How do I determine the correct canisters to use in my respirator for spray application of the Poly-Fiber Epoxy Primer? Is there some sort of reference table that specifies the type of canister for certain chemicals or classifications of paint (I couldn't find anything online)? The epoxy primer contains a host of different chemicals (approximately 16). I have been using the canisters that came with my multi-contaminant respirator (they have a green label with a NIOSH 03121E number on them), but I got to wondering if they are providing adequate protection.
