| APTEK 2205-A/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 2205-A/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. Good wet strength holds components in place allowing for the movement of the circuit boards during processing; 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; Available at two levels of reactivity to meet various productivity needs; available in pre-weighted kits to minimize handling time; ideal for field repair operations APTEK 2205-A is a filled polyol resin that is safe to handle when used properly.. APTEK 2205-B is an organic isocyanate which make cause severe eye and skin irritation with direct contact.. Information provided by Aptek Laboratories, Inc. |
