Chemical Structure

Introduction

DP-186 is a clear colorless, low-odor liquid. DP-186 may be used as an adhesion promoter (coupling agent) for organic/inorganic interfaces, as a surface modifier (e.g. regulating surface polarity) or as a crosslinking agent (moisture-curing of polymers). When used as coupling agent, it generally reduces the sensitivity of the products' mechanical and electrical properties to heat and/or moisture.

Applications

DP-186 has a more reactive epoxy group when compared to the more common KH-560. This enhanced reactivity is due to the added strain put on the epoxy group by the presence of the second ring; the cyclohexyl. The increased epoxy reactivity combined with the greater organic character from the cyclohexyl group often results in enhanced mechanical properties and better wet-strength retention of properties when compared to KH-560.

DP-186 can be used to improve dry and wet strength in cured composites reinforced with glass fiber rovings.

DP-186 can be used to enhance wet electrical properties of epoxy-based encapsulate and packaging materials.

DP-186 can be used to eliminate the need for a separate primer in polysulfide and urethane sealants.

DP-186 can be used to improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings
