ADHESIVE FOR FINAL FINISHING OF SEAM Russian patent published in 2019 - IPC C09J129/04 C04B26/04 C09J131/04 

FIELD: construction.

SUBSTANCE: invention relates to adhesive composition for reinforcement of panel joints in construction. Technical result is achieved by an adhesive composition containing a polymer binder, filler and an associative thickener. Binder is a combination of polyvinyl acetate and polyvinyl alcohol in amount of 10–40 wt. % of the composition. Filler is a combination of attapulgite clay in amount of 0.5–1.5 wt. % of the composition and kaolin clay in amount of 5–15 wt. % of the composition. Rheology modifier consists of at least one cellulose-based rheology modifier in amount of 0.01 to 15 wt. % of the composition. Associative thickener consists of at least one associative thickener based on polyacrylate and is used in amount of 0.01 to 5 % by weight of composition. Viscosity of the composition ranges from 100 to 200 Brabender units and density ranges from 7.5 (0.88987 kg/l) to 10 pounds/gallon (1.198 kg/l).

EFFECT: technical result is to eliminate the need for a multilayer coating of the seam sealant and to reduce the time required to mount the wall.
