Cramolin Urethane Clear

URETHANE CLEAR is a high-quality single component polyurethane lacquer, that protects and insulates PC boards, electrical motors, transformers, electronic equipment and components. It offers protection from different environmental conditions such as humidity, salty corrosive vapors, fungus and thermal and mechanical stress. It forms a hard, stable, flexible, non-conductive and wear resistant film with excellent adherence.

Protection of printed circuit boards, components, wires, cables, etc. URETHANE CLEAR eliminates or prevents cree page current, corona effects, short circuits or discharges. It is also suitable for corrosion protection of parts subjected to bad atmospheric conditions.

First clean surface to be treated. DEGREASER is ideally suited to that task. Shake the can well before first use. Apply a uniform layer maintaining a distance of approx. 30 cm.
