Two component isocyanate cure acrylic resins WL-157
WL-157 is two component urethane coatings that have superior color
and gloss retention. These products are usually used as topcoats
and have good hardness and adhesion, acid, alkali, impact and
abrasion resistance.It`sused to replace the standard solventborne
polyurethane tested.
- Excellent color and gloss retention
- Excellent flexibility
- Good abrasion and chemical resistance
- 2 component
- Application: Brush, Roll, or Spray

3, Product Properties:
Self emulsifying process, emulsifier free.
Excellent shear stability, can be grinded with dispersions
directly.
Quick-drying,Good gloss, hardness and limit film thickness.
Excellent weather resistance, water resistance and aging
resistance.
4, Instructions:
WL-157 can be diluted with deionized water to construction
viscosity. The resin can help to wet pigments, so wetting agent may
reduce PH valueof the coating system can always be adjusted by N.
N-dimthylethanolamine, viscosity of the dispersion will increase as
the PH value increases
WL-157 can be mixed with poly aliphatic isocyanate curing agent for
preparing high-gloss top coating which can dry fast at room
temperature ordry by force at 80"C. The activation period is about
3 hours if it is used with BAYHYDUR 304(NCO/OH=1. 4/1.0).
Construction equipments can be cleaned by water, alkaline detergent
or water soluble solvent.
5, 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 expiredproducts can still be used after passing the
inspections.
6, Applications:
2KPU self-drying top coatings and amino-baking top coatings.
