International Interplus 634 is a single component, water based paint disbonder designed to remove coating residues from metallic substrates. Can be described as readily biodegradable as tested by OECD 301B CO2 Evolution test.
Interplus 634 is specifically designed to remove tightly adhering coating residues from metallic substrates prior to repainting with approved maintenance coatings. Coating residues include conventional epoxies, polyurethanes, alkyds, acrylics and water borne coatings.
Interplus 634 can be used where traditional surface preparation techniques, such as abrasive blasting, ultra high pressure hydroblasting or power tool methods are ruled out for operational, health & safety or environmental reasons.
Prior to application of Interplus 634, any loose rust or loose coating residue should be removed to aid penetration of the product. Surfaces not to be treated should be masked and protected with polyethylene. A strong ground sheet should be used to contain coating residue, product and rinse water.
It is strongly recommended that a small test patch should always be carried out on a representative area in order to ascertain the optimum application thickness and activation time required to successfully remove the coating residue. Activation times are very much dependent upon the in situ coating type and condition, however, a typical working time is within 6 to 16 hours. The resultant rinse washings collected during removal should be analysed by an independent laboratory to ensure disposal in accordance with local environmental legislation.
Optimal working temperature range is 5 - 35°C (41 - 95°F), however, it can be used at temperatures as low as 0°C (32°F) and a maximum of 60°C (140°F). For best results, it is advised to suitably cover the application area to reduce the effect of wind, rain and intense sunlight.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
