Abstract
Experience has shown that unprotected steel constructions have low resistance during fire, as the steel very quickly loses its bearing capacity. To counteract this, the individual parts of the steel construction can be thermally insulated, but this involves, of course, an increase in the outer dimensions of the construction. The use of intumescent coatings for fire protection of structural steel, as long as the paint is effective, can be an excellent solution to the problem. A characteristic of this type of paint is that, with increasing temperature, a number of chemical processes take place and the layers of paint become many times thicker. A heat insulating effect is thus achieved. The aim of this study is to attempt to provide answers to the following two questions: 1) Can an intumescent coating swell up quickly enough in a fire spreading as rapidly as one caused by plastics? and 2) Is intumescent coating effective in the atmosphere of combustion products from burning plastics? A further aim of the study is to provide, from numerous measurements, data which can be used in connection with both intumescent coating and plastic combustion.
