FIRE PROTECTION

摘要

A fire resistant formulation for application to a metal substrate, especially a structural element used in construction, comprises a first polymeric material and an intumescent formulation. The first polymeric material is preferably a rubber. The intumescent formulation preferably comprises a phosphate polymer (e.g. ammonium polyphosphate), a blowing agent (e.g. melamine) and a carbon source (e.g. pentaerythritol and/or di-pentaerythritol).
