Aptek 2120 PMF Low modulus urethane staking compound

Premixed-frozen, low modulus urethane staking compoundAPTEK 2120-PMF is a one component, premixed-frozen, thixotropic, electrically insulating soft urethane adhesive. It was designed for the staking of electrical/electronic components to printed circuit boards. APTEK 212-PMF is a 100% solids, solvent free system that will not form voids during cure or outgas after being fully cured. APTEK 2120-PMF is a non-TDI based urethane system which has outstanding reversion resistance and physical stability when subjected to high heat and humidity environments. As a urethane, this system displays higher ionic purity than epoxy systems minimizing the chance of corrosion around sensitive components and circuitry. Premixed-frozen and packaged in syringes for convenient dispensing to circuit board; Low modulus to minimize stress to sensitive components and ceramic substrates; Low Tg for excellent low temperature cycling and performance; Excellent substrate adhesion; superior to silicones.
