Abstract (en)

[origin: CN105705585A] The invention provides additives to resin compositions for improved impact strength and flexibility. 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.
