Cafco FENDOLITE®-MII

Advantages

  • Structures protected with Cafco FENDOLITE®-MII can provide fire resistance for up to 240 minutes.
  • Does not release toxic or hazardous fumes, and presents no known health hazards either before, during or after application
  • The surface may either be spray textured, roller or float finished

Cafco FENDOLITE®-MII is a spray applied, single package factory controlled premix, based on vermiculite and Portland cement. Cafco FENDOLITE®-MII produces a monolithic coating able to withstand the thermal shocks experienced in a high intensity hydrocarbon fire. Concrete structures in particular, will be protected from explosive spalling when coated with Cafco FENDOLITE®-MII. Although low in density, thus significantly reducing dead load, Cafco FENDOLITE®-MII is highly durable and will not crack or spall under mechanical impact. Cafco FENDOLITE®-MII is used for application on construction elements such as concrete or individual steel sections. It is also used extensively for the refurbishment or upgrading of existing tunnel structures.

Applications

Cafco FENDOLITE®-MII is used for tunnel adn oil & gas applications on construction elements such as concrete or individual steel sections. It is also used extensively for the refurbishment or upgrading of existing structures.

Properties and Performance

< #Back#
Acoustic Insulation

Noise reduction coefficient (NRC) 0.35

Alkalinity

12pH - 12.5pH

Corrosion Resistance Does not promote corrosion of steel. However, a primed substrate is recommended for long term corrosion resistance, particularly when the structure is to be fully exposed to the elements. See Preparation
Density

775kg/m³ ± 15% (when dry and in place)

Finishing May be floated or roller finished.
Fire Protection Thickness

Fire protection thickness requirements are often specified in the owner operator’s engineering codes of practice. Alternatively, please consult Promat Technical Department.

Full Cure By hydraulic set
Initial Set

2hourto 6hour at 20°C and 50% RH

Minimum Practical Thickness

8mm when unreinforced, 15mm when reinforced.

Theoretical Coverage

62m²/tonne at 25mm thickness

Thermal Conductivity @ 20 °C

0.19W/m°K

Top Coating Under certain circumstances, decorative top coating systems maybe used as protection from frequent wash down, long term chemical spills, or for improved resistance to fungal, algae and bacterial growth. Please consult Promat for details.

Substrates Preparation

The substrate shall be clean, dry and free from visible moisture (including condensation), concrete laitance, formwork release oils, loose mill scale, loose rust and any other condition preventing good adhesion. Concrete curing agents should not be used.

Typical Substrates Preparation

Concrete and steel

Application Initial Steps

Application of Cafco FENDOLITE®-MII must be carried out by an applicator recognised by Promat and applied in accordance with the installation guide available from Promat.

Application Limitations

Cafco FENDOLITE®-MII may be applied when the substrate and air temperatures are at least 2°C and rising, but should not be applied if the substrate or air temperatures are less than 4°C and falling. Maximum substrate and air temperature is 50°C. Substrate temperature should be at least 2°C above dew point temperature.

Application Method

Mix Cafco FENDOLITE®-MII with potable water in a suitable mixer and apply by a spraying machine approved by Promat. Cafco FENDOLITE®-MII may also be float or roller finished or left with a spray texture. Hand applied patching mix, Cafco FENDOLITE®-TG is available for minor repairs. Please refer to product data sheet of Cafco FENDOLITE®-TG.

Preparation Mesh Reinforcement

Most fire tests conducted have been carried out without mesh reinforcement, to demonstrate the ability of Cafco FENDOLITE®-MII5 to stay in place under the most severe fire conditions. However, for maximum long term in-service durability, the use of lightweight mesh reinforcement is recommended for exterior work and for interior use where vibration or mechanical damage and the possibility of subsequent loss of adhesion exist.
