SILISIL STM 835 Medical Silicone Spray
High-purity silicone oil spray based on dimethicone (in accordance with the European Pharmacopoeia) – developed for the stringent requirements of the pharmaceutical, medical, and food industries.
Detailed product description
SILISIL STM 835 is a transparent, non-greasy silicone oil aerosol that forms a durable, clean lubricating and separating film on plastics, metals, elastomers, and glass. Thanks to its pharmaceutical purity, it meets uncompromisingly high hygiene and safety standards. The stable film minimizes friction, prevents material wear, and facilitates the cleaning of sensitive equipment—from sterile filling lines to production facilities in food technology.
Key advantages at a glance
