Abstract
The present invention provides a repair resin composition for repairing breaks in a vehicle windscreen and curing units for curing the repair resin after it has been inserted into the break. The present invention also provides a method of repairing a vehicle windscreen, comprising inserting a resin into a repair zone, wherein the resin comprises a photoinitiator that activates when exposed to light of an activation wavelength, wherein the activation wavelength is between 370 nm and 425 nm, and curing the resin by emitting light including light within the activation wavelength range onto the repair zone.
Claims24
A method of repairing a vehicle windscreen, comprising:
- inserting a repair resin into a repair zone, wherein the resin includes a photoinitiator that activates when exposed to light of an activation wavelength, wherein the activation wavelength is between 370 nm and 425 nm;
- and
- enhancing curing of the resin by emitting light including light within the activation wavelength range onto the repair zone.
A curing unit for use in repairing a vehicle windscreen, comprising:
- a mount apparatus for securing the curing unit to the windscreen;
- and
- a light emitter configured to emit light onto a repair zone, wherein:
- a) the mount apparatus is spaced at least 10 cm away from the light emitter;
- the light emitter being mounted by means of a rigid arm which is not able to deflect or bend;
- and/or
- b) the light is emitted by an LED device and is rated to emit at a single rated wavelength;
- and the device is capable of only emitting at that rated wavelength (other than any leakage wavelengths above and below the rated LED wavelength).
A windscreen repair resin composition comprising:
- 30 to 80% wt acrylates;
- 4 to 25% wt acids;
- 0.5 to 10% wt oxysilanes;
- and
- 1 to 10% wt UV activated photoinitiator.
