Sika® Primer-115 – System primer for Sikaflex® TS Plus (1 litre)

Sika® Primer-115 is a high-quality, one-component, transparent reactive primer for improving the adhesion of Sikaflex® sealants on porous and absorbent substrates. The primer was developed specifically as the system primer for Sikaflex® TS Plus and is mandatory for applications on concrete in accordance with building-authority approval Z-74.62-151.

Thanks to its special formulation, Sika Primer-115 ensures reliable adhesion promotion between sealant and substrate. It is particularly suitable for mineral and highly absorbent building materials such as concrete or freshly cut asphalt, and enables permanently secure sealing in the construction and industrial sectors.

Thanks to the short flash-off time of at least 30 minutes, processing can proceed efficiently. The maximum further-processing time is up to 8 hours, ensuring sufficient flexibility during application.
