In recent years Tecfi SpA has invested a lot in developing its range of chemical anchors, strongly believing in the advantage of reducing edge distances and spacing, without pre-stressing the base material.
In 2017 Tecfi launched a new dual component polyester resin, under the 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,
which the company points out ensures 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 recently received the ETA-CE Option 7 certification for use in non-cracked concrete with threaded rods from M8 to M16, according to ETAG001 – part 1 and 5. It came in addition to the recognition that DGE01 had achieved several years earlier, which was 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.
In 2017 Tecfi also introduced EHE01, the new dual component vinylester resin in glass capsule, which achieved ETA-CE Option 7 certification for use in non-cracked concrete, with threaded rods from M8 to M30, according to ETAG001 – part 1 and 5. EHE01, which can also be installed in wet concrete, avoids any waste on the jobsite thanks to the pre-sized capsule.
EHE01 enlarges the range of vinylester bonded anchors already included in the Tecfi programme.
DGE02 styrene-free dual component vinylester resin achieved the ETA-CE Option 1 certification for use in cracked and non-cracked concrete with threaded rods from M10 to M20 and the ETA-CE Option 7 certification for use in non-cracked concrete with threaded rods from M8 to M24, according to ETAG001 – part 1 and 5. Moreover DGE02 is ETA-CE certified for use with rebars from diameter 8mm to 32mm, according to ETAG001 – part 1 and 5 – TR023. DGE02 is available in 300ml and 400ml cartridges.
Tecfi also developed two varieties of DGE vinylester resin, which are suitable for extreme climates: DGE12, suitable for low temperatures, guarantees a fast curing; DGE22, suitable for high temperatures, guarantees a slow curing. DGE12 and DGE22 are both available in 400ml cartridges.
DGE02, DGE12 and DGE22 can be also used in wet concrete and flooded holes, except for rebars installation and when used in seawater.
Tecfi was also one of the first companies to achieve the C2 performance category on a styrene-free dual component pure epoxy chemical anchor (use with threaded rods from M16 to M24), according to the Annex E of the ETAG001. SWE01 epoxy resin is also ETA-CE Certified in Option 1 for cracked concrete (use with threaded rods from M12 to M24) and Option 7 for non-cracked concrete (use with threaded rods from M8 to M30), according to ETAG001 – part 1 and 5. In addition, SWE01 achieved a Technical Report (TR023) for post-installed rebar connections from diameter 8mm up to 32mm.
Tecfi’s whole range of chemical anchors use a low VOC/A+ classified formulation that enables the use of the resins also in indoor environments.
Finally, Tecfi also offers a very wide range of studs for chemical anchors with nut and washer, including: 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).
In addition, a wide range of professional hand guns, pumps for hole cleaning and plastic and metallic sleeves enrich Tecfi’s programme. All Tecfi chemical mortars are included in the TADS – Tecfi Anchor Design Software.
