These silicones can be inhibited by sulphur, nitrogen, amino compounds and metal salts. If you are unsure whether the products you are using (including gloves, spatulas and cups) contain these ingredients, please do a small test first. These substances are found in many latex gloves, some plasticines, paints and adhesives, condensation-cure silicones, 1-component silicone sealants, natural rubbers and 3D printing materials (especially stereolithography).
