Application of HumiSeal® 2A20  HV

Cleanliness of the substrate is of extreme importance for the successful application of HumiSeal 2A20 HV. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Adhesives can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue “no clean” materials.  Users should perform adequate testing to confirm compatibility between the adhesives and their particular assembly materials, process conditions and cleanliness level.

HumiSeal® 2A20HV is a two-component (w/ heat option) cure, general-purpose urethane adhesive/encapsulant. Medium viscosity, thixotropic material with high shear-thinning properties, 1:1 mix ratio and long work life. Medium hardness with good flexibility. Wide range of applications with bonding capabilities to multiple substrates.
