Dupre Minerals


A KEY DEFENCE AGAINST STRUCTURAL FIRES

A range of high performance flame retardant additives that can be mixed with established water based emulsion paint systems to upgrade fire retardant properties. Suitable for flammable and non flammable substrates.


DM875 is currently under development and is a passive fire retardant coating designed to achieve BS476 parts 6-7 and EN13501-1 on a Flammable Substrate such as Particle Board / Plywood or Plaster Board previously coated with multiple coats of Solvent based paint (typically 10-14 coats), the current most common practice is use an intumescent base coat beneath an FR Decorative Paint.

Intumescent paints pose several problems in that they are heavy coating thicknesses of typically 2.5 m2/litre verses conventional paints of 12 m2/litre, intumescent commonly contain substances that are not environmentally friendly and most of all they can be expensive due to the high paint cost and the low coverage rates.

In order to achieve BS476 parts 6-7 and EN13501-1 on Flammable Substrates using the Dupre range of FR Products it is also necessary to utilise a base coat system beneath the Dupre DM880 FR Paint such as Dupre DM875. DM875 base coat is water based, environmentally friendly and has a coating thickness of 12m2/litre.

Two coats of DM875 were applied at 12m2/litre on top of 10 coats of solvent based paint and then over coated with two coats of DM880 Decorative FR Paint at 12m2/litre in the below tests.
