Wood protection treatment

A single pack waterbased intumescent treatment for wood

The IIT polyol can undergo a further reaction to create a product that is an exceptional material for pressure impregnations and simple brush application to wood.

The material is supplied as a 60% solution with a surface tension lower than water. When the material dries out it produces a solid crystalline structure that is fixed into the wood species.

Indicative fire tests on our equipment show coating weights of just 130g/m² will provide protection to achieve a class 1 on the ASTM E84 and a Euroclass B on the EN13823.
