POLYISOCYANURATE BASED ADHESIVE Russian patent published in 2012 - IPC C09J175/04 C08G18/10 C08G18/16 C08G18/72 B32B7/12 

Abstract RU 2451709 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a polyisocyanurate based adhesive which is obtained by reacting an organic polyisocyanate with a compound containing hydrogen atoms which are reactive towards isocyanate, in the presence of a trimerisation catalyst. The organic polyisocyanate is a polymer or prepolymer polyisocyanate, and content of the soft block in the adhesive ranges from 40 to 60 wt %. A reaction mixture for producing said adhesive is also described.

EFFECT: obtaining an adhesive capable of withstanding high maximum stress, having extremely fast setting and having a good and strong bond with the base, as well as high thermal stability, resistance to salty water and creep.
