Peters Sharp Edge Protection (SEP) improves edge coverage
The Elpeguard Sharp Edge Protection concept from Lackwerke Peters addresses the problem of edge alignment when coating electronic components and improves edge coverage and thus insulation resistance.
With the Elpeguard concept Sharp Edge Protection (SEP), Peters is presenting an innovative approach at Productronica in the second half of November 2025. SEP takes into account the problem of edge alignment: according to the laws of physics, sensitive areas in the edge area are sometimes not sufficiently covered. When applying thin liquid coatings, the coating on edges and tips (e.g. soldering pins) is thinner than on flat surfaces due to the flow behavior. With Sharp Edge Protection, the electronics in these sensitive areas are now better protected against dirt or moisture.
Peters SEP increases the insulation resistance of electronics
As insulation resistance requirements become more stringent, coating thickness is playing an increasingly important role in industrial applications. With SEP, Peters offers a solution to ensure sufficient edge coverage for components and IC pins. This increases the service life of electronics in harsh environments, both in conventional applications in the range up to 100 volts and in high-voltage applications up to 1000 volts. The coating manufacturer from the Lower Rhine has three options in its repertoire for good edge coverage. Firstly, via special SEP modifications of the standard coatings in the acrylate and synthetic rubber sectors; secondly, via higher coating thicknesses through adapted application parameters; and finally, via gels, e.g. for soldering pins. Peters will be presenting the Elpeguard SEP concept to trade visitors at the world's leading trade fair in Munich from November 18 to 21, 2025 at stand A2.354.
