Everything You Need to Know About Pigment Green 7 for Coatings

Pigment Green 7

Pigment Green 7 is an organic pigment that’s widely used in water-based industrial coatings. It can be purchased from some major suppliers, or you can try to make it yourself with the recipe and instructions described below. Get ready to learn everything you need to know about Pigment Green 7 for coatings, including what it does, how it works, and why it’s so important for the paint you choose to use on your home or business building!

An Introduction to Pigment Green 7

PIGMENT GREEN 7, also known as pigment green earth or pigment green 36, is a calcium copper aluminium fluorosilicate that works as a colouring agent in coatings. It’s composed of chemical elements with varied applications and can be used in commercial and industrial paints and dyes. Pigment Green 7 is commonly seen in lighter green or bluish shades in its dye form, but can take on many hues when used as a pigment. For example, when tinted with blue it takes on an olive-brown shade while when mixed with yellow pigments it becomes more of a brown colour.

Safety Data Sheets and SDS

When it comes to choosing pigments and coatings, it’s not just about aesthetics. It’s also important that they be safe and free of health hazards. The rule of thumb is: If you can’t put your pigment or coating into a body cavity or internal organ, you should avoid using it. One way to do that is by purchasing materials that have undergone a safety screening process called safety data sheets (SDS). Any material with an SDS has been tested for carcinogenicity, mutagenicity, reproductive toxicity, and allergenicity—meaning that scientists have looked at all possible adverse health effects associated with exposure to it.

Properties and Uses of Pigment Green 7

The pigment green 7 is an organic compound, a pigment used in paints and some other products. It belongs to a class of substances known as phthalocyanine pigments. These are strong blue-green dyes with good stability on exposure to light and air. Plastic pigments are used in various products like coatings, plastics, textiles, etc. They have poor heat resistance which can make them crack or decompose at high temperatures or when exposed to sunlight over long periods.

Effects on Human Health

The long-term effects of using pigment green 7 are not yet known. In animal studies, two types of tumours occurred in treated mice—granulosa cell tumours and pituitary gland adenomas. The rate at which these tumours occurred was greater than would have been expected in animals not exposed to pigment green 7.

However, researchers point out that mouse models do not always accurately reflect what happens in humans. There is little evidence that exposure to pigment green 7 during pregnancy causes adverse effects on fetal development or fertility. But because little is known about potential health risks from the use of a particular substance, pregnant women should avoid contact with pigments whenever possible. A review published by CIR suggests that direct contact with pigments may be hazardous when certain manufacturing steps were omitted or done improperly.

Exposure Limits and Regulations in the EU

There are several European Union (EU) Directives and regulations regarding green pigments, including pigment green 7. The newest directive, CLP, categorizes pigments as either hazardous or not. In terms of safety classifications within CLP, green pigments in general fall under Risk Category 3: R36/37/38 – Harmful if swallowed. The old (and now defunct) European Directive 67/548 says that if a pigment is insoluble in water, it must be classified as hazardous with exceptions made for pigments in categories 1-7 and 13-15. Otherwise, a pigment will be non-hazardous.

Laboratory Testing Pigment Green 7

There are no known human health hazards associated with pigment green or its subcomponent copper complexes. Current information suggests that pigments based on copper chromate and pigment manufacturers in Gujarat do not pose a carcinogenic risk in humans. The American Conference of Governmental Industrial Hygienists (ACGIH) has designated both compounds as A3 – Not Classifiable as a Human Carcinogen. Additionally, CIB (Comité International des Associations de Fabricants d’Additifs Chimiques pour l’Industrie du Bâtiment), an association of building material manufacturers, has determined that some formulations of pigment green 7 and other additives containing transition metals may cause sensitization in certain individuals under specific exposure conditions.
