Usually unnoticed in everyday life, but still indispensable! Sealants these days are crucial. They are used wherever joints, gaps or holes need to be sealed – in a very wide range of applications! With our product range of OTTOSEAL® sealants, we offer high-quality, made in Germany products that are perfectly tailored to your application areas.
Our product range has silicone, PU, hybrid & acrylic sealants, which each have specific characteristic profiles.
There are individual requirements for products depending on which area the sealants are to be used. After all, the sealant chosen should deliver the best possible quality and provide lasting, durable joints. Our OTTOSEAL® sealants are divided into 6 different categories and are true specialists in their respective application area.
Our product range of OTTOSEAL® sealants is as diverse as the application areas of sealants. To make it easier for you to choose the right product for your application, we have two practical consultation tools for you: the OTTO application assistant and the OTTO product filter!
The sealants should blend into the colours of the materials to be grouted as best as possible to achieve the most seamless end result possible. That is why we at OTTO produce many of our product from stock in numerous different colours. Our premium bathroom silicone OTTOSEAL® S 100, for example, is available as a standard in over 80 different colour shades. But you can also order custom colour variants from us from a corresponding batch size.
According to the state of the art, indicated in IVD instruction sheet no. 12, motion-compensating sealants are not painted over fully for technical reasons. If this is demanded or necessary nevertheless in exceptional cases, sealants can be painted over / coated over if they have an acrylate, polyurethane or hybrid basis. The compatibility between the coating and the product must be checked by the processor beforehand. If the product is painted over completely in exceptional cases following the compatibility check, the coating must also be able to follow the elastic movement of the sealant. Otherwise cracks may form in the coating or visual impairments may result.
At low temperatures, there is a risk of condensation forming a thin, invisible layer of ice or water on the substrates. This separating layer prevents optimal adhesion of the sealants to the substrate.
Primers are bonding agents, which improve the sealant adhesion on porous or problematic substrate. The primer leaves a film or bonding residue behind on the subsurface on which the sealant can form a better bond. Substrates must be dry and clean when priming. Primer must be applied sparingly to non-absorbent substrates and generously to absorbent substrates. Please also observe the respective technical data sheet and the primer table.
Our application consultation is available Monday to Thursday from 8:00 a.m. to 4:00 p.m. and Friday from 8:00 a.m. to 2:00 p.m. and will be happy to receive your request.
