An epoxy or hardener mixture comprising (a) optionally water, (b) at least one hardener or epoxy resin, and (c) from 0.1 to 20 weight percent, based on epoxy resin of at least one distyryl phenol, tristyryl phenol or cumylphenol based additive surfactant with phosphate or sulfonate end groups having the structure R&#x2014;OXn-W wherein R designates a polystyrylphenol or cumylphenol, preferentially chosen from among distyrylphenol, tristyrylphenol or cumylphenol, and mixtures thereof, and wherein OX designates ethylene oxide and/or propylene oxide. The number of groups 'n' varies from 0 to 200, and W designates H, sulfate (&#x2014;SO) or phosphate (&#x2014;POH or &#x2014;PO&#x2014;OXnR). Freeze thaw resistance and improved stability is obtained in epoxy mixtures used in dispersion form. Improved pot life and cure time is obtained using either the epoxy mixture, the hardener mixture or a combination of the two in epoxy hardener formulations.

Water borne epoxy resin dispersions and epoxy hardener compositions

The invention provides a composition comprising: (a) about 0% to 99% by weight of at least one resin wherein the resin is selected from the group consisting of epoxy, latex, polyurethane, polyurea, polyspartic, or alkyd resins; (b) about 1%-99% by weight of tristyrenated phenol or distyrenated phenol; and (c) optionally about 2% to 98% by weight of an additional solvent.

Additives to resin compositions for improved impact strength and flexibility

A two-package moisture curable composition is provided. The composition comprises a first part comprising at least one silane terminated polyurethane and a second part comprising at least one silanol terminated polysiloxane; wherein the silane terminated polyurethane based polymer has at least one end group of the general formula: &#x2014;A&#x2014;(CH)m-SiR(OR), where A is a urethane or urea linkage group, Ris selected from Calkyl, alkenyl, alkoxy, aminoalkyl, aryl and (meth)acryloxyalkyl groups, Ris each substituted or unsubstituted Calkyl or C-Caryl groups, m is an integer from 1 to 60 and n is an integer from 0 to 1; wherein the silane terminated polyurethane is prepared using natural oil polyols and their derivatives; and wherein the composition, after moisture cured, forms a surface whose water contact angle is larger than 101&#xb0;. The composition is suitable for applications in antifouling coatings which afford low surface energy and improved mechanical performance.
