Types of Eco-Friendly Spray Paints
Non-toxic spray paint is that which is made from natural ingredients or that which has a Zero VOC of less than 5 grams per liter. Low VOC paints are also considered to be eco-friendly with their higher solid content that makes the paint less toxic.
Water based natural paints give almost no smell. An oil based natural paint on the other hand would contain natural aromatic compounds like citrus or other oils which give off a very pleasant smell. Because of this the paints would cause no allergies and be environmentally safe. Other ingredients in natural paints would include oils and resins obtained from plants, and other natural products like talcum, chalk and clay, whereas other additives would again be natural products like bees’ wax, natural latex, casein from milk, and other mineral dyes.
Paints with VOC lesser than 5 grams per liter, or Zero VOC paints, will still use some fungicides, biocides and colorants while a color tint can cause an elevated VOC. These paints are still considered non-toxic but are better avoided in places where children or babies may spend time.
Low VOC paints are those that use water as a carrier instead of any petroleum based products. This makes them less toxic than normal paints which are solvent based. Such non-toxic spray paints would have a VOC of below 50 grams per liter.
Milk paint is a paint that is water based and has been in use for centuries. Its ingredients are essentially milk, lime, pigments and borax. It however has a very short shelf life because of the milk content, but the paint is a favorite with the advocates of non-toxic paint.
