Although we’ve stocked their products for several years in our warehouse in London E4, since 2016, we’ve acted as the main distributor/agent in the UK for the market-leading, German Sealant & Adhesive company OTTO-CHEMIE. Subsequently our range of Otto Chemie products has increased massively to include a huge range of OTTOSEAL® coloured mastic silicone sealants for specialist internal & external applications as well as OTTOCOLL® Adhesives and various branded tools & accessories. Very popular, solid and unquestionably reliable, their products are the results of a company with a long history spanning more than 125 years. From a Berlin putty-manufacturing company in 1881, Hermann Otto evolved into a powerhouse producer of silicone sealants & adhesives in the early 1960s.
