XCHEM PRO Chemical Anchor Comparison Chart: Epoxy, Hybrid, Vinylester and Polyester
Hobson's A1 wall chart comparing the four XCHEM PRO chemical anchor resins: E701 epoxy, H501 hybrid, V401 vinylester and P201 polyester. It shows each resin's features, working and curing times by temperature, which base materials it suits, a load comparison for class 5.8 threaded studs and the matching mixer nozzles, extension tubes and guns.
What this covers
- Resin comparison
- Working and curing times

Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- E701 epoxy is the highest performance resin in concrete and the slowest curing; H501 hybrid is high performance in concrete; V401 vinylester is for concrete and masonry; P201 polyester is the cost effective, general purpose option.
- E701, H501 and V401 are marked for cracked and non-cracked concrete, fire resistance and rebar, with seismic C1 and C2 for E701 and H501, and seismic C2 for V401 in M12 and M16 only. P201 has none of these ratings.
- At 20°C the maximum working time is 25 minutes for E701, 6 minutes for H501 and 5 minutes for V401 and P201. Minimum curing time in dry holes at 20°C: 18 hours, 45 minutes, 30 minutes and 30 minutes. Wet holes take about twice as long.
- Base materials: H501 is ticked for all seven listed, including aerated concrete and calcium silicate; V401 for everything except calcium silicate; P201 for concrete, stone and solid and hollow masonry; E701 for concrete and natural stone only.
- Ultimate load (kN), not a working load: class 5.8 stud, single anchor, dry hammer drilled hole, away from edges, 32 MPa non-cracked concrete, short-term temperature up to 40°C. M12 at 110mm: E701 28.0, H501 26.5, V401 22.0, P201 11.0. M16 at 125mm: 52.0, 40.1, 31.6, 13.4.
- The figures come from independent European approvals with calculations to AS 5216, and the chart is labelled AS 5216 and NCC compliant.
Who it helps: Builders and engineers choosing between epoxy, hybrid, vinylester and polyester chemical anchors.
