A building element () that is suitable for use as a structural element in wet areas or external docking. The building element () comprises a rigid substrate () having an upper face (). Over the first face () lies a radiation curable resin () into which a layer of reinforcing material () is at least partially embedded. The reinforcing material () and resin () can be applied separately or together onto the first face () of the rigid substrate () or in some cases can be applied to both faces. An apparatus and method for producing the building sheet are also disclosed.

A cementitious composite article incorporating a powder coating on at least one surface is provided. The composite article includes a surface treatment adapted to facilitate application of the powder coating onto the article. The surface treatment can include modifications to surface porosity, surface, and/or application of a sealer to the surface so as to make the cementitious surface more conducive to powder coating. One method of manufacturing the cementitious composite article includes first applying a sealer coating to a surface of a fiber cement substrate, partially curing the substrate to a gel-like state, applying a powder coating to the article, processing the article to a curing device in which the powder coating and sealer coating are co-cured to form a hardened film.

Composite cement article incorporating a powder coating and methods of making same

A composite building article is configured with one or more subsurface interfacial zones provided to improve the durability of the article. Each subsurface interfacial zone is made of a matrix of fiber cement and radiation curable material. The radiation curable material forms an interlocking network with the fiber cement to provide a interfacial zone against ingress of environmental agents that can degrade the article. The number, configuration and distribution of the subsurface interfacial zones can vary dependent on the desired characteristics of the final product. The subsurface interfacial zones also improves the adhesion between exterior coatings and the substrate as the interfacial zones can be integrally formed with the substrate as well as exterior coating layer.

This invention relates to non-aqueous formulations comprising resins and/or polymers with a higher solids content and a solvent which is a diether of the general formula: R.O.R..sup.1.O.R.sup.2, wherein each of R, R.sup.1 and R.sup.2 is a straight or branched chain, saturated aliphatic hydrocarbyl group having from 1 to 5 carbon atoms and in which R and R.sup.2 are the same or different alkyl groups and wherein R.sup.1 is an alkylene group, said formulation containing less than 25% w/w of solvents or diluents having free hydroxyl groups. The formulations are particularly useful in vehicle refinishes.
