It was thus theoretically possible to protect nails or rivets from rust by hammering them into material coated with apfi; the film would remain intact between nail and support, cutting off most moisture.

Mr. Cromett combined heat-shrinkable material, color printers and graphics software programs to create a system that lets a user scan a photograph into a computer and print it on a heat-shrinkable material coated with an adhesive.

An early purpose of the support was to obtain a solid granular material coated with catalytic component, providing a hard and stable structure to withstand disintegration under gas or liquid flows.

They were skeletons of strong crisscross beams, with solid material between, coated with plaster.

They can be ferroelectric or, as mentioned above, made from a conducting material coated with an insulator, or electro-osmotically active particles.
