UV resistance

A pre-finished steel must resist the damaging affects of Ultra-Violet (UV) degradation where a deterioration in both the colour and gloss retention are precursors of paint degradation. Consequently the ability of a paint to maintain both colour and gloss are seen as indicators of the longevity of a paint system.

QUVA tests

Samples of Colorcoat Prisma® have completed over 6000 total hours in the QUVA test and both gloss retention and colour change assessed. Even after this extended testing period, Colorcoat Prisma® solid, metallic and matt samples have a colour change of less than 1 ΔE.

Following the tests, the complete colour range of Colorcoat Prisma® has been classed as Ruv4 in accordance with EN 10169:2009, the highest classification available, providing reassurance that your building will retain its true colour for longer. The results are given below:
