Abstract:
Objactive:To study the color changes of SY-1 silicone elastomer before and after polymerization.Methods:L*a*b*color parameters of 10 samples of SY-1 silicone elastomer were measured with Minolta chroma-ticity instrument(CS-321) before and after polymerization.The color difference(△E) between precure and post-cure was calculated as△E =[(△L)2+(△a)2+(△b)2]1/2.Results:After polymerization L*and a*valueswere increased(P
