Abstract
The present invention generally relates to a system and method for using a volatile organic compound (VOC) free low radiant flux LED UV curable composition, and more particularly to unique and novel uses of the composition such as one or two or more of a fire retardant, clear coat, composite material, resin, top coat, improved holdout coating, a sealant coat, and combinations of the same.
Claims21
A method of repairing at least a portion of a damaged pipe, comprising:
- preparing at least a portion of the damaged pipe for repair;
- arranging a composite material that is substantially saturated with a VOC free low radiant flux UV curable composition on at least a portion of the damaged pipe;
- applying an energy source having a wavelength in a range from 360 nm to 420 nm and a radiant flux at a surface of the substantially saturated composite material of 100 mW/cm2 or less to cure at least a portion of the substantially saturated composite material,
- wherein the VOC free low radiant flux UV curable composition comprises:
- an acrylate monomers/oligomers;
- a thiol monomers/oligomers;
- a photo initiator;
- and
- a radical inhibitor.

A method of repairing at least a portion of a damaged pipe, comprising:
- preparing a portion of the pipe for repair;
- applying a VOC free low radiant flux UV curable composition to a composite material to substantially saturate the composite material, wherein the composite material has internal surface, an external surface, a first end, a second end separated from the first end, and a lumen that extends from the first end to the second end;
- arranging an inflatable member in the lumen of the saturated composite material;
- inflating a portion of the inflatable member to expand the statured composite material to be at least substantially adjacent to an interior surface of the pipe;
- applying an energy source having a wavelength in a range from 360 nm to 420 nm and a radiant flux at a surface of the saturated composite material of 100 mW/cm2 or less to at least partially cure the saturated composite material;
- wherein the VOC free low radiant flux UV curable composition comprises:
- an acrylate monomers/oligomers;
- a thiol monomers/oligomers;
- a photo initiator;
- and
- a radical inhibitor.
