G P COLOUR SYSTEMS
General
G P Colour surface coatings systems possess many desirable
properties which are not found in other more conventional
air drying or stoving coating materials. G P Colour coatings
dry and ultimately cure by virtue of the reaction which takes
place between the two components (Base colour and activator),
when the two are mixed together. The linkages so formed by
this reaction give a very stable high polymer which is resistant
to breakdown under severe conditions.
The range of finishes produced under the name
G P Colour has been developed for
applications to all kinds of substrates, woods, metals, concrete
etc and provides high gloss,
high build, high performance pigmented finish of great hardness,
toughness and abrasion
resistance.
The outstanding characteristics of G P Colour are really mechanical
properties such as hardness, flexibility and toughness, scratch
and abrasion resistance.
Combined with these features are excellent resistance to corrosion
and also to water and aqueous solutions of many acids and
alkalis. Resistance to heat of G P Colour is also very good,
up to 250º C (482ºF) and although discolouration
may be expected on prolonged exposure at this temperature,
the film does not fail.
Furthermore, whilst G P Colour is not completely non flammable
in cured films, at the same time it does not assist the spread
of the flame.
The properties of Activator (this is the chemical cross-linking
agent) is important and has been carefully worked out to give
extreme hardness and flexibility together with high degree
of resistance to chemicals and corrosion. Thus it follows
that when the two parts (Base and Activator) are blended in
readiness for application, the instructions regarding mixing
should be followed without variation, incomplete mixing in
of the Activator (for
instance) could lead to uneven cure throughout the film.
