In terms of chemical properties, methyl silicone resin and phenyl silicone resin have different reactivity. Due to the strong electron donating property of phenyl group, phenyl silicone resin has higher reactivity and is more likely to participate in chemical reactions. Therefore, phenyl silicone resin has more advantages in certain occasions that require high reactivity. Methyl silicone resin has relatively low reactivity due to the weak electron donating property of methyl group, but it performs well in some other aspects.
