FIELD: chemistry.
SUBSTANCE: elastic quick-setting polyurethane adhesives with high adhesion to nonferrous metals, wires, including PVC sheathing, glass textolite, polycore, lavsan-type film materials, polyamide, with shearing strength of 5.0…7.0 MPa. The composition is especially recommended for attaching sensors, different elements when assembling radioelectronic equipment and electro-radio articles.
EFFECT: low viscosity of the adhesive which ensures quality connection of miniature elements; and minimum gas release from the hardened adhesive under vacuum-thermal effects according to GOST R 50109-92; a valuable property of the disclosed adhesive is its repairability, ie the possibility of breaking the adhesive joint in case of defective articles.
