Abstract
Compositions having a curable unsaturated compound, an adhesion promoter and curing agent which have a peak exotherm of less than 50° C. are disclosed. The compositions when cured are flexible bioadhesives which are also disclosed. Non-curable diluents can be included in the compositions. Flexible bioadhesives formed on biological structures and having low peak exotherms upon curing of curable compositions to form the flexible bioadhesives are disclosed. Compositions having a curable unsaturated compound and a curing agent and a peak exotherm of less than 50° C. are included in the invention.
Claims37
A composition comprising:
- a compound having an unsaturation index of at least about 500;
- a curing agent;
- and
- an adhesion promoter,
- wherein the composition is curable and has a peak exotherm of less than about 50° C. (120° F.).
A two part system comprising:
- a) a first part which comprises a curing agent;
- and
- b) a second part which comprises a curing agent synergist of the curing agent of the first part,
- wherein the first part or the second part or both further comprises a compound having an unsaturation index of at least 500 and an adhesion promoter and wherein upon mixing of the first part and the second part, curing is achieved with a peak exotherm of less than about 50° C. (120° F.).
A method for forming a flexible bioadhesive on a tissue, comprising:
- contacting the tissue with a composition comprising a compound having an unsaturation index of at least about 500, a curing agent and an adhesion promoter, wherein the composition is curable and has a peak exotherm of less than about 50° C. (120° F.), and
- curing the composition to form the flexible bioadhesive on the tissue.
A composition comprising a methacrylated polyetherurethane oligomer, capric/caprylic triglyceride, polycarbophil, camphorquinone, and ethyl-4-dimenthylaminobenzoate.
A composition comprising a compound having less than about 40% monomers, an unsaturation index of at least about 500, a curing agent and an adhesion promoter, wherein the composition is curable and has a peak exotherm of less than about 50° C. (120° F.).
A method of making a composition comprising the steps of:
- selecting a compound having an unsaturation index of at least 500;
- and
- mixing said compound with a curing agent and an adhesion promoter, wherein the mixture is curable and has a peak exotherm of less than about 50° C. (120° F.).
