Product Description

ARMOUR - LYTE R is a polyether based resin system which, when combined with Armour - Lyte H will produce a resilient, durable polyurea elastomer specifically designed for easy application with good physical properties. This material has been formulated to perform in a wet environment and exhibits good resistance to hydrolysis.

ARMOUR-LYTE is available in a range of colours as indicated.

White	Black	Red
Yellow	Green	Blue
Orange	Grey	Brown

Typical Applications

• Corrosion Protection
• Hail, bird and traffic protection over polyurethane foam
• Heavy duty tank lining
• Coating Polystyrene to form convincing but lightweight architectural features

Processing

ARMOUR - LYTE is processed through specially designed dispensing equipment having accurate metering pumps for the two components. The components should be maintained at 40- 60ºC and mixed and sprayed by the appropriate equipment, on which Isothane technical staff can advise.

Cured elastomer to be repaired should be abraded and traces of dust removed. Maximum adhesion will be obtained if the surfaces to be repaired are heated to a minimum of 35ºC. Some surfaces will require the use of an Isothane primer.

Ambient conditions should be suitable for PU processing, with particular emphasis on humidity is 90% or above or the substrate temperature is less than 3ºC above the local dew point.

Storage, Handling and Personal Protection

• ARMOUR-LYTE should be stored in dry conditions at a temperature 20-25º C.
• Armour-Lyte R resin has a shelf life of 6 months. Armour-Lyte H has a shelf life of 6 months if stored at 20-25º C.
• Opened, part used containers must be resealed immediately after use.

The recommendations in our Safety Data Sheet for this product must be followed at all times. More general information is included in our publication “A Guide to the Safe Handling of Polyurethane Chemicals” and in the following Technical Data Sheet which is available on request:-

• Decontamination of Isocyanates using Isothane Decontaminant.

Additional Information

ARMOUR - LYTE R resin may require some agitation before use, in order to effect redispersion of any pigment. Recirculation of both components from the barrel, through the machine’s heater blocks and back to the barrel, is recommended when using standard 2:1 or 1:1 transfer pumps, in order to prime the materials and machine. 30 minutes of recirculation to warm the components to around 40º C will be adequate.

Post Curing: Articles need not be post cured.
