INSULBOND 839
ADJUSTABLE FLEXIBILITY EPOXY ADHESIVE

DESCRIPTION

INSULBOND 839 is a thixotropic paste epoxy adhesive with adjustable flexibility. INSULBOND 839 can be cured at room temperature or at elevated temperatures. The INSULBOND 839 flexibility is determined by the amount of Part B used. INSULBOND 839 exhibits a good mechanical bond, peel strength and thermal shock resistance with adhesion to glass, ceramics, most metals and plastics.

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.
