Claims28
An energy curable bonding resin composition to prevent corrosion in bonding metallic optical structures comprising:
- at least one monomer;
- acrylated epoxidized soya bean oil;
- and
- a photoinitiator selected from among 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO);
- phosphine oxide, phenylbis 2,4,6-trimethyl benzoyl;
- oligo[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone];
- difunctional alpha-hydroxy ketone, and combinations thereof;
- wherein the amount of epoxidized soya bean oil is less than 60% by weight of the resin composition;
- and wherein at least one photoinitiator is a difunctional alpha-hydroxy ketone;
- and wherein the bonding resin is an adhesive for bonding the metallic surface of a first optical quality substrate to the metallic surface of a second optical quality substrate;
- and wherein the bonding resin prevents corrosion of the metallic surfaces of the optical substrates.
The method of 15, wherein the curing is performed with an electron beam.
A method of manufacturing an energy curable resin composition for use in bonding a metallized optical structure comprising the steps of:
- providing a monomer:
- dispersing an oligomer of epoxidized soya bean oil with the monomer;
- and
- dispersing a photoinitiator selected from the group consisting of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide (TPO);
- phosphine oxide, phenylbis 2,4,6-trimethyl benzoyl;
- 0ligo[2-hydroxy-2-methyl-1-[4-(1-ethylvinyl)phenyl]propanone], and Alpha-hydroxy ketone, difunctional with the monomer and epoxidized soya bean oil;
- wherein the amount of epoxidized soya bean oil is less than 60% by weight of the resin composition;
- and wherein at least one photoinitiator is a difunctional alpha-hydroxy ketone;
- and wherein the bonding resin is an adhesive for bonding the metallic surface of the first optical quality substrate to the metallic surface of a second optical quality substrate;
- and wherein the bonding resin prevents corrosion of the metallic surfaces of the optical substrates.
