DeWALT advises on the safe selection of adhesive anchors

When carrying out a safety-critical installation, a construction fixings failure can have potentially fatal consequences. To help installers make safe decisions, DeWALT has outlined the differences between Pure Epoxy, Vinylester and the cheaper Polyester anchors.

Polyester adhesive anchors are often used as a universal fixing solution as, in comparison to Pure Epoxy and Vinylesters, they are cheap and readily available.

However, this type of chemical anchor can suffer from long term shrinkage, making them more suitable for non-structural or temporary fixing in dry conditions than long term solutions.

DeWALT believes that it is important to understand the differences between various resin-bonded anchors to make a safe decision.

Using its recently launched range of fixing systems, the company demonstrates how individual fixings are designed with unique properties to suit different applications.

Pure Epoxy adhesive anchors (PURE 110-PRO and PURE 150-PRO)

DeWALT’s Pure Epoxy Anchors have been approved for use in cracked and uncracked concrete. Suitable for diamond drilled holes, the anchors can be used in water filled holes and in poor or wet site conditions.

Dubbed as a ‘premiership’ product, the anchors offer high loading and thermal properties, as well as resistance to chemicals.

With a 24-month shelf life and almost no shrinkage, they are suitable for long tern use.

Vinylester adhesive anchors (AC100-PRO and AC100 NORDIC)

Alike its Pure Epoxy Anchors, DeWALT’s Vinylester Anchors have been approved to ETA-Option 1.

Designed to offer fast curing times and high adhesive resistance in alkaline conditions, the anchors are suitable for use in wet conditions and water filled holes.

They also offer high mechanical loading and thermal properties in an assortment of base materials.

Polyester adhesive anchors (PV45-PRO and PV50-PRO)

DeWALT has developed its Polyester Anchors to offer a cost-effective solution for low load fixing into masonry or dry hollow blocks.

Although these anchors are not recommended for safety-critical applications, they are quick curing and suitable for a wide range of base materials. They also hold ETA-Option 7 approval for M8-M24 rods.
