CR 3400 In-Mould Epoxy Gelcoat / Surfacing System


SP-High Modulus, the marine business of Gurit’s gelcoat solutions are used in a variety of applications in the marine, wind energy, automotive and tooling markets. They are offered with a range of hardener speeds so that they can be used on a variety of differently sized parts; from a dashboard moulding, up to wind turbine blades of over 40 metres in length. 


  •        Easy to sand

  •        May also be used with some Gurit prepregs

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.
