  • Heat-resistant roll and method of making same
    Patent number: 4632855
    Abstract: The useful life expectancy of an RTV roll for use especially in the fuser of a copying machine is increased considerably by applying a silazane resin polymer coating to the surface of the roll and heating the coated roll to an elevated temperature sufficient to cure the resin and bond it to the roll surface so that it forms a flexible adhesive covering on the roll which minimizes the adherence to the roll of toner particles and copy paper.
