INSULCAST 275
THIXOTROPIC EPOXY FOR DIP COATING OF COMPONENTS AND PC BOARDS

DESCRIPTION

INSULCAST 275 is a filled, thixotropic epoxy compound. It is used in dip coating of electronic components (resistors, capacitors) and circuit boards. Also, INSULCAST 275 can be used for bonding between metals, ceramics, plastics, wood, etc., and for filling coil spaces between transformer frames and windings.

HEALTH CAUTION:
Avoid breathing possible fumes, mists and vapors which can cause severe respiratory damage. Use of NIOSH approved breathing apparatus is required for more than minimal exposure. Always work in areas with adequate ventilation to allow dissipation of polyamine and other chemical fumes, and where applicable, solvent fumes. Use of goggles, protective garments, rubber gloves, protective cream is required. If material gets into eyes, flush thoroughly with clear water for twenty (20) minutes; then seek medical treatment. Avoid skin contact. Material can cause contact dermatitis. Always wash exposed areas immediately, using warm water and soap, followed by rinsing with clean water. Observe all safety precautions. It is important when using solvent based materials or solvents to keep away from open flame or ignition source.
