FIELD: chemistry.
SUBSTANCE: invention relates to a composition which is suitable for use as a joint sealing compound. The composition contains water, filler, binder and a biocide. The filler is selected from one or more materials which are selected from calcium carbonate, calcium sulphate dihydrate or calcium sulphate polyhydrate. The binder is selected from a group consisting of vinyl-, acryl- and styrene-containing compounds, polymers or copolymers of vinyl-, acryl- and styrene-containing compounds, starches, casein and mixtures thereof. The biocide contains isothiazolinone. A conditioned sample of the composition becomes formaldehyde-free after 24 hours.
EFFECT: composition has improved properties and operational characteristics.
