Retroreflective articles include a layer of optical elements, and a polyurethane bead bond layer. The optical elements include transparent microspheres, and at least one reflective layer. The polyurethane bead bond layer is the reaction product of a reaction mixture of at least one aliphatic polycarbonate polyol and at least one polyisocyanate, and the reaction mixture is free of polyols containing unsaturated groups. The retroreflective articles have improved wash durability.

A wet cylinder liner for internal combustion engines may include a cylindrical body composed of a ferrous alloy having a circumferential outer surface. The cylindrical body may include a first layer and a second layer disposed sequentially on the outer surface. The first layer may include at least one of at least one silicon and at least one two-component epoxy adhesive. The second layer may include a silane-elastomer compound. The silane-elastomer compound may include nanoparticles of silicon oxide and an adhesion modifier additive. The second layer may be configured as an interface between a cooling fluid and the first layer, as well as to resist erosion by cavitation. The first layer may facilitate an interface for resistance at high temperatures.

A coating, in particular a coating for a back side of a brake pad opposite a braking side, includes a pair of bonding layers and a composite layer. Each of the bonding layers includes an epoxy material. The composite layer is disposed between the pair of bonding layers, and includes a mixture of a rubber material and particles of a secondary material. A method for forming the coating includes coating a layer of epoxy onto the surface to be coated to form a first bonding layer, coating the mixture of the rubber material and particles of a secondary material onto the first bonding layer to form a composite layer, coating a layer of epoxy to the composite layer to form a second bonding layer, and then curing the coating via a curing process.
