SHOP PRIMER--APPLICATION AND DEVELOPMENT

The problems of primer protection of shop blasted plates during assembling are presented. Shop-primer characteristcs are defined in terms of the technological and film-forming properties of the paint; the physical, mechanical, chemical, and protective properties of the film; and the physiological properties of its thermal decomposition products. Blasting operations are outlined and types and working mechanism of abrasives reviewed. Special attention is given to the structure of blasted surfaces and to its characterisation. The film-forming process is examined and the flow properties of shop primers in connection with the need for laying down homogeneous films of constant thickness discussed. On the basis of the thermal gradients found on the primed plates during cutting and welding, the main thermal decomposition products of the binder and pigments of shop primers are reported and their toxic properties and hazards briefly described. A review of the various types of shop primers in current use is given on the basis of their rust-inhibiting mechanism. The most recent trends in shop-primer development are outlined, with special emphasis on the formulation of highly protective types which give off fumes of the lowest possible toxicity during cutting and welding.
