CR 3400 is an in-mould epoxy surfacing system for epoxy laminates, and is designed to be used as the base for the subsequent application of a paint scheme. CR 3400 is therefore formulated to be easily sandable so that once released, the CR 3400 surface can be readily keyed prior to the application of the paint system. This feature gives additional benefits in that any minor surface defects caused by laminate print-through or mould imperfections can easily be sanded away.
CR 3400 is applied into a mould in the same way as other epoxy gelcoats, and has similar handling characteristics. However, the product has a considerably longer overcoating window than other gelcoats – up to one day with standard hardener at 20°C. This means that the system can also be used in a very flexible manufacturing environment.
