We consider that these new formulas are "non-hazardous".
It is true to say that all water based coatings require a small percentage
of co-solvent for them to work properly. The co-solvents we use are, to our
knowledge, on the US EPA VOC exempt list. Their proportion is generally far
less than 3% by volume.

Hi Graham.
Not commenting on the newer formulations that Graham references, the over
spray of most water based, VOC free coatings is a fire hazard, according to
our insurance and fire inspectors.
