For composite parts several surface colors and surface effects are possible. In principle almost all of these surfaces can be made graffiti proof by the selection of special grade gel coats (in mould coating) and paint systems. 

Fire retardancy

Concerning fire retardancy requirements a careful selection has to be made between surface systems. For the highest classes of fire retardancy (near class 0) gel coats can not be used anymore due to the high demands in smoke development. Only special phenol surface pastes combined with special paint systems will meet these high demands.

For all other fire retardancy classes up to class 1, special modified gel coats can be used. These gel coats are modified in such way that they have an extreme low smoke development in case of a fire and will bond to a phenol laminate under all conditions.

Colors and surface effects

Phenol surface pastes / Paints systems;   Surface pastes have a limited color range because paints systems are normally used for the final finish of a part. The color range can be seen on the website of Caleb Technical Products and consists of approx. 9 basic colors. The color ranges for the paint systems are up to your choosing according British Standard, RAL Standard and RAL metallic standards. The finish itself can be textured (several grain levels), dull, silk gloss and high gloss.

Special modified gel coats; The color range for gel coats are normally according the RAL and BS color range standards. Other colors can be mixed but for this a minimum amount is required. The possibilities with gel coats are enormous. Some are;
