KhTA EP V4 epoxy chemical anchor — 450 ml cartridge, 2:1 ratio

Chemical anchors

According to the manufacturer, KhTA EP V4 differs from V3 in container volume and component ratio: this version has a 450 ml cartridge and a 2:1 ratio. The amine-cured epoxy compound bonds M8–M30 studs and rebar into cracked and non-cracked B25–B60 concrete, stone and brick; it is not intended for timber. Installation is possible at temperatures not below 0 °C (at 0 °C strength gain takes 48 h), and the finished connection operates from −40 to +40 °C; the anchor holds technical certificate No. 7471-26 of the Ministry of Construction of Russia.

Packagingtwo-component cartridge 450 ml
Application methodfixing of metal elements (threaded stud, rebar) in concrete, stone, brick (not for timber); concrete B25–B60, cracked and non-cracked, post-installed rebar starters permitted; studs M8–M30: d0 10 / 12 / 14 / 18 / 22 / 27 / 30 / 32 mm, hef 60–160 (M8) … 145–600 mm (M30), tightening torque 10…300 N·m, hmin = hef + 30 ≥ 100 mm (or hef + 2d0), Smin = 6 hef, Cmin = 3 hef; condition the cartridge for at least 24 h at +15…+30 °C before work; clean the hole with a brush and blow it out; squeeze the first 5–10 cm of compound onto a test surface until the colour is uniform; fill the hole to 2/3, insert the element to the bottom while turning it 2–3 times, the position can be adjusted until curing; apply load after strength gain; cleaning — Nefras, turpentine
Application temperaturenot below 0 °C; curing at 0…+40 °C
Curingcuring time / strength-gain time by substrate temperature: +31…+40 °C — 10 min / 2 h; +21…+30 °C — 15 min / 4 h; +11…+20 °C — 30 min / 6 h; +1…+10 °C — 2 h / 24 h; 0 °C — 6 h / 48 h; in a damp substrate the full strength-gain time increases 2-fold
Key propertieshomogeneous non-sag paste of beige colour; characteristic pull-out loads Rn in non-cracked B25 concrete (stud 5.8, hef 80 / 90 / 110 / 125 / 170 / 210 / 240 / 280 mm): 9.3 / 10.8 / 25.3 / 31.2 / 55.2 / 75.5 / 112.4 / 156.5 kN (M8 / M10 / M12 / M16 / M20 / M24 / M27 / M30); cracked 4.4 / 6.2 / 9.1 / 14.3 / 25.0 / 34.7 / 42.3 / 52.0 kN; shear Vn 9.2 / 14.5 / 21.1 / 39.3 / 61.3 / 88.3 / 114.8 / 140.3 kN; service temperature of the finished connection −40…+40 °C
Shelf life12 months from the date of manufacture, unopened; storage and transport −25…+40 °C; opened cartridge with the mixer left on — no more than 2 weeks, replace the mixer before reuse
