... are in general agreement with the findings of Aulton et al. (1981) and, interestingly, Porter used a technique whereby the film for investigation was obtained by spraying and not by casting. ... • Increase in strain or film elongation • Decrease in elastic modulus • Decrease in tensile strength. Page 22 Furthermore, Delporte advocated the use of elevated temperature coating media in ... parameter, δ. Equation (2. 4) can then take the following form: ΔH=Vm(δ1−δ 2 ) 2 1· 2 (2. 5) From equation (2. 5), if δ1 and δ 2 are the same, the heat of mixing will be zero, which...
