Thermadek Winter Grade

Product Description

THERMADEK WINTER GRADE is a two component, 1:1 ratio, rigid foam system which when processed through suitable spray machinery ( Graco / Gusmer / Glas-Craft ) will produce a rigid foam of approximate core foam density 40kg/m³ with exceptionally good adhesion to cold substrates.

Uses

THERMADEK WINTER GRADE is used for insulation in:

• Industrial / commercial walls or roofing
• Any particularly cold and conductive substrate, especially metal

THERMADEK WINTER GRADE can be used on substrates down to minus 5oC. When used externally the foam must be protected from ultra-violet radiation and atmospheric degradation by a suitable elastomer protective coating.

Equipment

THERMADEK WINTER GRADE can be processed through all standard foam spray machines. The machine should be capable of maintaining the mix ratio at ±2% accuracy and controlling the component temperatures at 40-50oC.

Recommended machine settings

Spray Techniques

The guidelines in Isothane Limited’s standard specification should be followed but the general requirements are as follows.

• The substrate should be clean, dry and free of dirt, grease, oil and loose particles.
• In certain cases primer may be necessary to maximise adhesion. (Consult ISOTHANE Technical department if necessary).
• The foam should be built up in passes of not more than 50mm at a time leaving 5 minutes for the foam to cool between passes.

Physical Properties

THERMADEK WINTER GRADE is a two component, polyurethane rigid foam that, when sprayed through suitable foam machinery, gives a product of nominal core density 40 kg/m³.
