Abstract
The embodiments described herein generally relate to methods and chemical compositions for coating substrates with a composition. In one embodiment, an adhesive composition is provided comprising a reaction product of a polyacid selected from the group consisting of an aromatic polyacid, an aliphatic polyacid, an aliphatic polyacid with an aromatic group, and combinations thereof, or a diglycidyl ether; and a polyamine; and one or more compounds selected from the group consisting of a branched aliphatic acid, a cyclic aliphatic acid with a cyclic aliphatic group, a linear aliphatic, and combinations thereof.
Claims18
An adhesive composition, comprising:
- a reaction product comprising:
- an adduct or product comprising from about 25 wt. % to about 96 wt. % of the adhesive composition, the adduct or product comprising:
- a diacid comprising from about 40 wt. % to about 90 wt. % of the adduct or product, and the diacid is selected from the group consisting of an aromatic diacid, an aliphatic diacid with an aromatic group, and combinations thereof, wherein an aromatic ring of the aromatic diacid and the aromatic group of the aliphatic diacid are, independently, substituted with a functional group selected from the group consisting of amine, hydroxyl (—OH), C1-C12 alkyl, alkylamino, alkyloxy, alkenyloxy, alkylcarboxy, alkylnitro, and alkylsulfonyl;
- and
- a polyamine comprising from about 10 wt. % to about 60 wt % of the adduct or product, and the polyamine is selected from the group consisting of triamines, tetramines, and combinations thereof;
- and
- one or more compounds comprising from about 4 wt. % to about 75 wt. % of the adhesive composition, the one or more compounds selected from the group consisting of a branched aliphatic acid having C2-C26 alkyl group, a cyclic aliphatic acid with C7-C30 cyclic aliphatic group, a linear aliphatic acid having C2-C26 alkyl group, and combinations thereof, the reaction product comprising
- R1-dAmdAc-dAmnR2,
- wherein:
- n is 1 to 10,
- R1 and R2 are each independently selected from the group consisting of a branched aliphatic acid having C2-C26 alkyl group, cyclic aliphatic acid with C7-C30 cyclic aliphatic group, a linear aliphatic acid having C2-C26 alkyl group, and combinations thereof,
- dAm comprises a polyamine, and
- dAc comprises a diacid;
- and
- wherein a total wt. % of the adhesive composition is 100 wt. %.
An adhesive composition, comprising:
- a reaction product comprising:
- an adduct or product comprising from about 25 wt. % to about 96 wt. % of the adhesive composition, the adduct or product comprising:
- a diacid comprising from about 40 wt. % to about 90 wt. % of the adduct or product, and the diacid is selected from the group consisting of an aromatic diacid, an aliphatic diacid with an aromatic group, and combinations thereof;
- and
- a polyamine comprising from about 10 wt. % to about 60 wt. % of the adduct or product, and the polyamine is selected from the group consisting of triamines, tetramines, and combinations thereof;
- and
- one or more compounds comprising from about 4 wt. % to about 75 wt. % of the adhesive composition, the one or more compounds are selected from the group consisting of a branched aliphatic acid having C2-C26 alkyl group, a cyclic aliphatic acid with C7-C30 cyclic aliphatic group, a linear aliphatic acid having C2-C26 alkyl group, and combinations thereof,
- wherein the reaction product comprises
- R1-dAmdAc-dAmnR2,
- wherein:
- n is 1 to 10,
- R1 is a branched aliphatic acid having C2-C26 alkyl group,
- R2 is a branched aliphatic acid having C2-C26 alkyl group, a cyclic aliphatic acid with C7-C30 cyclic aliphatic group, or a linear aliphatic acid having C2-C26 alkyl group,
- dAm comprises a polyamine, and
- dAc comprises a diacid;
- and
- wherein a total wt. % of the adhesive composition is 100 wt. %.
