Disclosed are methods of protecting porous substrates and/or increasing the peel-resistance of coatings and stains for porous substrates. The methods may include providing a stain or coating comprising a microencapsulated self-healing material; and applying the stain or coating to a porous substrate. Damage to the stain or coating may release the self-healing material at a site of damage, such as a crack or scratch in the stain or coating. The self-healing material may be a polymeric precursor, .an unsaturated polyester resin or alkyd, a fatty acid-based natural oil or derivative thereof, or a cross-linkable silane or siloxane monomer or resin. The microencapsulated self-healing material may include a microcapsule having a shell wall that includes a thermosetting polymer or a thermoplastic polymer; the thermosetting polymer may include urea-formaldehyde, melamine formaldehyde, polyurethane, polyurea, or polyacrylate; and the thermoplastic polymer comprises poly(methyl methacrylate), poly(lactic acid), or poly(glycolic acid).

Disclosed is a method for recoating an RTV anti-pollution flashover coating on an insulator coated with the RTV anti-pollution flashover coating. The insulator includes an insulator body, a steel cap connected to an upper surface of the insulator body, and a steel pin connected to a lower surface of the insulator body. The method includes: (1) wiping off dirt on a surface of the insulator; (2) determining whether the insulator can be recoated; (3) performing coating by using an RTV anti-pollution flashover coating with the content of solid being 55%-65%. After coating is performed, a newly coated anti-pollution flashover coating can be closely adhered to a surface of the insulator, swelling does not occur, adhesion of the coating with respect to the insulator is not reduced, the hydrophobicity of the surface is recovered, and non-reduction of a pollution flashover voltage of the insulator is ensured.

An apparatus for applying an asphalt binder composition to a roadway during construction or repair of an asphalt pavement which apparatus include: a mobile vehicle having a chassis extending in a longitudinal direction which longitudinal direction is aligned with a forward/rearward direction of travel of said mobile vehicle; at least one storage tank supported on the chassis containing an asphalt binder composition; and at least one spray nozzle configured to dispense the asphalt binder composition from the at least one storage tank in a longitudinal strip or band having a width that is no greater that a width of the asphalt binder composition dispensed by one of the at least one spray nozzle. The at least one spray nozzle can include a plurality of spray nozzles that are coupled to a common spray bar. According to one embodiment the asphalt binder composition is a void reducing asphalt membrane composition that is provided between adjacent asphalt pavement passes.

Coatings for filling cracks within anodic films formed from, for example, a laser marking process are described. The cracks generally have widths of nanometers in scale and can extend from an external surface of an anodic film to an underlying metal substrate. The coatings fill the cracks to prevent liquid and contaminants from entering the cracks and reaching the metal substrate, thereby preventing corrosion of the underlying metal substrate. The coatings can be hydrophobic such that water is wicked away from the cracks. In some cases, the coatings are fluoropolymer coatings. Methods include spray-on techniques that provide a thin and uniform layer of the coating. The spray-on technique can be configured to spray on a fluoropolymer precursor onto the anodic film such that the fluoropolymer precursor diffuses into and polymerizes into the fluoropolymer coating within the cracks.

A radiation system includes a radiation device coupled to a control unit; a radiation blocker having an adaptor opening for receiving the radiation device when the radiation device is positioned on the radiation blocker; and a carrier comprising a first compartment for housing the radiation blocker and, a second compartment for housing the control unit. The adaptor opening can dimensionally fit the radiation device to block radiations from the radiation device when the radiation device is positioned in the radiation blocker. The radiation device can produce radiation having peak radiation wavelength in a range of from about 250 nm to about 450 nm and can have a peak irradiation power in a range of from about 0.5 W/cm.sup.2 to about 10 W/cm.sup.2.
