|---|---|
| Intertek: | Intumastic 270 has been successfully tested at Intertek laboratories to the following international test standards: IEC 60331-1 - Circuit Integrity IEC 60332-3-22 - Flame Propagation IEC 60754-1 - Halogen Gas Content DEFSTAN 02-711-2 - Smoke Index |
| FM Global: | Thermo-Lag 270 has been tested and approved by Factory Mutual Research Corporation at 1/16" (1.6 mm) dry thickness and evaluated by Sandia Laboratories in tests sponsored by the U.S. Nuclear Regulatory Commission using both propane and diesel fuelled fires Ampacity tests run by Factory Mutual show “No electrical derating necessary when a cable is coated (and cured properly) with Thermo-Lag 270.” The temperature attained was well below the maximum temperature rating of the cable insulation. Heat transfer calculations should be used to calculate derating requirements of large groups of conductors Factory Mutual Research Corp. Sandia Labs

General
| Product Information | |
|---|---|
| General: | Thermo-Lag 270 may be applied by spray, trowel, or hand application. When spray applying, Thermo-Lag 270 must be thinned 5% by volume (1 quart water per 5 gallons maximum). A single coat built up with a number of quick passes allows greater control over quantities, thickness and finish. In most conditions, it is advantageous to apply two thin coats rather than one thick coat |
| Application Rates: | At an ambient temperature of 21°C, apply 1/8" (3mm) per coat (wet) |
| Wet Film Thickness: | Frequent thickness measurements with a wet film gauge are recommended during the application process to ensure uniform thickness |
| Palming: | Hand application of Thermo-Lag 270 may be more economical when cables are "ganged" or for protecting individual strands. Rubber gloves are recommended |
| Trowel: | A standard plasterer's hawk and trowel may be used for suitable applications Selection of instruments is left to the discretion of the applicator |
| Mixer: | Use 1/2" electric or air driven drill with a slotted paddle mixer (300 rpm under load) |
| Mixing: | Thermo-Lag 270 must be mixed using a 1/2" electric or air driven drill with a slotted paddle or Jiffy mixer blade. Mix material for a minimum of 5 minutes to achieve the necessary texture required before spraying |
| Thinning: | Thermo-Lag 270 may be thinned with clean potable water up to 5% by volume |
| Airless Spray: | Use 45:1 airless (minimum) with Dura Flow lower cylinder (3/4" outlet) / 3.3 gal. per minute to provide an operating pressure of 3,000 p.s.i. (210 kg/cm² *Remove filters and surge tanks. Set bottom ball to greatest travel. Hopper feed optional. Teflon packings are recommended |
