This product is an effective, nontoxic, lead-free and anticorrosive
pigment, widely used in anticorrosive coating materials. It
has the following characteristics:

|
|
3. Demand for the to-be-coated
surface is not very strict. Tight junctions between paint
and surface.
4. Get along well with base materials. Suitable for resins
such as alcohol acids, amino acid epoxy chlorinated rubber.
5. Small refracting power; can be used as finish paint as
well as primer; easy color mixing.
6. Good anticorrosive performance. In this respect, can be
compared with zinc chromate. |
