Product Description

Please note, this product is now discontinued. See Hempaline Defend 630 as a potential alternative.

Hempel Polyester GF 35920 is a high solid, two-component heavy duty lining system based on isophthalic polyester acrylic copolymer reinforced with glass flakes. Applicable in thick coats by standard heavy duty airless spray equipment.

Best Uses

Hempel Polyester GF 35920 is best used as a rust preventing coating for areas exposed to high abrasion and impact. Also as a rust preventing coating for areas requiring short intervals between application and seawater immersion - 6 hours at 20°C/68°F is required.


Film thickness / thinning, may be specified in another film thickness than indicated on the attached data sheet depending on purpose and area of use. This will alter spreading rate and may influence drying time and overcoating interval. Normal range dry is 650-750 micron/26-30 mils. Absolute minimum is: 500 micron/20 mils. Maximum not more than 1250 micron/50 mils.

Theoretically, the product contains 100% solid. Depending on the application and curing conditions some of the volatile reactants may evaporate. Furthermore, the curing process is accompanied by a contraction. These two factors result in a “theoretical” volume solids of 85% and a spreading rate of 1.3 m²/l at 650 micron (53 sq.ft./US gallon).

By unfavourable application conditions, higher losses may result in a practical spreading rate of approximately 1.2 m²/l at 650 micron (49 sq.ft./US gallon). The curing is, however, not affected by a higher loss.

Overcoating: Overcoating intervals related to later conditions of exposure: If the maximum overcoating interval is exceeded, roughening of the surface is necessary to ensure intercoat adhesion. Before overcoating after exposure in contaminated environment, clean the surface thoroughly with high pressure fresh water hosing and allow drying.
