ABSTRACT:
Manufacture of an article incorporating a thermosetting-powder surface-coating includes bonding a component of the article to the coating by contacting the melted powder with the component before curing takes place, and maintaining it in contact through curing. In a glass architectural panel, an aluminium foil is bonded in this way to a polyester/triglycidyl-isocyanurate powder coating on the silane-primed back of the facing glass; the metal foil is backed by a plastics or rubber open-cell material to enhance resistance of the glass to impact, and also, together with the foil, resistance to thermal shock. The coating includes pigmentation to give the effect of colored glass, or is clear to allow the contact-surface of the metal to show through; further decorative effect is obtained by pigmentation variation in the coating and/or partial metallization of the glass back-surface. The technique is also applied to bonding fittings to the powder-coated face of a door; of decals of cured powder-coating material to, or within, powder-coatings; of glass over apertures in metal walls; and of glass to glass in building up a laminate.
