammonia. Viscosity of the dispersion will increase as the
PH value
increases. The resin can help to wet pigments, so wetting agent may
reduce
Storage:
It is suggested that the product should be stored in a cool and dry
weak alkaline place. The quality guarantee period is 6 months and
the expired
products can still be used after passing the inspections
Applications
Amino-baking top coatings
