Questions and answers about our OTTOSEAL® sealants

What sealants can be completely painted over?

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.

Why should you not apply sealants at te+C48:C49mperatures below + 5°C?

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.

  • Single-component hybrid, PU and silicone products require ambient humidity to harden which is virtually non-existent at low temperatures below + 5°C.
  • Water-based sealants such as dispersion acrylates are sensitive to frost when fresh and must not be processed at temperatures below + 5°C.

How does a primer affect the interplay between the sealant and the subsurface?

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.
