Storage
Store in well ventilated and dry conditions when temperature is 0℃~35℃ and RH is less than 90%.Keep away from hot and fire. Shelf Life: 12months minimum at 25℃Subject to re-inspection thereafter.
Systems and Compatibility
Consult your Representative for the systems best suited for the surfaces to be protected.
Surface Preparation
725-WS52-16 should be applied over 725-S06-15. The primer surface should be clean, dry and free from contamination.725-WS52-16 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 and 725-S06-15 should be used before the application of 725-WS52-16.725-WS52-16 may be applied directly over aged 725-WS52-16 following thorough fresh water washing and degreasing provided the coating to be overcoated is in an intact and tightly adherent condition. Loose or flaking coatings should be removed back to a firm edge and 725-S06-15 should be used to repair the area before application of the full coat.
Curing condition
The suitable temperature for applying 725-WS52-16 is 10～35℃.
Apply in good weather. Temperature of the surface to be coated must be least 3℃ above the dew point when the humidity is lower than 85%.
It must be ventilated above 8h at pool ventilation area.
The paint group A and B shall be mixed evenly and no coarse particles shall be visually detected. Filter with 60-mesh filter when coarse particles are visually detected.
Mix according to the ratio of mass ratio A:B=5.7:1~5.9:1 or volume ratio A:B=4.2:1~4.4:1. Add group B into group A and mix evenly before coating application.
