FIELD: chemistry.
SUBSTANCE: water dispersion contains polyurethane dispersion and water dispersion of silicon dioxide. Polyurethane dispersion has the average size particle of polyurethane polymer in the range from 60 to 350 nm. The water dispersion of silicon dioxide has SiO2 particles diametre from 20 to 400 nm. Polymer dispersions are used as glues for gluing of any substrates same or different type.
EFFECT: high initial thermal durability of glue joints.
