Otopren® is a high-quality silicone used for same day earmolds or earplugs. Using an addition-vulcanizing and 1:1 mixture in a cartridge system (S-50), the consistency is smooth for a clean and precise surface quality making the impression/earmold easy to work with or modify in-office. We recommend to seal the surface of the earmolds with a soft silicone lacquer to achieve a smooth finish quality as well as to increase the anti-microbial properties.
