Parex Epoxy Adhesive 305
Parex Epoxy Adhesive 305 is an epoxy resin-based compound suitable for placing using hand tools or by means of a hand held applicator gun. The three-pack product consists of resin in a mixing tub, a bottle of hardener and a bag of specially graded fillers.
Parex Epoxy Adhesive 305 is used for jointing concrete, brickwork, masonry, elastomeric bearings, timber, ceramic tiles, aluminium and steel. Typical uses include bonding of precast units, placing of elastomeric bridge bearings, bonding horizontal fixings and setting frames in precast concrete units.
The mixed material may be used as an epoxy resin anchor for fixings placed in horizontal holes and “gunned” into narrow gaps such as setting security doors or window frames.
For site use only hand mixing is required, the applied product is self priming giving excellent adhesion to most construction materials. Formed joints are volume stable producing stress free adhesion.
The cured material is resistant to sea water, most chemicals including acids, alkalis, petroleum products and is freeze-thaw stable.
Uses Include:
- Bonding of precast units.
- Placing of elastomeric bridge bearings.
- Bonding horizontal fixings.
- Setting frames in precast concrete units.

Instructions For Use
Preparation
Remove laitance and all loose material including dust, oil and grease to achieve a sound substrate. Steel surfaces should be free of mill scale and rust. Aluminium surfaces should be oxide free and abraded. Wood surfaces should be dry and resin free. Working surfaces should be in a surface dry condition. For use with stainless steel surface preparation to SA21⁄2 is required.
Mixing
The mixing of Parex Epoxy Adhesive 305 should be carried out with full packs only. Pour all of the hardener into resin base container which has enough volume to act as the mixing vessel. Mix by hand, using suitable hand tools, for 1-2 minutes until homogeneous. Slowly add the filler continuing to stir and until the mix is again homogeneous.
Placing
Place the mixed material using a clean trowel or other suitable hand tool. If gunning the product into place, fill a 1 litre Tecgrip cartridge and insert the end cap. Use a Tecgrip Gun to inject the Epoxy Adhesive 305 into the working gaps. Do not disturb the filled section until the Epoxy Adhesive 305 has hardened. Tools and mixing equipment should be cleaned with Solvent before the Parex Epoxy Adhesive 305 has started to harden. Place in gap widths between 3mm and 15mm at temperatures between 5°C and 45°C. For temperatures outside this range contact The Technical Service Department.
