Abstract

1331197 Resin-impregnated foil BRITISH INDUSTRIAL PLASTICS Ltd 27 Jan 1972 [2 Feb 1971] 3652/71 Headings D1P and D2B A resin-impregnated foil is made by impregnating an absorbent sheet with an aqueous solution of a latent acid catalyst, electrostatically depositing a thermosetting resinous material thereon, and pressing the latter material into the sheet. The absorbent sheet may be a woven; knitted, or non-woven material e.g. paper. The latent acid catalyst may be MgCl 2 , Zn(NO 3 ) 2 , Al 2 (SO 4 ) 3 , or propanolamine hydrochloride. A plasticiser may be included in the aqueous solution of the latent acid catalyst. The resinous material may be powdered melamine-formaldehyde resin optionally containing modifying additives such as condensation products of formaldehyde with a guanamine derivative or 2-cyclohexyl-4, 6-diamino-s-triazine, and dimethylol ethylene urea.
