A hybrid epoxy adhesive solution blocked with cashew nutshell liquid – a renewable blocking agent
Copied to clipboard
While hybrid technology is not new to the world of adhesives and sealants, only today’s solutions can combine optimal properties with ease of use. Hybrid epoxy and urethane systems offer an innovative solution for adhesive and sealant formulations. Desmocap® 14 CNB is a low viscosity, blocked TDI prepolymer that uses a renewable blocking agent – cashew nutshell liquid – making it a partially bio-based solution for toughening epoxy adhesives and improving physical properties. This high-performing material is especially suited for use in adhesive and sealant formulations for construction and industrial applications.
Desmocap® 14 CNB Properties & Benefits
Resins in the Desmocap® portfolio improve epoxies’ cure profile and physical properties in three ways:
Increased hardness, tensile strength, and tear-resistance to the epoxy, i.e. increased toughness
Faster green strength builds for adhesive formulations
Improved adhesion of epoxy adhesives through increased toughness and reduced brittle failure
Unlike previous generations of tougheners, Desmocap® 14 CNB achieves these benefits without a significant effect on the viscosity of the epoxy formulation.
Desmocap® 14 CNB improves strength and reduces the cure time of epoxy adhesives. It provides a unique advantage in lower viscosity of both the product and formulations made with it.
