Waterborne Acrylic Modified Saturated Polyester Resin WL-187
Water Based Saturated Polyester Resins are oil free non-oxidizing
resins. These resins are intended to be crosslinked with amino
resins through their free hydroxyl functionality. Crosslinking can
be done with with melamines and urea resins. When properly
formulated, these resins can give very high quality industrial
finishes.
• Non yellowing, even at high temperature curing
• Good hardness development
• Excellent solvent and chemical resistance (over 100 MEK)
• Excellent adhesion in direct-to-metal applications

3, Product Properties:
Waterborne Thinnable Acrylic Modified Saturated Polyester.
Low VOC, high gloss and hardness, excellent flexibility and
fullness.
Good solvent resistance and hydrolysis resistance.
Excellent shear stability, can be grinded with dispersions
directly.
Good storage stability.
4, Instructions:
After neutralized by N,N-2 methyl diethanolamine, WL-187can be
diluted by water directly. The adding amount of amine takes 4-5% of
theresin. The product can be baked and cured with etherfied amino
resins. It is suggested that the amino resins should be added by
25%-35%(for solidresins).Our company has the matching catalyst
CATO1. The baking temperature is more than 140℃.
The PH value can be adjusted by N, N-2 methyl diethanolamine. And
the viscosity of aqueous solution will increase with the increase
of PH value.
5, Storage:
It is suggested that the product should be stored in a cool and dry
place at 0-40℃. The quality guarantee period is 1 year, and the
expired productscan still be used after passing the inspections.
6, Applications:
Decorative waterborne polyester amino baking coatings.
7, Note:
