Sustainable Clearcoat Formulations With an Extended Cure Window to Address Audi EV Needs

Abstract

With the higher demand in electric vehicles and the higher mass/stiffness of the rocker panel area to protect the batteries in a crash, an extended cure window is evaluated in a feasibility study.

A 2K clearcoat formulation made with novel Polyol Resins was evaluated with melamine types of different reactivity to address the extended cure window while meeting OEM specification.

Specially maintaining car wash and chemical resistance behavior in under curing conditions and physical properties like stone chip and steam jet in over curing conditions.

Eastman’s unique recycling technology allows this formula to be made at a 25% recycled content.

We have seen that a variant with a specific melamine worked best and a 50/50 mix with a commercial control showed performance meeting one of the Premium OEM specifications for the full extended curing window.
