After the process of screen preparation the next step is the selection of the appropriate stencil material. SPT offers with the FOTECO product range an extensive choice of such products. First we would like to introduce you to our traditional screen emulsions, based on pure DIAZO technology. The DIAZO powder is used to sensitize the emulsions and triggers the light sensitivity of the emulsion. It reacts with the various types of PVA (Poly Vinyl Alcohol). The result is a resistant stencil surface, which can be easily reclaimed after use.
