- Abstract
- What fire hazards to actually various types of paints and varnishes give during the spraying phase itself and has the application equipment any influence? this is the problem which has formed a basis for the investigation shown in this report. A number of typical types of varnishes has been chosen and tested at the Swedish National Testing Institute (SP) with respect to the fire characteristics of the spray. Both the tendency to ignite and the consequences of a continuous fire have been examined; the latter by determining the combustion efficiency and the amount of energy developed. The conclusion that could be drawn from the tests is that high pressure spraying in general leads to considerably higher fire hazards than conventional spray painting. The spray is easier to ignite and it burns with a high combustion efficiency as well. Liquid paintings are diveded into different clases depending on their flash point. Any major difference between varnishes in flash point class I (flash point <21 deg C) and IIB (flash point 31-55 deg C), respectively, could not be noted. Among the tested varnishes could even the class IIB varnish be judged as the most hazardous from a combustion point of view.
