Claims6
A light curable composition comprising:
- a. a light curable component comprising a backbone selected from the group consisting of (meth)acrylates, epoxies, polyisobutenes (PIB), polyurethanes (PU), polyolefins (PO), ethylvinylacetates (EVA), polyamides (PA) and combinations thereof;
- and a light curing moiety;
- b. a cure system;
- and
- c. a rheology modifying component present in an amount of about 30% to about 50% by weight of the total curable composition;
- wherein the light curable composition has a Thixotropic Index (TI) (cp at 1 s−1/cp at 10 s−1) of between about 2 and about 15.
