International Interplus 4101 Clean Gel

International Interplus 4101 Clean Gel is a single component water-based rust remover / cleaner gel, which conforms to the yellow classification of the Harmonised Offshore Chemical Notification Format (HOCNF).

Best Uses

Interplus 4101 Clean Gel is effective for the removal of corrosion on stainless steel structures and aluminium. It has been designed to remove light to medium rust spots on a variety of surfaces, and is also suitable for use as a cleaning agent to remove rust stains in coated areas.

In addition, Interplus 4101 can be used as an alternative to traditional sandblasting, ultra-high pressure water blasting or power tool methods where these have been ruled out for operational, health and safety or environmental reasons.

Application

The recommended application method for this product is Airless Spray. Brush and Roller are suitable for small areas only.

Any loose rust deposits should be removed prior to application of Interplus 4101 Clean Gel, this will aid with penetration of the product. Ensure that all surfaces that are NOT being treated are masked off and protected with polyethylene. Galvanised surfaces can be affected by Interplus 4101 and should therefore be covered. A strong ground sheet should also be used to contain residue, product and rinse water.

Please note that use of Interplus 4101 Clean Gel on GRP will cause discolouration of the surface.

Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

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 rust deposits.

Activation times are very much dependent upon the in situ rust level and condition, however, a typical working time is within 12 to 24 hours.

Pure epoxy topcoats can experience white staining when using Interplus 4101 Clean Gel; please test a large enough area before use if this may be an issue.

Application Conditions

Optimal working temperature range is 8 - 37°C (46 - 99°F). Interplus 4101 Clean Gel can be used at temperatures as low as 2°C (36°F) and a maximum of 60°C (140°F), but a lower level of performance should be expected.

For best results, it is advised to suitably cover the application area to reduce the effect of wind, rain and intense sunlight.
