FIELD: polyacrylic resin-based joint sealing composition.
SUBSTANCE: composition comprises acrylate copolymers with C2-C5-alcohol group, acrylonitrile as a binder for fat compounds and plasticizer, as well as fillers and/or pigments, auxiliaries and water. Preferably epoxystearic methyl ester is used as fat compound and butylacrylate is used as acrylate comonomer. Composition has high elasticity and particularly useful for substrate with different thermal-expansion coefficient.
EFFECT: sealing composition with improved physical properties.
