Storage

Store in well ventilated and dry conditions when temperature is -10℃~40℃and RH is less than 90%. Keep away from hot and fire.Shelf Life:12 months 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

Using pneumatic grinding tools with P80~P120 sandpaper to brush blade surface or dried putty. Ensure that the surface is clean before paint coating without dust, grease, water droplets and other pollutants.

Curing condition

The suitable temperature for applying 725-S06-15 is 5～40℃.

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 ventilate 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=2.38:1~2.48:1 or volume ratio A:B=2.05:1~2.15:1.

Add group B into group A and mix evenly before coating application.
