Vapour degreasing is an excellent way to obtain highly clean surfaces. The efficiency of cleaning can be checked by determining the coefficient of friction, in addition to dark-field-inspection, contact-angle and thin-film-adhesion measurements methods. High values are typical for clean surfaces [7].

Comparison of Adhesion Properties Subjected to Ordinarv-and Over-Vulcanization. For RFL coated nylon 6 and 66 fibers used in tire cords, the reduction of adhesion properties, caused by overvulcanization was small and comparable to that subjected to the ordinary vulcanization. In the case of the armid fabric samples coated with the nylon thin films, adhesion properties such as peel strength and rubber coverage obtained after the overvulcanization were relatively high regardless of the nylon type, though a reduction was observed in some cases, as shown in Figure 7. 

A simple form of the scratch test is used for assessing paint adhesion (see Paint constitution and adhesion). The scratch test, as described in this article, is perhaps best regarded as a useful comparative method of characterizing thin film adhesion. The test variables used should be carefully characterized and caution exercised in comparing results obtained in different laboratories.

Initial results, then, show a great promise for these perfluorin-ated thermoplastic resins as hot-melt, thin-film adhesives. Their unique set of physical and chemical properties gives them a range of applicability few other polymers can begin to match. Work with them should continue with emphasis on their role in water-impervious joints. Hopefully such an investigation should lead to a better understanding needed for their optimum utilization. 

Needed Test Methods. It is impossible to list, never mind discuss, all of the other methods that have been proposed for measuring adhesion. However, there remain serious needs, still unmet. One is for the accurate measurement of thin-film adhesion for example, in microelectronics and biomedical applications. A detailed review of this subject has been given by Mittal, but it appears that a generally sat-...
