PU-305 Hydrophilic aliphatic isocyanate curing agent
type:
Hydrophilic aliphatic isocyanate curing agent based on hexamethylene diisocyanate for two-component systems for coating adhesives.
Features/Applications:
PU-305 is a crosslinking agent for water-based coatings. It is particularly suitable for use in civilian applications where it is ready to mix by shaking or hand stirring.
Even in pre-diluted conditions, the coating film is still transparent and bright. The mix ratio of mill base to hardener is typically 10:1.
