FPW has innovated a unique polymer technology which offers excellent potential. It is based on a matrix polymer reacted with a transitional metal. Semi precious metals can be carried on the backs of other cheaper metal matrix. The new polymer can be used across a wide spectrum of applications; not limited to coatings, composites, adhesives and textile. This polymer chemistry is novel and exclusively developed by FPW.
The new technology incorporates a novel matrix polymer which undergoes multiple endothermic transitions from solid to gaseous state over a substantial temperature range. The endothermic reaction corresponds with the sublimation and ablation reactions during intumescence process. This enables engineering of the mathematical model plateau. This chemistry has components which work as self generating catalysis and need minute amounts of catalyst for initiation

This test verifies the novel aspects of this new technology. The graph clearly depicts specific areas of the technology which have been incorporated into the formulation. This test is an example of the processes which we have incorporated into our development:
- The basic formulation design is dependant on the end requirements of the system to be tested. In this case it was to develop a specific formulation to have specific criteria of the coating, as well as offering an improvement in fire performance over the leading competitor product for the cellulosic fire regime, as stipulated in ASTM E119, BS 476 part 20,21.
The basic design of the formulation was conducted specifically for cellulosic fire regime, as determined in ASTM E119, BS 476 part 20,21. This bench formulation used the detailed knowledge of specific reaction kinetics and transitions which are understood by the various experts at FPW. These reactions and the formation the various transitions at specified external test temperatures are quantified using the bespoke thermal analytical equipment available at FPW. These detailed studies allow for the optimal use of the various chemicals to harness the required suppression of temperature growth within the steel substrate.

FPW has developed a theoretical model which takes into consideration the transition phases of the New Technology Using this model it is possible to derive the following.Expression relatingthe delay time (time taken for coating to exhaust itself) to various paint characteristics:
Et= c1Lo(To-Tr) + NLo+c2L1(Td– To) + Ec2L12/6k2
Hence we can relate the original thickness of the coating as applied; the final, fully expanded, coating thickness; energy radiated onto the coating; enthalpy change involved in the phase change; and the critical temperature and dangerous temperature.
