Over recent years Tecfi SpA has heavily invested in developing its range of chemical anchors, strongly believing in the advantage of reducing edge distances and spacing, without pre-stressing the base material.
As a result, Tecfi was one of the first companies to achieve the C2 performance category on a styrene-free dual component pure epoxy chemical anchor – for use with threaded rods from M16 to M24 – according to the Annex E of the ETAG 001. SWE01 epoxy resin is also ETA-CE certified in Option 1 for cracked concrete – for use with threaded rods from M12 to M24 – and Option 7 for non-cracked concrete – for use with threaded rods from M8 to M30 – according to ETAG 001 – Part 1 and 5. In addition, SWE01 achieved a Technical Report (TR023) for post-installed rebar connections from diameters 8mm up to 32mm.
Furthermore, Tecfi has recently achieved the C2 performance category on the DGE02 styrene-free dual component vinylester resin for use with threaded rods from M12 to M16 and C1 performance category for use with threaded rods from M12 to M20. In addition, DGE02 got an ETA-CE for use with rebars from diameters 8mm to 32mm with exposure under fire and in seismic areas.
These upgrades have been welcomed in the market with a very big enthusiasm, as customers can now use, in seismic areas, a vinylester chemical anchor with standard and easy to find threaded rods or rebars, and not just with very special and expensive anchor rods.
These last achievements consolidate the very high status of the DGE02, already certified in ETA-CE Option 1 for use in cracked and non-cracked concrete with threaded rods from M10 to M20 and ETA-CE Option 7 for use in non-cracked concrete with threaded rods from M8 to M30.
Tecfi has also developed two varieties of vinylester resin, which are suitable for extreme climates that come with the same high grade certifications: DGE12, suitable for low temperatures, guaranteeing a fast curing; and DGE22, suitable for high temperatures and guaranteeing slow curing.
DGE02, DGE12 and DGE22 can also be used in wet concrete and flooded holes, except for rebars installation and in seawater. DGE02 is available in 300ml and 400ml cartridges, while DGE12 and DGE22 are available in 400ml cartridges.
In order to enlarge its range of vinylester bonded anchors, Tecfi is now launching the new DGE03, a styrene-free dual component epoxy acrylate vinylester resin, that has achieved the ETA-CE Option 7 for use in non-cracked concrete with threaded rods from M8 to M16 and rebars from diameters 8mm – 16mm.
Moreover in 2017, Tecfi introduced EHE01, a dual component vinylester resin in glass capsule, which achieved the ETA-CE Option 7 certification for use in non-cracked concrete, with threaded rods from M8 to M30. EHE01, which can also be installed in wet concrete, avoids any waste on the jobsite thanks to the pre-sized capsule.
Tecfi has also invested huge resources in its polyester resins. In fact, in 2017 it launched a new dual component polyester resin, under range code DGE00, available in 300ml and 400ml cartridges. DGE00 achieved the ETA-CE certification for use in solid masonry (use category b) and hollow or perforated masonry (use category c) with threaded rods from M8 to M12, ensuring a very good compromise between quality and price.
At the same time, Tecfi decided to raise the level of its DGE01, the styrene-free dual component polyester resin, which is now an extremely flexible product – suitable for a very wide range of base materials. In fact, it got the ETA-CE Option 7 certification for use in non-cracked concrete with threaded rods from M8 to M16, according to ETAG 001 – Part 1 and 5. It came in addition to the recognition that DGE01 had achieved several years earlier, the ETA-CE certification for use in solid masonry (use category b) and hollow or perforated masonry (use category c) with threaded rods from M8 to M12. DGE01 is available in 300ml and 400ml cartridges.
Finally, Tecfi also offers a very wide range of studs for chemical anchors with nut and washer: Slotted dog point steel bars in 8.8 grade (range code DAT02), 45° sliced steel studs in 5.8 grade (range code LN01), flat ended steel rods in 5.8 grade (range code DA02), studs with hex shank and double 45° cut in steel (5.8 grade, range code DAF02) and A4-70/AISI 316 stainless steel (range code DAF72).
