Sika Primer 507 250ml black

Sika Primer-507 has been specially developed for priming surfaces of materials to be bonded before applying Sika's elastic adhesives/sealants. This primer can produce excellent adhesion results without prior separate activation treatment on a variety of materials. The surface of Sika Primer-507 is visible as fluorescent under long-wave UV light for a limited time. This property is used to ensure the quality of the priming work in production line bonding.
