METHOD OF PRODUCING LAMINATE CONTAINING A TWO-COMPONENT SOLVENT-FREE ADHESIVE COMPOSITION COMPRISING AN AMINE-INITIATED POLYOL Russian patent published in 2021 - IPC C09J5/04 C09J175/04 C08G18/10 B32B7/12 

FIELD: adhesive materials.

SUBSTANCE: invention relates to methods of producing a laminated structure containing two-component polyurethane adhesive compositions without a solvent. Method comprises uniform application of isocyanate component on first substrate, uniform application of polyol component on second substrate, joining the first and second substrates together and curing the glue for gluing the first and second substrates. Polyol component contains amine-initiated polyols containing primary hydroxyl groups and a basic chain containing a tertiary amine. Adhesive has viscosity of more than 10,000 mPa-s (at 40 °C) for 10 minutes after connecting the first and second substrates together.

EFFECT: faster curing and improved conversion efficiency.
