Repair/On Board Maintenance

The areas to be repaired should be cleaned to St3(GB/T 8923-1988)by  mechanical method or higher level of surface prepared to Sa2.5(GB/T 8923-1988)by abrasive blasting. Abrade the area immediately surrounding the repair to provide a key for subsequent coating application. Overlap areas should be kept to a minimum.

Limitations

This product will not cure adequately below -10°C. For maximum performance ambient curing temperature should be above -5°C.

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%.

In common with all epoxy base coatings, 725-H53-201 will exhibit chalking of the firm on UV exposure.
