Product Description

International Interplus 770 is a low VOC, two component, high solids, internally flexibilised, surface tolerant epoxy primer/intermediate.

Best Uses

International Interplus 770 is used as a versatile, high performance maintenance coating to upgrade tightly adhering existing coatings to longer life durable systems.

It can be applied to steel surfaces where it is not possible to abrasive blast and is suitable for use in conjunction with ultra high pressure hydroblasting. In addition it is suitable for use in a wide range of industrial and coastal environments including pulp and paper plants, refineries, chemical plants, offshore structures, bridges and a range of industrial structures.

Interplus 770 is suitable for use over the following primers:

Application

The performance of this product will depend upon the degree of surface preparation. The surface to be coated must be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Accumulated dirt and soluble salts must be removed. Dry bristle brushing will normally be adequate for accumulated dirt. Soluble salts should be removed by fresh water washing. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning: Interplus 770 may be applied to a surface abrasive blast cleaned to a minimum Sa1 (ISO 8501-1:2007) C or D grade rusting, or SSPC SP7.

Hand or Power Tool Preparation: Hand or power tool clean to a minimum of St2 (ISO 8501-1:2007) or SSPC-SP2. Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun should be spot blasted to a minimum standard of Sa2 (ISO 8501-1:2007) or SSPC-SP6. Typically
this would apply to C or D grade rusting in this standard.

Ultra High Pressure Hydroblasting / Abrasive Wet Blasting: May be applied to surfaces prepared to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 which have flash rusted to no worse than Grade HB2½M (refer to International Hydroblasting Standards). It is also possible to apply to damp surfaces in some circumstances. Further information is available from International Protective Coatings.

Aged Coatings: Interplus 770 is suitable for overcoating aged coatings which show good adhesion. Loose or flaking coatings should be removed back to a firm edge. Existing epoxy or polyurethane systems which are glossy may require abrasion to ensure good intercoat adhesion.
