Oxazoline Group-Containing Water-Soluble Polymer: EPOCROS™ WS Series Oxazoline group-containing water-soluble polymer
- Applications
- Functions
Basic Information
EPOCROSTM is a reactive polymer with an oxazoline group on the side chain and is used as a cross-linking agent for water-based resins. Among the water-based polymers developed to address environmental issues and the increasing use of water-based products due to VOC regulations and desolventing, the EPOCROSTM WS series is a “water-soluble type” with the following structure.

Features and Properties
- Higher reactivity than water-based epoxy, melamine, blocked isocyanate
- VOC free (EPOCROS™ WS-300 and EPOCROS™ WS-700)
- High crosslinking density with a small amount added
- One-pack type with long usage time
- Improves water resistance, solvent resistance, heat resistance, and the strength of films, etc.
- Adhesion-imparting possible to PET, OPP, PVC, etc.
- Fast drying
- Low toxicity (Ames Test: Negative, Primary Skin Irritation Test: No irritation)

New Crosslinking Technology
A new technology of mixing and heating emulsions containing COOH groups with a specific neutralization ratio improves the reactivity of the functional groups and lowers the curing temperature from the conventional 100°C to 80°C.
