Abstract
A curable composition comprises at least one polymerizable compound and alpha-alumina particles. The alpha-alumina particles, taken as a whole, have a DV50 of less than 100 nanometers. The corresponding cured composition, and an abrasion-resistant article comprising an abrasion-resistant layer comprising the reaction product disposed on a substrate are also disclosed. A method that includes thermoforming the abrasion-resistant article is also disclosed.
Claims15
A curable composition comprising:
- at least one polymerizable compound comprising a (meth)acryl group, an isocyanato group, or combinations thereof;
- at least one curative for the at least one polymerizable compound, wherein the at least one curative comprises a free-radical initiator;
- and
- 0.1 to 10 percent by weight alpha-alumina particles based on a total solids weight, wherein the alpha-alumina particles, taken as a whole, have a Dv50 of less than 100 nanometers.
A polymerized reaction product of components comprising:
- at least one polymerizable compound comprising a (meth)acryl group, an isocyanato group, or combinations thereof;
- at least one curative for the at least one polymerizable compound, wherein the at least one curative comprises a free-radical initiator;
- and p1 0.1 to 10 percent by weight alpha-alumina particles based on a total weight basis, wherein the alpha-alumina particles, taken as a whole, have a Dv50 of less than 100 nanometers.
