A method of applying a curable powder coating, to a selected portion of a spin-on filter housing, uses a fluidized bed coating apparatus to provide a slip-resistant enhanced gripping surface when cured. This slip-resistant coating is applied to a selected portion of the exterior surface of the filter housing, in order to provide an easily grippable slip-resistant textured surface, once the powder has been cured. The textured coating according to the invention may be applied to a bare untreated plastic or metal surface, or alternatively, may be applied overlapping a cured layer of a conventional coating. A preferred coating is a thermosetting paint powder. In a first embodiment of the invention, a slip-resistant textured surface coating may be applied to the entire exterior surface of a spin-on filter housing, except the base plate thereof. In a second, preferred embodiment of the invention, it is desirable to limit the application of the above-described slip-resistant powder exclusively to a designated area, and to clean the area where the added powder is not wanted, in order to remove any extraneous powder from the remainder of the filter surface, and to present a visually appealing finished product. A spin-on filter having a slip-resistant textured gripping surface, which is a product of the described process, is also described.

A filter element is assembled by first fixturing the parts together so that the assembly may be manipulated by automated assembly equipment before the end cap sealant is fully cured in an oven which is off-line from the automated assembly equipment. In one embodiment, a plastisol sealant is used, which is "kiss-gelled" by rapidly increasing the temperature of the sealant for a few seconds to cure the sealant sufficiently to permit the assembly to be handled but without fully curing the sealant. The end cap on the other end of the assembly is then installed and kiss-gelled before the completed (but uncured) assembly is transferred to a curing oven where the plastisol at both ends of the assembly is fully cured at the same time. In another embodiment of invention, a small bead or band of an ultravioletly cured polymer sealant is dispensed against adjacent the centertube of the assembly and the ends of the inner tips of the pleats, and a band of conventional plastisol sealant is dispensed on the rest of the end cap. The ultravioletly cured polymer is then cured by ultraviolet light to permit the partially completed assembly to be inverted and a similar end cap installed on the opposite end, before the completed (but uncured) assembly is transferred to an off-line curing oven where the plastisol is fully cured.
