PD61

A hard glossy intumescent coating to upgrade particle boards to fire barriers and upgrade timber doors to fire doors

PD61 was originally designed:

to upgrade heritage doors to fire doors without disassembly
to produce fire barriers from particle boards

It provides a system of production of fully sustainable building panels particularly relevant to timber frame construction.

PD61, a highly evolved formulation is:

a two pack material designed for factory flow line application based on IIT polymer
can be made to cure in minutes at low bake
may be site applied to doors and their frames, though finishing skills will be required

PD61 formulation is:

largely finalised and has been tested in the Prometheus Developments indicative fire test furnace
able to produce a 60 minute fire barrier from a single sheet of 18mm particle board coated on one side

PD61 has been indicatively tested in the Prometheus Developments SBI simulator

it gives a clear Euroclass B
it activates with very little smoke
it activates below the pyrolisis temperature of the timber substrate
it significantly retards distortion of the fire barrier leading to enhanced stability of jointed structures

PD61 cures to hard sateen finish that may be easily overcoated and decorated. Upon activation in a fire PD61 will intumesce through the decorative layer.

Exploitation

Prometheus Developments is seeking a collaboration partner that has a strong interest in either of the applications for this product. Terms are entirely flexible and open for discussion.
