Abstract: A curable composition that includes a urethane multifunctional (meth)acrylate, an inorganic filler having a primary particle dimension of at least 200 nm, a photoinitiator system that can be activated by electromagnetic radiation in the range of 340-550 nm, a reactive diluent, and a reinforcing silica having a primary particle dimension of 100 nm of less. The sum of the absolute value of the difference in the refractive index of the filler and the refractive index of the composition cured without filler plus the birefringence of the filler is 0.054 or less, i.e. 0.054≥|nfiller−nmatrix|+δfiller, where nfiller is the refractive index of the filler, nmatrix is the refractive index of the composition cured without filler, and δfiller is the birefringence of the filler.

Abstract: A dual curable thiol-ene composition comprising a polythiol, an unsaturated compound, a photoinitiator, an organic hydroperoxide (thermal initiator) and optionally a nitrogen-containing base, such as e.g. an N-heterocyclic compound (together with the organic hydroperoxide a redox initiator system). A cross-linked polymer prepared therefrom. A method of making such a polymer. A cured sealant comprising such a polymer. The sealant is preferably for use in aerospace.

Abstract: Provided are sealant compositions that include a first component and second component. The first component contains a polysulfide, a polythioether, or a copolymer or combination thereof containing pendant or terminal thiol groups, while the second in component contains an ethylenically-unsaturated compound and either the first or second component further contains a photoinitiator. Alternatively, the second component can contain a polyepoxide and either the first or second component can contain a photolatent base and a photosensitizer. The first or second component further contains a colorant that substantially reflects or substantially transmits light over the wavelength range from 350 nm to 500 nm. These compositions can provide cure-on-demand sealant formulations that comply with Class B sealant regulations on color, provide an acceptable depth of cure, and allow two-part mixing to be easily distinguishable.

Abstract: A lightning protective seal cap comprising a seal cap that defines an interior, and a quantity of an uncured sealant that is curable by the application of actinic radiation so as to bind the seal cap to a fastener. The interior of the seal cap contains the quantity of uncured sealant, the seal cap is positionable over the fastener such that at least a portion of the fastener resides in the interior of the seal cap, and when the seal cap is in position over the fastener, the sealant containing seal cap prevents electrical arcing to the fastener from a lightning strike.

Abstract: Methods of bonding together substrates that do not require use of primers, mixing, fixturing, or autoclaving. These methods can include the steps of disposing an adhesive layer on a bonding surface of either substrate, the adhesive layer comprising a curable composition that is dimensionally stable at ambient conditions; either before or after disposing the adhesive layer on the bonding surface, irradiating the adhesive layer with ultraviolet radiation to initiate curing of the curable composition; placing one substrate so as to be bonded to the other substrate by the adhesive layer; and allowing the adhesive layer to cure.

Abstract: A curable composition is provided comprising a urethane (meth)acrylate oligomer, a urethane (urea) phosphonate adhesion promoter, optionally reactive diluents, and an initiator. The use of the urethane (urea) phosphonate adhesion promotor provides better ageing stability and adhesion, as measured by T-peel adhesion test, than the use of other conventional adhesion promotors.
