Interline 399

Description

A high performance, highly crosslinked two component epoxy novolac tank lining, with excellent heat and solvent resistance.

Where To Use

Suitable for internal lining of storage vessels, process vessels and pipe internals at elevated
temperatures up to 130°C (266°F).

Technical Information

The detailed Interline 399 Application Guidelines should be consulted prior to use.
Interline 399 is typically specified as a three coat system at 90 microns (3.6 mils) per coat to give a total coating system dry film thickness of 270 microns (10.8 mils). Exact specification for total dry film thickness will be dependent upon service end-use requirements. Consult International Protective Coatings for specific advice regarding tank lining applications. Maximum film build in one coat is best attained by airless spray. When applying by methods other than airless spray, the required film build is unlikely to be achieved. Application by air spray may require a multiple cross spray pattern to attain optimum film build. The use of other methods, e.g. brush or roller, may require more than one coat and are suggested only for small areas and initial stripe coating. 

Surface temperature must always be a minimum of 3°C (5°F) above dew point. Do not apply at steel temperatures below 10°C (50°F).The relative humidity during application and curing should not exceed 80%. When applying Interline 399 in confined spaces ensure adequate ventilation. Good ventilation throughout application and cure, and firm control of film thickness, are essential to ensure full removal of retained solvent and optimum performance of cured film. Total coating system film thickness must not exceed 350 microns (14 mils).

The curing times will vary depending upon dry film thickness and conditions that exist during application and throughout curing periods.
