Mandolite 990 is a spray or trowel applied, epoxy basedintumescent compound which, when subjected to fire, expandsto form an insulating barrier. barrire isolante.

Mandolite 990 produces a monolithic coating able to withstandthe thermal shocks experienced in high intensity hydrocarbonfuelled fires, particularly jet fires.

Although the added applied weight to a structure is low,Mandolite 990 is very durable, with high impact and weatherresistance.

Mandolite 990 is used for application on offshore steel orconcrete structures, storage vessels and supports, risers, ESDVsand pipework. It is also used on pre-assembled units prior totransportation to site as well as to structures fire proofed aftersite erection.

The offshore oil and gas industries will benefit from the use ofMandolite 990.

Structures protected with Mandolite 990 have undergone fire resistancetests in approved independent laboratories to recognised standards.

The fire response of Passive Fire Protection materials (PFPs) is assessed infire tests that are intended to represent the effects of real fires, eitherhydrocarbon pool or jet.

In addition, PFP systems may be required to provide the followingrequirements:

1. protection against high momentum jet fires2. resistance to blast/explosion overpressures.

The ratings for PFP systems are based on furnace tests carried out to therequirements of:

BS 467: Part 20: 1987 (Appendix D Hydrocarbon Curve)ISO/DIS 834 ProposalDEN/NPD Interim Standard.

The Mandolite 990 System has been fully tested and has fire approvalcertification for structures and fire resisting divisions. Moreover, the systemhas demonstrated a favourable response to jet fires and resistance to blast.

Cafco International should be consulted for confirmation of compatibilityand suitability.

Primed steel, galvanised/metalised steel, concrete structures, divisions andvessels.

To ensure optimal durability and corrosion performance, surfaces to becoated must be properly prepared and primed with a suitable primer.

Client company standards may form the outline specification.

It is the responsibility of the application contractor to confirm compatibilityand suitability of the primer system.

Fire tests conducted have been carried out with mesh reinforcement, todemonstrate the abiity of Mandolite 990 to stay in place under the mostsevere fire conditions.

Mesh retention may be based on one of the following options:
