Is Acrylic paint toxic???

[williah]

I was skimming articles and threads and I think I read briefly that Acrylic paints might be proving to be toxic.

Is this true? Does anyone know? I'm going to be spraying my tubes, hoses, etc with a waterproof paint to cut down on algae growth. I'm also going to be waterproofing my stand. I just want to check before making a big mistake.

Thanks.

The 100% pure acrylic paints seem to be non-toxic to higher animals such as mice, rats, rabbits, etc. I have not seen any tests completed using aquatic organisms. The colors associated with many of these paints do contain heavy metals. Many manufacturers add biocides to their paint to help prevent build-up of algae, mold and mildew which would be toxic. It can be difficult to determine exactly what the manufacturer actually adds to their paint without consulting them.

DO you have an ingredient list?

Randy this MSDS sheet provides information for this brand, including the chemicals used for different colors:

MATERIAL SAFETY DATA SHEET
Utrecht Acrylic Paints
http://www.utrechtart.com/msds/docs/AAC.pdf

From this sheet:

Acrylic paints are formulated with acrylic binder, pigment and other proprietary components.
A typical formula may include 50% acrylic binder plus co-polymer, 30% pigment and 20%
proprietary ingredients.
Toxicity associated with pigments
Pigment toxicity reflects individual chemical components. These are noted in Appendix A.

Mars Black (PBk11) - No significant toxicity, (Iron oxide black).

The 20% proprietary ingredients can contain a lot of things.

If this paint is not used underwater, but only on the outside of hoses, etc, it is likely OK as long as it is not spray applied (which they say it shouldn't be).

So any suggestions on a different type of paint to use for hoses/boxes in the water?
