Abstract

A synthetic resin foam is produced by mixing (a) a solution of a urea-, thiourea- or melamine-aldehyde resin with (b) a foamed liquid containing a hardener for the aminoplast, mixing being accomplished with the aid of compressed air of between 3 and 9 atmospheres gauge pressure and at least one of (a) and (b) being heated to 50-80 DEG C. before mixing. Pigments of different colours may be added to (a) and (b) so that the ratio of (a) to (b) may be checked from the colour of the product. In this case the concentration of the pigments in their respective components may be equal. Pigments specified are the water soluble dyes Acillan crocein and Acillan brilliant blue. The components may be stored separately in a pair of pressure containers one of which is fitted with a heater, the pair being insulated with foamed plastics material, e.g. the product of the invention, and having a common mixing outlet. Mixing is accomplished by supplying compressed air to the containers to force out the contents. The apparatus may be stationary or mobile and may contain a reserve pair of containers. Suitable apparatus are illustrated in Figs. 1-3 (not shown). The mixed components may be fed to a spray gun and used to make panels or to coat flat surfaces, tubes and shaped articles.
