Thick & Thin Film Intumescent Passive Fire Protection

Wilson Industrial Services have been successfully engaged by clients providing solutions and passive fire protection services for both thick and thin film applications.

Passive Fire Protection products initially developed for the burgeoning offshore fabrication market during the 1980’s have evolved for use into fabrication and construction projects wherever there has been a demand for asset protection for hydrocarbon fire scenarios. This technology was further adapted for other likewise civil construction markets requiring asset protection for cellulosic fire scenarios.

Epoxy intumescent coatings, subliming intumescent coatings, cementitious, vermiculite, shotcrete, gunnite, removable panel systems for structures, enclosures for ESDV, pipework flanges and jacketing systems, pre-cast and moulded components, syntactic insulation, cryogenic spill protection and thermal insulation, penetration seals. All successfully delivered by Barrier Fire Protection to some of the highest compliance standards developed, Lloyds Register, Det Norske Veritas, International Maritime Organisation, Factory Mutual, Underwriters Laboratory, Loss Prevention Council amongst many additional client specifications and Global Standards.

Our SSPC Fireproofing Inspectors are qualified to deliver Quality Assurance to your PFP projects.

Types of Fire Protection

There are two basic types of fire protection: active and passive. Active fire protection includes alarms and detection systems, sprinklers and water deluge systems, firefighting equipment and foam and powder extinguishers. Passive fire protection (PFP) involves components of structural methods and materials such as concrete, low-density cement, mineral fibre boards, vermiculite cement and ablative and intumescent coatings. Intumescents are often referred to as thin-film or thick-film coatings.

Thin-film coatings can be solvent or water-based products and have dry film thicknesses (DFTs) of less than 5,000 microns (200 mils) or 5 millimetres (0.2 inch).Thick-film coatings are typically solvent-free, epoxy-based with DFTs of up to 25,000 microns (1000 mils) or 25 millimetres (1 inch).
