ester-urethane resin dissolved in styrene.


BUFA-VE-Tooling-Gelcoat-H was especially developed for the
production of GRP moulds. The product is particularly suitable for moulds
that are subjected to high chemical and thermal loads.

Since the ability to pigment this class of resin is limited, it is essential that

only the pigmentations we offer are used. You should never tint with

untested pigments on your own.

Directions for use

BUFA-VE-Tooling-Gelcoat-H comes pre-accelerated and ready to use.

The gelcoat can be cured with standard MEK peroxides without having to

worry about the formation of foam typical for normal vinyl ester resins.

The first layer of gelcoat is applied by brush or roller in a layer 400-500

μm thick. After the layer has cured, a second layer 300-400 μm thick is

applied to even thinner areas and ensure uniform thickness.

Notes on release agents

Before the release agent is applied, make sure that the surface finish of

the model is completely cured. For release, we recommend the

application of 6-7 layers of BF 700 Carnauba Wax. Each layer of wax that

is applied should dry for at least an hour before the next layer is applied.

The completely treated model should be stored best overnight before

mould-making is begun. To ensure reliable release, the release wax

should be tested on a separate sheet first.


This product must be stored cool in closed containers, protected from

sunlight. Shelf-life is at least 3 months in unopened, original containers

stored up to a temperature of 20°C. Gel and curing times may change

with increasing duration of storage.
