A question only becomes a problem if you don’t have a solution, we have many solutions, but if we don’t have one, we will develop one !

Colour

This is an area where WSL excel, we offer a very technical service, and we work closely with our customers in the development of bespoke, customer specific technologies, from the most basic to the most demanding of applications. The colour is only part of the formulation, the end use and production process of the customer are also extremely important, and every one of our formulations reflect this, in all our products. 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.

Additives and Foaming Agents

Since the 1980’s WSL has operated a powder blending, dispersion and distribution unit for a range of process additives, including chemical foaming agents and flame retardants. Additive technologies are often client defined and may include our FASCOM™ range of chemical foaming agents. This range has been developed over a number of decades with proven industrial success. The grades may be offered in single or multi – component format, tailored to optimise your overall performance, reacting synergistically with the base polymers and final processing demands.
