Cho-Therm 1641 A/B Silicone Compound 12oz Kit (Includes 1086 Primer)
CHO-THERM 1641 compound is a one-component, thermally conductive, electrically insulating (non-acetic acid generating), silicone-based RTV adhesive/sealant/potting compound. The material offers high thermal conductivity, flexibility, excellent high and low-temperature resistance, as well as electrical insulation.

CHO-THERM 1641 allows components of circuits encapsulated in the cured compound to be accessed by cutting away the material, and after repair, the components can be re-encapsulated with no loss in performance.
CHO-THERM 1641 compound will adhere, but not permanently bond, to most non-silicone surfaces, though a permanent bond can be achieved using Chomerics’ CHO-BOND 1086 primer(included in this kit). If easy removal is needed, the package and heat sink should be brush painted with a mould release before application. Components potted in CHO-THERM 1641 compound have excellent thermal and mechanical shock resistance, thermal diffusivity and moisture resistance.
CHO-THERM 1641 compound can also be used as a cure-in-place thermal grease, with excess material curing to resist vapor degreasing while achieving very low thermal impedance. The cured CHO-THERM 1641 compound will not separate or migrate on the heat sink or circuit board.
