ISOLATEK® Type M-IN/P(Worldwide)
CAFCOR FENDOLITE® M-II/P(Americas)
Industrial Spray-Applied Fireproofing
PRODUCT DESCRIPTION

ISOLATEK Type M-II/P is a single package, factorycontrolled Spray Applied Fire Resistive Material (SFRM) recommended for use in petrochemical facilities, refineries, and nuclear/power plants. Advanced Portland cement based formula provides increased density, enhanced bond strength and exceptional flexural strength. Developed and tested for fire protection of external structural steel components on or off-site) such as tanks, support legs and saddles, piperacks, vessel skirts, sphere legs, or interior situations where higher levels of abrasion resistance are necessary.

Description

PRODUCT ADVANTAGES
  • Tested to the latest industry fire standards (hydrocarbon and jet fire) including exposure to gas explosion and liquid nitrogen
  • Vermiculite aggregate provides excellent thermal resistance
  • Higher density and cohesive properties offers ultimate weather, abrasion, and erosion resistance, including high impact damage protection
  • Increased flexural strength for resistance to cracking, shrinkage, and spalling as well as for transportation of fireproofed steel structures
  • Reduced thicknesses provide required ratings with less material
  • Lightweight relative to concrete, lowering construction costs with savings in transportation and installation
  • Spray or trowel application allows for more options during installation

 

* Values represent independent laboratory tests under controlled conditions. Test reports available upon request.

+Value is provided based on Shore DO which more accurately represents a non-homogeneous product.

FIRE TEST PERFORMANCEISOLATEK

Type M-II/P has been extensively tested for fire endurance in accordance with industry specific protocols.

  • ANSI/UL1709 Rapid Rise Fire Test of Protection Materials for Structural Steel-UL Design XR725
  • ANSI/UL1709 Rapid Rise Fire Test as above however subjecting ISOLATEK Type M II/P to Two Full Scale UL 1709 Fire Tests within a 24-hour period (tested, allowed to cool to ambient and re-tested)
  • ANSI/UL1709 Rapid Rise Fire Test (following Liquid Nitrogen Immersion Test)
  • Gas Explosion Test (3 Bar Overpressure)
  • ISO 22899-1:2007(E) Determination of the Resistance to Jet Fires of Passive Fire Protection Materials
  • ISO 22899-1:2007(E) Determination of the Resistance to Jet Fires (following Gas Explosion Test)
  • NFPA 58, Annex H Procedure for Torch Fire and Hose Stream Testing of Thermal Insulating Systems for LP-Gas Containers
  • NFPA 290, Standard for Fire Testing of Passive Fire Protection Materials for use on LP-GAS Containers, standard and extended 150 minute tests
ENVIRONMENTAL TEST PERFORMANCE

In addition to the required ANSI/UL1709 environmental test conditions Aging, High Humidity, Industrial Atmosphere, Salt Spray and Combined Wet/Freeze/Dry Cycling, ISOLATEK Type M-11/P has also been evaluated under the following conditions:

  • Acid Spray – Exposure of the material (with and without topcoat) to a hydrochloric acid /water fog spray.
  • Solvent Spray – Exposure of the material (with and without topcoat) to a spray applied solvent for 5 cycles. Each cycle consists of the application of the solvent, 6 hour dry time, re-application of the solvent, and dry time of 18 hours.

  1. Spray-Applied Fire-Resistive Materials*
    – See table below for appropriate thickness. Prepared by mixing with water according to instructions on each bag of mixture and spraying in one or more coats, as necessary, onto the metal lath surfaces, which must be clean and free of dirt, loose scale and oil. As an alternate to spraying, may be machine mixed and trowel applied. Min avg density of 47 pcf (753 kg/m3), with min individual value of 43 pcf (689 kg/m3). For method of density determination, see Design Information Section, Sprayed Material.
  2. Metal Lath
    – For boxed and contour protection, min 3.4 lb. per sq.yd. expanded steel lath lapped 2 in. at joints and attached to column with power actuated fasteners and washers, spaced 18″ OC at overlap
  3. Steel Column
    – Min size of column W10x49.
  4. Corner Bead
    -(Optional – Not Shown) – No. 25 MSG galv expanded steel corner

bead with minimum 2 in. legs may be used in conjunction with column cage. When used, placed over each corner of column cage and attached to metal lath with tie wire spaced 18 in. O.C.
