If anyone is looking for a silicone ingredients supplier in Toronto, I just came across this one:
Excellent selection of various silicones with a brief description of what each silicone's intended use is. Even if the dispatch size is too large for most formulators - 20kg, the information resource this link provides is worth it.
I find if you call these suppliers, they can often clear up questions you have regarding the type of products they distribute.
I am dealing with a manufacturer in Toronto that requires 400kg minimum batch sizes, so the 20 kg unit would be doable for me as it represents only 5% of any particular silicone ingredient in my formula.
