A resin for a binder suitable for mineral fibers such as glass or stone wool, said resin comprising the reaction product of a polymer free mixture of an amine with a first anhydride and a second aromatic anhydride, characterized in that the first anhydride and the second aromatic anhydride are different anhydrides.
A resin comprising a polymer free mixture for a binder, said resin comprising the reaction product of a cyclic anhydride and an amine, at a pH of from about 2.5 to about 4.2, said pH being predetermined to positively influence the curing speed of the resin, wherein said cyclic anhydride comprises a first anhydride and a second aromatic anhydride that is different from said first anhydride.
A method for providing a polymer free resin for a binder suitable for binding mineral fiber products, said process comprising the steps of mixing together under reaction conditions an amine with a first aliphatic cyclic anhydride and a second aromatic cyclic anhydride.
A resin for a binder suitable for mineral fibers, including glass or stone wool said resin comprising the reaction product of a polymer free mixture of an amine with a first anhydride and a second aromatic anhydride, characterized in that the first anhydride and the second aromatic anhydride are different anhydrides, and wherein flowtime of said resin is reduced by at least a factor of two as contrasted with a binder composition having only one anhydride.
A resin comprising a polymer free mixture for a binder, said resin comprising the reaction product of a cyclic anhydride and an amine, at a pH of from about 2.5 to about 4.2, said pH being predetermined to positively influence the curing speed of the resin, wherein said cyclic anhydride comprises a first anhydride and a second aromatic anhydride, and wherein flowtime of said resin is reduced by at least a factor of two as contrasted with a binder composition having only one anhydride.
