Abstract

A rain-fast bioactive composition includes a bioactive substance and an aqueous suspension concentrate of a latex polymer emulsified with an in-situ crosslinked hydrocarbon polymer.

Claims (10)

1 . A rain-fast bioactive composition comprising:

(a) a bioactive ingredient, and

(b) a suspension concentrate of a latex polymer emulsified with an in-situ crosslinked hydrocarbon polymer.

2 . A rain-fast bioactive composition according to claim 1 wherein (b) comprises 12-14% by weight of said polymer in water.

3 . A rain-fast bioactive composition according to claim 1 wherein the weight ratio of (a):(b) is about 1:0.5 to 1:0.01.

4 . A rain-fast bioactive composition according to claim 3 wherein said ratio is about 1:0.1 to 1:0.05.

5 . A method of increasing the rain-fastness of a bioactive composition which is applied to a substrate comprising including therein a water thickener which is a suspension concentrate of a latex polymer emulsified with an in-situ cross-linked hydrocarbon polymer.

6 . A method of sustained release of a biocide from a bioactive composition which is applied to a substrate comprising including therein a water thickener which is a suspension concentrate of a latex polymer emulsified with an in-situ cross-linked hydrocarbon polymer.

7 . A method according to claim 1 wherein said substrate is gypsum board or sheet rock.

8 . A use formulation including the rain-fast composition of claim 1.
