International Interplus 880 is a low VOC, two component high solids flexible aliphatic surface tolerant polyurethane primer, intermediate or finish capable of producing high build films.
International Interplus 880 is primarily used as a high performance single coat industrial maintenance coating to upgrade any tightly adhering existing coating to a longer life durable system.
For use in a wide variety of aggressive environments, including those found in chemical plants, refineries, pulp and paper mills and on bridges. it is capable of providing superior gloss and colour retention particularly when compared to epoxy based finishes and will cure at temperatures down to -5°C (23°F). It may be applied to steel surfaces where it is not possible to abrasive blast.
The performance of this product will depend upon the degree of surface preparation. The surface to be coated must be clean 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.
Abrasive Blast Cleaning
Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Interplus 880, the surface should be reblasted to the specified visual standard.
Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.
Power Tool Preparation
Power tool clean to a minimum St3 (ISO 8501-1:2007) or SSPC-SP3. 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.
Interplus 880 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.
See Product Characteristics section for further details
Interplus 880 is suitable for overcoating all sound aged coatings but is not generally recommended for direct application to zinc silicate (e.g. Interzinc 22) or zinc epoxy (e.g. Interzinc 52).
