Cramolin Isotemp

ISOTEMP is a transparent heat-, moisture- and water resistant protective silicone coating, indented for use in electronics especially for rigid and flexible PCboards. It retains its effectiveness up to 500° C. In addition it is flame retardant (in accordance with UL 94), elastic and well-bonding. ISOTEMP is also suitable for sealing components from humidity, salt, fungus and corrosive vapors.

ISOTEMP is particularly suitable for the insulation of printed circuit boards that are expected to withstand high temperatures during operation as for example in motor vehicles, aeronautical and aero spatial engineering, etc. It is also suited for the sealing of cabinets, data communication, instrumentation, marine, energy and heavy industry.

Shake can well before use. Surface to be treated has to be free of greases, oil, wax etc. Spray on the whole surface of parts to be treated, maintaining a distance of approximately 30 cm, otherwise the layer applied will flow. The laquer will be dry to permit handling after one or two hours, and fully curred after approx. 24 hours. To obtain to complete electrical and mechanical values the laquers has to be curred about one hour at 200° C. The spray nozzle has a selfcleaning action. Should it nevertheless get clogged, clean it using solvent.

Shelf life is 2 years if stored correctly. Package after emptying to be disposed via metal scrap.
