Chemistry, Adhesives

About Chemistry & Adhesives

Chemistry and adhesive products are the chemical bonding and anchoring agents used alongside mechanical fastenings in architectural hardware installations.

Chemical anchor-mass bonds a threaded rod or stud into a drilled hole through a curing resin, providing high pull-out resistance in substrates where mechanical expansion anchors are insufficient — such as hollow masonry, aerated concrete and close-to-edge fixings.

Anaerobic glue permanently locks stainless-steel threaded connections and bonds close-fitting metal parts by curing in the absence of air.

Strofix supplies three products in this category: a 50 mL anaerobic glue formulated for stainless-steel bonding, a 300 mL standard chemical anchor-mass (Essve), and a 300 mL winter-grade chemical anchor-mass (Essve) for installations at low ambient temperatures.

The correct product depends on whether the task is substrate anchoring or metal-to-metal bonding, and whether installation takes place in standard or cold-weather conditions.

How to choose a chemistry or adhesive product

1. Task: substrate anchoring or metal-to-metal bonding

This is the first decision. If you are fixing a threaded rod, stud or anchor into a drilled hole in concrete, masonry or another mineral substrate, choose a chemical anchor-mass.

If you are locking a threaded connection between two stainless-steel components — for example, securing a cover cap, locking a set screw or bonding a handrail connector — choose anaerobic glue.

2. Installation temperature: standard or winter

The standard chemical anchor-mass (Essve, 300 mL) cures at normal ambient temperatures.

The winter-grade chemical anchor-mass (Essve, 300 mL) is formulated to cure reliably at low temperatures, typically down to −5 °C or below depending on the manufacturer's specification.

Choose the winter variant when the installation takes place in cold weather or in unheated spaces during the colder months.

3. Volume

Chemical anchor-mass is supplied in 300 mL cartridges, which is sufficient for multiple anchor points in a typical installation.

Anaerobic glue is supplied in a 50 mL bottle — a small quantity goes a long way, as only a thin film between close-fitting surfaces is needed for a full-strength bond.
