Crestafire® GCS 1001E PA Intumescent flame retardant gelcoat, spray application

Crestafire® GCS 1001EPA is a pre-accelerated, low smoke fire retardant intumescent polyester based gelcoat. It incorporates new intumescent technology and has been formulated for spray application. When exposed to fire, Crestafire® GCS 1001PA forms a foamed cellular charred layer on its surface, which offers protection to the whole composite. Crestafire® GCS 1001EPA is available in a restricted range of colours and is designed to be post-painted.

Formulation

Crestafire® GCS 1001EPA should be allowed to attain a working temperature between 23°C-25°C before use for best spraying application. Stir well by hand or with a low shear stirrer to avoid aeration and then allow to stand to regain thixotropy. Crestafire® GCS 1001EPA requires only the addition of a medium reactivity MEKP (50%) type catalyst to start the curing reaction. The catalyst should be added at 2.0% into the gelcoat and then thoroughly incorporated with a low shear mechanical stirrer where possible.

Certifications

Cured composite laminates manufactured with Crestafire® P1-3001PA and Crestafire® GCS 1001EPA gelcoat can achieve HL2 - R1/R7/R10/R17 classification according to European standard EN 45545-2:2013.

Resin caracteristics

The gel time of this resin at 20°C with 1% PMEC 50% catalyst is 15 to 25 minutes.

The deformation temperature under load (1.80 MPa) is 60°C when the resin is fully cured (see technical data sheet).
