VOC requirements relaxing in CA?

Alex

I occasionally use ML Campbell solvent based products and could never get their slow reducer 2 (not CA VOC compliant) and a few months ago it showed up in the store.

Also, over the past few years I noticed the mineral spirits sold in the home centers caused oil based paint (i.e. Ben Moore alkyd SI) to dry very dull among other problems. I googled the mineral spirits product name + SDS and discovered it was 90% methanol which probably explains the difficulty. Eventually they labelled it mineral spirits substitute but I think they were adulterating it long before this.

I just bought a gallon of jasco mineral spirits and it seems to be the real deal, SDS says 100% Hydrotreated light distillate (petroleum) although the can part number is not on the SDS so cant be sure.

Anyone notice this?

Check and confirm products. I suspect that there's much incentive for manufacturers to use folks knowledgeable like bill about what may substitute for what else and make solventish products that are passable but can be sold in all markets.

Years ago, the well known George Wilson would finish the fine (now used in professional symphonies in boston, baltimore, etc) baroque hand made violins at CW with alkyd varnish from Sherwin Williams. They kept the labeling on the cans the same but adulterated the formula and his comment was that the varnish would not fully harden properly (I don't know what the overall consequence is, but he did mention that a trial with tru-oil looked great, but eventually a bridge would push through it and get all the way to the body of a violin. these days, you could probably sell the fact that the finish allowed "direct contact" between bridge and top).

At any rate, trust but verify
