fillers, putties, plasters, modelling clay.
Release to the environment of this substance can occur from industrial use:
formulation of mixtures.
Other release to the environment of this substance is likely to occur from:
indoor use and
outdoor use resulting in inclusion into or onto a materials (e.g. binding agent in paints and coatings or adhesives).
Article service life
Release to the environment of this substance can occur from industrial use:
industrial abrasion processing with low release rate (e.g. cutting of textile, cutting, machining or grinding of metal) and
of articles where the substances are not intended to be released and where the conditions of use do not promote release.
Other release to the environment of this substance is likely to occur from:
outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials) and
indoor use in long-life materials with low release rate (e.g. flooring, furniture, toys, construction materials, curtains, foot-wear, leather products, paper and cardboard products, electronic equipment).
This substance can be found in products with material based on:
stone, plaster, cement, glass or ceramic (e.g. dishes, pots/pans, food storage containers, construction and isolation material),
