EPOCROS™ WS-300 by Nippon Shokubai is a VOC-free adhesion promoter and waterborne crosslinking agent based on acrylic, high oxazoline functionalized reactive copolymer. The new crosslinking technology enhances the reactivity between oxazoline groups and carboxy groups through a heating and mixing process involving EPOCROS™ WS and a carboxy group-containing emulsion with a specific neutralization rate.
- It offers lower curing temperature, excellent storage stability, no peeling and long pot life for one packaging.
- It provides film properties, low toxicity, fast drying and improved water- & heat resistance.
- It shows excellent adhesion to polyethylene terephthalate (PET), oriented polypropylene (OPP) and polyvinyl chloride (PVC).
- It exhibits controllable appearance by glass transition temperature adjustment and crosslinking reaction at low temperature (80-120°C) with no by-product.
- It offers high reactivity and performance expression with even small addition.
- EPOCROS™ WS-300 is designed for coatings (metals, films, paper, plastics, leather), primer (film, plastics, building materials, automobiles, PVB inks), paints, inks and pigment printing.
- It is registered with CSCA(Japan) and TSCA(USA) regulations.
