Cafco MANDOLITE^® CP2 - Vermiculite Cement Based Wet Mix Spray

INTRODUCTION

Cafco MANDOLITE^® CP2 is a spray applied, single package factory controlled premix, based on vermiculite and Portland cement, for internal use.

Cafco MANDOLITE^® CP2 produces a monolithic coating able to withstand the thermal shocks experienced in a high intensity cellulosic fire. Concrete structures in particular, will be protected from explosive spalling when coated with Cafco MANDOLITE^® CP2.

Although low in density, thus significantly reducing dead load, Cafco MANDOLITE^® CP2 is highly durable and will not crack or spall under mechanical impact.

Cafco MANDOLITE^® CP2 may be applied within environments where limited exposure to the elements is likely throughout the building phase of the project, e.g. perimeter beams.

Cafco MANDOLITE^® CP2 is used for application to steel and concrete frames, metal floor or roof decks, and return air plenums. It may be easily removed and reinstated locally when additional fixings are required. Building types that will benefit from the use of Cafco MANDOLITE^® CP2, include a wide range of educational, leisure and entertainment centres, commercial or industrial projects.

ADVANTAGES

• Structures protected with Cafco MANDOLITE^® CP2 can provide fire resistance for up to 240 minutes.
• Does not release toxic or hazardous fumes.
• Presents no known health hazards either before, during or after application.

QUALITY ASSURANCE

Promat operates a quality system in accordance with BS EN ISO 9001: 2000 and has received full accreditation to these standards.

Operating to these standards means that all activities, which have a bearing upon quality, are set out in written procedures.

Systematic and thorough checks are made on all materials and their usage. Test equipment is subjected to regular checks and is referred back to national standards.

The information given in this data sheet is based on actual tests and is believed to be typical of the product. No guarantee of results is implied however, since conditions of use are beyond our control.

FIRE PROTECTION THICKNESS

The thickness of the fire protection for a given period of fire resistance in a cellulosic type fire, relates to the A/V ratio of the section.

All column and beam sections have their own specific A/V ratio. Please consult Promat to establish the A/V ratio for a particular beam or column section. TABLES 1 and 2 ascertain the thickness of Cafco MANDOLITE^® CP2 that meets the required period of fire resistance for I-section beams and H-section columns.

For advice on thickness calculations for hollow sections, cellular beams, castellated sections, composite floors, upgrading of concrete slabs and more complex situations, please contact Promat.
