Application Information sheets (AI) apply to various lacquers/lacquer series’ and supplement the
Technical Reports on these lacquers by giving detailed explanations of possible application proce-
dures and individual process steps plus offering numerous practical tips and advice to safeguard
the optimum processing of our products.
The associated Technical Reports provide - in a concise and clear manner - numerous character-
istics and processing data in transparent diagrams, graphics and tables.

2.1 General characteristics
• high definition enables the representation of fine conductors
• UV and thermal curing
• excellent adhesion and high surface hardness
• the flake strippable etch and plating resists (index FS) offer the advantage that the flakes can be
2.2 Special characteristics of the liquid ELPEMER
• owing to their outstanding resolution, even ultra-fine conductors < 50 µm can be represented
• particularly suited for the production of multilayer inner layers.
