Application of resin
Using special care, apply the gelcoat resin by brushing on to the pretreated
surfaces. In the case of backfilling with carbon-fibre fabric in particular, only one
layer of the gelcoat resin - and then only a very thin one - should be applied as
otherwise there will be a danger of cracks occurring.

Handling
precautions
Caution
Ciba Specialty Chemicals’ products are generally quite harmless to handle provided that certain precautions
normally taken when handling chemicals are observed. The uncured materials must not, for instance, be
allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the
uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be
affected. The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of
eye protection. The skin should be thoroughly cleansed at the end of each working period by washing with
soap and warm water. The use of solvents is to be avoided. Disposable paper - not cloth towels - should be
used to dry the skin. Adequate ventilation of the working area is recommended. These precautions are
described in greater detail in Ciba Specialty Chemicals publication No. 24264/3/e Hygienic precautions for
handling plastics products of Ciba Specialty Chemicals and in the Ciba Specialty Chemicals Material Safety
Data sheets for the individual products. These publications are available on request and should be referred
to for fuller information.
