4.1.1 WHAT KIND OF SPRAYING MATERIAL CAN BE APPLIED

➞ Paints containing solvents of the explosion class II A.

➞ Enamels, primers, textured paints etc., which have a speciﬁ c resistance of > 50 kΩ

(according to the WAGNER or Ransburg scale).

➞ The effectiveness of the spraying action is always dependant on the composition of

the paint being used, e.g. pigments or resin.

Note

With very highly conductive materials or those with a very high electrical resistance, the

electrostatic effect does not work as efﬁ ciently. The relationship between the values of the

high-voltage (kV) and the current (µA), shown on the HVM 2082, denotes the charging

capacity of a spray material.

➞ High kV value, low µA value (no wrap around) = Paint with too high el. resistance.

➞ Low kV value, high µA value (no wrap-around) = Paint with too low el. resistance

In the event of application problems, contact your WAGNER branch and the paint manu-

facturer.
