ARADUR® 2978-1

ARADUR® 2978-1 hardener is a low-viscosity, non-blushing epoxy curing agent with excellent handling and surface appearance properties. It can be formulated with modified or unmodified bisphenol A and bisphenol F-based liquid epoxy resins. ARADUR® 2978-1 is designed for two-component, ambient curing coating and flooring systems that require good esthetic properties, as well as good blush and early water spotting resistance. Its unique combination of long pot life and fast cure offers a distinct advantage over typical curing agents based on cycloaliphatic polyamines, such as isophorone diamine. The overall improvement in performance properties gained by using ARADUR® 2978-1 makes it an ideal curing agent for many applications.
