LLEWELLYN RYLAND Polyester Colour Paste

Llewellyn Ryland Polyester Colour Pastes are available in a wide range of colours. They have been developed to blend easily into resin systems. The range of colours is based upon pigments carefully selected for colour fastness, opacity, heat stability and having minimum effect upon the curing characteristics of the final system.

Lightfastness is the chemical stability of a colour paste under long exposure to light.

We chose Llewellyn Ryland Polyester Colour Paste for it's excellent ratings on the lightfastness scale. Wentworth Plastics GRP building products will maintain their colour for years to come. More info on lightfastness and the “The Blue Wool Scale” can be found here.
