Introduction
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.
CR 3400 is designed to be backed up with Ampreg 22 and Ampreg 26 epoxy laminating systems. Under certain
conditions it may also be used in conjunction with SP SE70, SE84 prepregs, ST70 and ST 95 SPRINT® systems.
CR3400 must be painted prior to water immersion.
