APTEK 2100-A7C/B is a thixotropic, two component, electrically insulating, low modulus urethane system designed for the staking of electrical/electronic components to printed circuit boards. Although APTEK 2100-A7C/B is capable of achieving full cure at room temperature, a short term exposure to moderate heat will greatly reduce processing time and optimize cured properties. 100% solids, solvent free system that will not form voids during cure or service life; Low Tg for excellent low-temperature cycling and performance; Very good substrate adhesion, superior to silicones; Exceeds NASA outgassing requirements for high vacuum environments APTEK 2100-A7C is a translucent, filled polyol resin. APTEK 2100-B is a yellow/orange, organic isocyanate. Information provided by Aptek Laboratories, Inc. |
