Zinc chromate vinyl primer
ADVANTAGES
* Excellent adhesion over smooth, ferrous and non-ferrous metal.
* Can be coated with almost any types of coatings.
* Outperforms 1-GP-121 specification.
* Meets BNQ 3714-121 specification.
USES
Etching primer for steel, copper, zinc and some (stainless steel, galvanized steel
and aluminum).
STORAGE
This product may be stored for a minimum of 12 months in its original unopened
container at a maximum temperature of 35°C (95°F).
RESTRICTIONS
Do not use on substrate that will be immersed in water for a long period of time.
Loss of adhesion and blistering can occur.
Due to the difference in alloy composition and, in order to ensure proper
adhesion, each metal alloy must be tested individually and approved prior
to its use.
Adhesion to substrate: 100% - 5B (ASTM D-4212)
Corrosion resistance:
See other anticorrosive primers and finishing enamels.
Humidity resistance:
See other anticorrosive primers and finishing enamels.
