Precautions

l           The products are not suitable for exposure to acidic or alkaline   environment

l           In the course of the spraying, dry film thickness of foremost zinc   silicate primer is suggested to be 50 micron in order to ensure maximum   surface strength, and prevent surface painting shelling off; zinc silicate   primer should guard against airslake, or to pay attention to maintaining   painting surface cleaning, no zincifications.

l           Coating thickness of this product will affect the shortest re-coating   interval and handling time, and may lead to the re-coating of the adversely   affected; environmental factors should be properly considered during   construction.

l           The products is solidified completely in more than 150℃(302)degrees, needs of   solidification five days or more, otherwise the painting will be facing some   thermoplasticity. The coating is not being heated before thoroughly dried.
