Portland cement based fireproofing formulated with bauxite and DCI requiring only the addition of water on site to form a consistent, pumpable and trowelable slurry. Weighing approximately 65–75% less than regular concrete, it can be applied at several thicknesses offering up to 4 hours hydrocarbon pool fire resistance.

It is not recommended in operating temperatures in excess of 93°C, for use over aluminium or other non-ferrous substrates, or use as a refractory material.

 

Features and Benefits:

 

  • Sets and dries to a hard, damage resistant coating offering resistance against physical impacts occurring during routine operations and maintenance at the facility.
  • It has been tested for bond, compressive strength, hardness and other properties in accordance with API RP 2218 and ASTM in place performance standards.
  • Can be mixed in standard plaster mixers. After mixing it may be spray-applied with commonly available pumping and spraying equipment for high speed efficient application. It can also be applied with trowels and poured into wood formworks.
  • Offers cost effective fire resistance in interior as well as exterior and corrosive environments such as those defined by ISO 12944-2 up to corrosion class C5-I and C5-M.
  • Low thermal conductivity.
  • Crack free formula.
  • Up to 25 mm per coat.
  • High yield rates.
  • Non flammable and non combustible.
  • Asbestos free.
  • Chloride and sulfide free.
  • No contribution to gas or smoke generation during a fire.

 

Has been tested in accordance with:

 

  • UL 1709 – up to 4 hours.
  • BS 476 Part 20 appendix D – up to 2 hours.
  • UL 263 – up to 4 hours.
  • Investigated by UL for exterior use even under freeze/thaw cycles.
  • Jet fire tested with HSE standard OTI 95634 – up to 2 hours.
  • Explosion tested to a charge of 227 Kg of TNT placed 19 meters away.
  • Tested under cryogenic conditions.

Applications
Not to be used if it contains partially set, frozen or caked material, can be sprayed directly to lathed steel substrates in one or more passes, a spray gun with a properly sized orifice with spray shield, and air pressure at the nozzle of approximately 20 psi (1,4 bar) will provide the correct adhesion, density and appearance temperature, An air and substrate temperature of 41°F (5°C) minimum shall be maintained for 24 hours prior to application, during application and for a minimum of 72 hours after application. To obtain optimal strength, Monokote Z-146PC should be moist cured for a minimum of 72 hours and then be allowed to dry naturally
BondStrength
Min 4,9 kg/cm² (0,49MPa)
CoatingPrimers
Has been formulated with a patented corrosion inhibitor (DCI) that has shown to retard the rate of corrosion due to chlorides and other aggressive environmental conditions, however Monokote Z-146PC shall not be used as an anticorrosive material, thus we always recommend the use of an alkaline resistant, immersion grade, epoxy anticorrosive paint (or system) compatible with Portland cemen
CoatingTopcoat
Generally not required, however in corrosive environments a compatible topcoat should be used to extend the life expectancy of the entire system, contact GCP Technical Service for further recommendations

HighVelocityAirErosion
No continued erosion after 4 hours
Mix
To be mixed by machine in a conventional paddle type mixer, the mixer shall be kept clean and free of all previously mixed material. The mixer speed shall be adjusted to the lowest speed which gives adequate blending of the material and a mixer density of 835 - 945 kg/m³
ResistanceToMoldGrowth
No growth after 28 days
Storage
The material shall be kept dry until ready for use. Packages of material shall be kept off the ground, under cover and away from sweating walls and damp surfaces, all material that has been exposed to water before use shall be discarded, stock of material is to be rotated and used before its expiration date
Yield
6,6 kg/m² at 10 mm
