Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A method for treating a panel of wood-based material to achieve an adhesive-free surface after a decoration (2) has been printed onto at least an upper side of the panel of wood-based material, is distinguished by the fact that a cellulose-free top layer (3) of melamine resin with mixed-in glass beads (5) is applied to the decoration (2), and this top layer (8) is dried before a wear-resistant layer (6) is applied to the top layer (8).

A method is used to provide an electrically-conductive polyaniline pattern by providing a uniform layer of a photocurable composition on a substrate. The photocurable composition comprises a water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The photocurable composition is exposed to cause crosslinking via [2+2] photocycloaddition of the (b) recurring units, thereby forming a crosslinked polymer. Any remaining water-soluble reactive polymer is removed. The crosslinked polymer is contacted with an aniline reactive composition having aniline monomer and up to 0.5 molar of an aniline oxidizing agent, thereby forming an electrically-conductive polyaniline disposed either within, on top of, or both within and on top of, the crosslinked polymer.

The present invention relates to a dye-sensitized solar cell including a working electrode (1), a first conducting layer (3) for extracting photo-generated electrons from the working electrode, a porous insulation substrate (4) made of a microfibers, wherein the first conducting layer is a porous conducting layer formed on one side of the porous insulation substrate, a counter electrode including a second conducting layer (2) arranged on the opposite side of the porous substrate, and electrolyte for transferring electrons from the counter electrode to the working electrode. The porous insulation substrate comprises a layer (5) of woven microfibers and a layer (6) of non-woven microfibers disposed on the layer of woven microfibers. The present invention also relates to a method for producing a dye-sensitized solar cell.

A method of curing a curable composition includes contacting the free-radically curable composition with the solid primer layer thereby causing at least partial curing of the curable composition.

A coating process includes the successive steps of preparing the zone to be treated. At least one coat of a primer is applied to the prepared zone to obtain a thickness ranging from 100 to 450 micrometers. The zone to be treated is then reconditioned and a least one top coat is applied to obtain a thickness ranging from 100 to 450 micrometers.
