Product Data Sheet Contex Thermoguard 58620

Description:

Contex Thermoguard is a waterborne elastomeric, breathable smooth-textured top coat which can reflect near infra-red radiation and also provide thermal insulation in hot climates. The technology used in Contex Thermoguard can keep surfaces cooler and reduce heat build-up in indoor areas, conserve energy, and save the cost of electricity.

Contex Thermoguard is formulated on modified pure acrylic binder, which accounts for its excellent anti-carbonation property, crack-bridging ability, and excellent adherence to substrate, very high scrub resistance, outstanding UV resistance and weather stability.

Recommended use:

Ideal as finishing coat for various exterior building facades where electricity saving and thermal protection are required like commercial and residential buildings, power plants, etc.

Substrates:

Concrete, cement rendering, masonry, etc.

Features:

Unique thermal insulation properties Proven electrical saving abilities Excellent anti-carbonation properties Excellent anti-fungal properties

Safety:

Handle with care. Before and during use, observe all safety labels on packaging and paint containers, consult Hempel material safety data sheets and follow all local or national safety regulations. Avoid inhalation, avoid contact with skin and eyes and do not swallow. Take precautions against possible risks of fire or explosions as well as protection of the environment. Apply only in well-ventilated areas.

Surface preparation:

The surface should be stable, firm, dry, and free of dust, sand, loose old paint, laitance, dirt, grease and oil. It is recommended to apply a primer/sealer prior to the specified filling procedure. Touch-up with primer/sealer on areas repaired with filler is recommended prior to application of topcoats.

Application conditions:

Use only where application and drying can proceed at temperatures above 5 C, and relative humidity is below 75%.

Remarks:

Drying data given is on the assumption that proper ventilation is provided.

Note:

*The physical constants stated are nominal data according to the Hempel Group’s approved formulas. They are subject to normal manufacturing tolerances and where stated, being standard deviation according to ISO 3534–1. **The theoretical spreading rate has been calculated for the stated volume solids and dry film thickness. A practical spreading rate will depend on the actual dry film thickness, the nature of the substrate and the relevant consumption factor.

The physical constants are subject to normal manufacturing tolerances.
