Sika stocks a range of chemical resin anchoring adhesives that are well-suited for high load applications.

Anchoring adhesives have distinct advantages over mechanical anchors because they provide excellent corrosion protection, are cost-effective, and have a keying effect and hold even, in porous substances. They also have full resin embedding of the anchor and have highly crosslinked duromer.

Chemical anchors are flexible in that they cater to anchors with close spacing, close edge distances and they provide anchoring in wide range of scenarios.

Our range of anchoring adhesives includes:
