Hempel Galvosil 15700

Hempel Galvosil 15700 is a two-component, solvent-borne, self-curing, inorganic zinc silicate with outstanding resistance against weathering and abrasion. It has excellent chemical resistance within the pH range 6-9. Offers cathodic protection of local mechanical damage.

Hempel's Zinc metal pigment 97170 is in full compliance with ISO 3549 and ASTM D520 type II.

Best Uses

Hempel Galvosil 15700 is best used as a general purpose, heavy-duty, rust-preventing primer. It can also be used as a single, complete coating for long-term protection of steel exposed to a moderately to severely corrosive environment and to abrasion. Also as a tank lining in accordance with the Hempel's Cargo Protection Guide.

Application

Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting with sharp abrasive to minimum Sa 2½ (ISO8501-1:2007) with a surface profile equivalent to Rugotest No. 3, BN10, Keane-Tator Comparator, min.3.0 G/S, or ISO Comparator rough Medium (G). In case of new steel to be exposed to no more than medium aggressive (industrial) environment and without any extraordinary demands to lifetime, a surface preparation degree of SSPC-SP6 may suffice.

The surface must be completely clean and dry at the time of application, and its temperature must be above the dew point to avoid condensation. At temperatures ranging from 0°C/32°F to 40°C/105°F, curing needs minimum 50% relative humidity. Curing is retarded at lower temperature and lower humidity. In confined spaces, provide adequate ventilation during application and drying.

Subsequent Coat

As a tank coating: None, i.e. no other paints are acceptable in combination with the product. Otherwise, according to specification.
