Product Description
HumiSeal 2A20 is a two-component polyurethane adhesive and encapsulant with matched typical viscosities of 9,000 cP for Part A and Part B. It is a soft, low-viscosity material for general-purpose bonding and encapsulation, with mechanical and thermal shock resistance and adhesion to metals, hard-to-bond plastics, glass, ceramics, polycarbonate, and electronic assemblies. Typical processing times are less than eight minutes of pot life and 10 minutes to handling. Full cure takes 18 hours under room-temperature conditions or 30 minutes at 65 deg C. Applications include electronics, automotive assembly, and industrial work.
