The primer surface should be clean, dry and free from contamination.725-H42-30 must be applied within the coating interval specified (consult the relevant product data sheet). Areas of breakdown, damage etc. should be prepared to the specified standard (eg. St3) and primed prior to the application of 725-H42-30.

Repair/On Board Maintenance

725-H42-30 should be applied over a recommended primer coating scheme. The primer surface should be clean, dry and free from contamination.725-H42-30 must be applied within the coating interval specified (consult the relevant product data sheet).

Limitations

In common with all epoxy base coatings, 725-H42-30 will exhibit chalking of the firm on UV exposure.

Apply in good weather. Temperature of the surface to be coated must be least 3°C above the dew point when the humidity is lower than 85%.

The dry time and overcoating interval may change according to the environment factors.

Avoiding absorb the solvent steam and paint steam for long time. Skin and eyes must avoid contacting the paint. Pay attention to ventilate and fireproof when applying.
