SPECIAL CONDITIONS FOR SAFE SPRAY GUN USE:
. . .
FAILURES AND REMOVAL OF THEIR CAUSES
When using the spray gun, heat hazards may be due to:
- the use of hot compressed air;
- heated primer and finish product application.
In these situations, at most, the spray gun surface reaches the compressed air or primer and finish product temperatures.
In these conditions, pay ATTENTION to the following:
- the spray gun surface temperature should not exceed the burning limit of 43°C (UNI EN 1953 paragraph 5.4).
If this is the case, hand protection must be worn: (for example, heat resistant antistatic gloves);
- the spray gun surface temperature should never exceed 85°C, temperature sufficiently lower than the minimum
ignition temperature (
TMA
) of solvents commonly used for bodywork, woodwork and industrial painting;
- in case of doubt, ask your dealer for information on the solvent
TMA
.
