| Aluminium Tripolyhosphate |
 |
Widely used in many kinds of primers, or mingle paint of primer and top-coat．It can be employed in phenol resin，alkyd resin，epoxy resin，acrylic resin and other oilsoluble resins or Water-soluble air drying or boking resin to produce paints with high anticorrosive performance，acid-resistance，Water-resistance and fire-resistance．
APW-2 modified Aluminium tripolyphosphate have approximately same properties，normal APW-2 is used in water-soluble paints． |
