The deposit material further includes 1-30% (wt.) of urethane acrylate, 1-30% by weight of reactive diluent, photoinitiator and 1-10% (wt.) of rheological adsorbing additive. Optimally, the adhesion promoter is added after the other components have been mixed with the rheological additive.

Patent number: 8779022Abstract: Conventional curable polymers tend to shrink upon curing whilst low shrinkage ultraviolet light curing polymers have a problem with respect to curing below surface areas of a component. By providing light transmitting elements and/or local ultraviolet light source precursors, greater depth of ultraviolet curing can be achieved and therefore enhanced acceptability with regard to component manufacture. The light transmitting elements may be formed by optic fibers or coatings to existing reinforcing fibers or through consideration of the refractive index of the cured and uncured polymer to create light transmission paths through the component. Ultraviolet light source precursors can be activated by heat or a “seed” light exposure or vibration to create localised ultraviolet curing of the polymer thereabout.Type: GrantFiled: June 3, 2008Date of Patent: July 15, 2014Assignee: Rolls-Royce PLCInventor: Ian Colin Deuchar Care
