Abstract
Substrates suitable for optoelectronic display devices are prepared by: (a) applying a liquid silicone optical bonding agent to a first substrate, (b) activating the liquid silicone optical bonding agent applied in step (a) by irradiation with light in a wavelength range of 200 nm to 500 nm, wherein the duration of the irradiation is less than the gel time of the liquid silicone optical bonding agent, and (c) applying a second substrate to the activated liquid silicone optical bonding agent before the liquid silicone optical bonding agent is gelled.
Claims14
A method for laminating substrates, comprising the steps of:
- a) applying a liquid silicone optical bonding agent to a first substrate,
- b) activating the liquid silicone optical bonding agent applied in step (a) by irradiation with light of a wavelength in the range of 200 nm to 500 nm, wherein the duration of the irradiation is less than the gel time of the liquid silicone optical bonding agent,
- c) applying a second substrate to the activated liquid silicone optical bonding agent before the liquid silicone optical bonding agent is fully gelled, wherein
- the liquid silicone optical bonding agent is an irradiation curable one-component silicone material free of acrylic units, comprising the ingredients i) a polysiloxane containing at least two alkenyl groups, ii) a polyhydrosiloxane having on average at least two SiH groups per molecule, iii) a silicone resin different from ingredients i) and ii), iv) an oxide filler with BET surface area between 80-400 m2/g, and v) a photoactive platinum catalyst.
