First claim
Opening claim text (preview).
What is claimed: 1. An amine endcapped adduct composition comprising: an amine endcapped adduct formed from a monofunctional epoxide and a polyether primary triamine having a polyethylene glycol backbone, wherein the monofunctional epoxide and the polyether amine are combined in a molar ratio of 1.0:2.0 to 1.0:8.0 moles of epoxide functionalities to moles of polyether amine functionalities. 2. The amine endcapped adduct composition of claim 1 , wherein the monofunctional epoxide has an epoxide equivalent weight of 100 grams to 8000 grams. 3. The amine endcapped adduct composition of claim 1 , wherein the polyether amine has an amine equivalent weight of 30 grams to 2000 grams. 4. The amine endcapped adduct composition of claim 1 , wherein the monofunctional epoxide is selected from the group consisting of monofunctional aliphatic glycidyl ethers, monofunctional aromatic glycidyl ethers, or a combination thereof. 5. An epoxy endcapped adduct composition comprising: an epoxy endcapped adduct formed from the amine endcapped adduct composition of claim 1 and a multi-functional epoxide, wherein the amine endcapped adduct composition and the multi-functional epoxide are combined in a molar ratio of 1.0:2.0 to 1.0:8.0 moles of amine endcapped adduct functionalities to moles multi-functional epoxide functionalities, wherein the epoxy endcapped adduct composition has a viscosity at 25° C. of 5000 centipoise to 50000 centipoise. 6. The epoxy endcapped adduct composition of claim 1 , wherein the multi-functional epoxide has an epoxide equivalent weight of 50 grams to 4000 grams. 7. The epoxy endcapped adduct composition of claim 5 , wherein the multi-functional epoxide is selected from the group consisting of an aromatic epoxy, an alicyclic epoxy, an aliphatic epoxy, or a combination thereof. 8. A curable composition comprising: the epoxy endcapped adduct composition of claim 5 and a curing agent, wherein the epoxy endcapped adduct composition and the curing agent are combined in a molar ratio of 0.85:1.0 to 1.0:0.85 moles of epoxy endcapped adduct functionalities to moles curing agent functionalities. 9. The curable composition of claim 8 , wherein the curing agent selected from the group consisting of an anhydride, an amine, a phenolic, or a combination thereof. 10. A product formed by curing the curable composition of claim 8 .
