Methods of producing an elastomer are disclosed that include (I) applying an actinic radiation curable composition preferably selected from a urethane (meth)acrylate, an allophanate urethane (meth)acrylate or a lactone-containing (meth)acrylate to a substrate at a thickness of at least 0.25 mm (10 mils); (II) exposing the composition ultraviolet radiation to produce a cured film; and (III) removing the film from the substrate. Related compositions are also disclosed.

Methods for making elastomers, elastomer compositions and related elastomers

A process of directly coating a metal substrate and curing the coating using radiation sources such as UV radiation having a wavelength of 200 nm and above. Furthermore, compositions of the invention can be used as a tie-coat for coatings that do not bond well directly to various metal substrates.

Direct-to-metal radiation curable compositions

The present disclosure is directed to a process for forming a reinforced ultraviolet (UV) radiation-curable composite. The composite may be formed by applying reinforcing layers and resin layers to a substrate. The resin composition may include an aliphatic urethane acrylate oligomer, a polyfunctional acrylate monomer, and a photoinitiator. The composite formed on the substrate may be exposed to UV radiation to cure the composite on the substrate. The composite may be characterized in that it is cured within 10 minutes of exposure to UV radiation and does not exhibit oxygen inhibition effects, such as, for example, surface tack. The reinforced UV-curable composite may find utility, for example, as a rapid field repair patch in aerospace applications, among others.
