Low odour adhesives for bonding plastics and metals

Structural acrylic adhesives are popular because they form high strength bonds; most of them cure rapidly. Because of this, structural acrylic adhesives are ideal for structural bonding and lend themselves to high speed production processes where it is impractical to clamp the part and cure the adhesive overnight or in an oven.

However, there is a well-known drawback… They can be pretty smelly! Some people quite like the smell but for production line operatives that have to use the adhesive day in and day out, it can be unpleasant and uncomfortable.  Good air flow and extraction is essential but not all employers provide this due to cost of installation or the space required.  There is some good news though! Permabond has launched its new low odour structural acrylic adhesives. These combine the high strength performance associated with structural acrylic adhesives with the fast cure and rapid strength development properties revered by adhesive users.

Permabond TA452

This low-odor structural acrylic combines resin and hardener in a 1:1 mix ratio to provide handling time in 6-9 minutes. It is particularly suited to metal bonding applications. It’s low shrinkage characteristics help prevent show-through on thin metallic skins which can sometimes be a problem with MMA-based structural adhesives.

Permabond TA4522

With a slightly longer handling time of 10-15 minutes, this low-odour acrylic is especially good for bonding plastics as well as metal substrate materials.

These products offer high shear and peel strength, good impact and vibration resistance, and are ideal for bonding dissimilar surfaces where differential thermal expansion and contraction could be an issue. They are ideal for bonding composite materials and are a popular choice for materials such as Alucobond – especially for applications which require a good aesthetic appearance with no visible fasteners or drill holes. Shop fitters, sign makers, and architects may find these adhesives good to work with as they don’t smell bad, they’re easy to use, and they offer good bonding performance.
