Waterborne Chlorinated Polyolefin

Recently, developing waterborne paints and adhesives has been required from the stand point of environmental concerns such as the VOC restriction. SUPERCHLON® waterborne grades developed with our special technology are able to meet these requirements. It can be used as a primer for polypropylene(PP) substrates, waterborne ink and adhesive applications.

General Features

1.Good adhesion to polypropylene (PP).
2.Provides equivalent performance to solvent-based grades.
3.Good storage stability.
4.Can be easily diluted with water.
5.Good freeze-thaw stability.

Results
Primer	E-480T	930
Adhesion	100/100	100/100
Gasoline resistance	more than 120 minutes	more than 120 minutes

Test methods
Adhesion	A cross-hatch adhesion test was performed after 24 hours. Cut 100 grid lines at 1 mm intervals reaching the PP substrate on the coating layer, perform a peel test with Sellotape, and count the number of remaining grid lines. (0/100= worst adhesion, 100/100= best adhesion)
Gasoline resistance	Cut an X mark reaching the PP substrate on the coating layer. Dip into regular gasoline under room temperature. Measured the time until the top coat are peeled off more than 3 mm. (Fail: less than 2 hours, Pass: more than 2 hours)
