Safety & Health

Caution Measures

Our products can be processed safely, provided that the usual precautions for handling chemicals are observed.Uncured materials should be kept away from food. To avoid allergic reactions, it is strongly recommended to wear impermeable rubber or plastic gloves and safety goggles. Hands must be thoroughly washed with warm water and soap after each use. The use of solvents should be avoided. Afterwards, the skin should be dried with disposable paper towels – not textiles. The work area should be well ventilated; an extraction system above the workstation may be required. A description of all precautionary measures is included in the safety data sheets for the individual products. We will be happy to send these to you upon request.
