Roughness blasting can be precisely matched to material and requirements and achieves an optimum basis for further surface processing. Precisely defined roughness values ensure that the subsequent coating or painting virtually "claw" into the surface. The most important factor is the number of profile peaks, the RPc value. These peaks can be increased, enlarged and interlocked by selective processing with angular blasting grain.
Rough blasting requires the know-how and experience of a specialist like KST. This specialist first determines the best roughness value for the project by carefully selecting the abrasive and grain shape, blasting pressure and speed, system technology and other setting parameters. The process is also very well suited for the partial treatment of mechanically finished components.
