A full colour matching service is available from our central research laboratory. For customers wishing to blend their own colours we offer the FASTINT™ range of mono-pigment tinters. We also supply products from our own FASCOL™ multi polymer range as well as many other internationally recognised ranges such as BS4800, BS5252, RAL840HR®, PANTONE®, NCS etc. We now have in excess of 37,000 formulations on our database, with 19,000 products currently active.
