BETOCHEM 205 a two-component primer free of solvents, based on epoxy.
ETOCHEM 205 is easy to process, has good adhesive strength and can be finished wet-in-wet with mortars based on epoxy resin.
BETOCHEM 205 has good penetrative qualities on porous grounds.

This material can also be supplied as BETOCHEM 205 VO, specially for surfaces with max humidity of 10 %

Quality control

During manufacturing only raw materials of high quality are used which amply meet the strictest requirements. During the production process as well as during the final stages these materials are extensively tested for quality in our own laboratory.

Application areas
  • BETOCHEM 205 Adhesive can be applied as adhesive layer to concrete and other stone-like grounds, specifically as a primer for Betec cement based products
  • As impregnation of concrete and brick-work to render them resistant to wear, water and chemicals
  • When applied as adhesive primer, BETOCHEM 205 adhesive should be processed in combination with BETEC mortars WET-IN-WET; if the BETEC products cannot be applied within processing time, then spray in the primer within processing time and apply the BETEC products after approximately 18 hours.
