1.Application: Primer is a kind of EMI surface material .Which is
need to plate, the primer is spray to metalize the plastic. After
coating the copper or nickel, then the material can act the EMI
(1) Fast drying, low temperature baking so can enter the next
(2)Good adhesion for the plastics(such as ABS,PC+ABS,PC,PVC)and
other non-metallic material.
(3)One process can replace the traditional coarsening process and
sensitization process and activation process. So the cost is lower and the efficiency is
(4)Reduce the pollution.
(5)Use the spraying process. It is easier than other operation
(6)Spraying process is easy the other operation.
(7) Film is fine and do not spoil the liquid of chemical plating.
3. Technical indexes
(1) Ratio:Prime: Thinner =1:3 (wt.)
(5)Dry condition (50～60℃)30min
(6)Viscosity:10～15 s / 15℃
10～12 s / 25℃
8～11 s / 25℃
4. Operation Instruction
(1)The times of spraying: suggest one times .
(2)Treatment of surface and substrate: surface must clean, so it is
(3)Temperature: the temperature of substrate need exceed more than
3 ℃ higher than the dew point.
(4)The Spray method:
Nozzle diameter: 1～3mm
Air pressure: 0.3～0.4MPa(3～4kg/m2)
(5) Cleaning agent:special diluents.
5, Notes for Storage and Using
(1)Guarantee date: twelve months since the date of production.
(2) Before using the primer ,it should be mix completely, then use
the 120 mesh silk to filter.
(3) We have the power to change the data. So our customer must test
