Acrylic adhesives are part of the structural adhesive family, making them a great multi-purpose and versatile bonding choice. They can bond a wide range of substrates and are available in two-part catalyst cure or one-part UV and heat cure formulations.

Read on to find out 6 common uses of acrylic adhesives and the reasons why they work so well in each application.

1. Sign Making 

Acrylic adhesives can be used to bond thinner materials, such as prepared or unprepared metals and engineered plastics, which traditional mechanical fastening methods could not. This gives sign makers much more design freedom as well as reducing manufacturing costs. The adhesives clear formulation and ability to gap fill means that it is virtually undetectable on translucent substrates, such as plastic point of display signs. The weather resistance and anti-corrosion properties of acrylic adhesives allow them to also be used to create signs designed for outdoor display purposes.

2. Sporting Goods

The manufacturing of sporting goods such as golf clubs or goal frames involves the bonding of robust materials such as aluminium and steel. These bonds are placed under extreme stress and rigorous wear and tear when in use. Acrylic adhesives provide the joints with high levels of impact resistance which ensures they are long-lasting and durable. They can bond the robust materials with ease, as well as joining any smaller, complex parts to the goods without any restrictions. Furthermore, there is no additional finishing work required when using acrylic adhesives meaning a faster turnaround and a polished aesthetic.

3. Automotive Manufacturing

The possibilities and uses for structural adhesives within the automotive sector are truly extensive. Acrylic adhesives are being implemented in this area as a replacement for traditional bonding methods such as welts, rivets and brazing. Acrylic adhesives work exceptionally well in the bonding of aluminium, steel and composite materials. They are used for the bonding of exterior vehicle components such as door panels and frame work. These components are subject to high impact and stress daily, however acrylic adhesives provide a durable and flexible join which can withstand these pressures. They also improve aesthetics and reduce manufacturing costs making them a highly popular bonding method with vehicle manufacturers.

Instant adhesives, otherwise known as cyanoacrylates or “super glues” are the most commonly used adhesive in the industry. Instant adhesives are considered to be general purpose as they suit a wide range of diverse applications and adhere to a host of different substrates. This adhesive type cures when exposed to the moisture in the air, and provide a durable, high strength bond.

In this post, we’ve highlighted 8 reasons why you should make instant adhesives your chosen bonding method.

1. Versatile Bonding 

Instant adhesives provide excellent adhesion to a wide variety of substrates, from metal and wood to porcelain and ceramics. This means that instant adhesives can be used not just for industry use, but also to repair everyday items such as those found around the home. With huge advancements in the market, newer variations of instant glues have been produced to work with traditionally difficult to bond plastics such as polypropylene.

 

We Recommend: Henkel Loctite 401 Instant Adhesive

2. Economical Choice

The bonding of smaller or more obscure items can be made easy with the use of instant adhesives. Only a very small amount of glue is required to achieve a high level of polymerisation and in-turn, an extremely high strength bond. This makes cyanoacrylate an economical and cost-effective adhesive choice as the best bonds are produced using a minimal amount of adhesive.

We Recommend: Henkel Loctite 414 Instant Adhesive

3. Rapid Cure Times

Cure times vary between different compositions of instant adhesives, typically ranging from just a few seconds up to few minutes. This super-fast cure makes them highly effective in demanding applications. As very little adhesive is required to join the substrates, the adhesive achieves handling strength in just seconds. Instant adhesives are available in a variety of different viscosities and cure speeds meaning they suit a vast array of applications.

We recommend: Henkel Loctite 4062 Low Viscosity, Fast Cure Adhesive

4. Safe for Medical Use

Instant adhesives adhere well to other substrates too, most uniquely human skin. The medical industry uses this versatility to their advantage and have implemented the medical-grade glue as a quick and effective way of temporarily sealing wounds. Furthermore, instant glues are frequently used in the production of disposable medical devices where quick production times and reduced manufacturing costs are critical.

5. Easy to Implement

There is no need for mixing or measuring instant adhesives as they are supplied as a one part, ready to use material. This makes them ideal for high speed production processes as they require no clamps or additional equipment prior to use, saving both space and money.

 We recommend: Permabond 102

6. Aesthetically Pleasing

As instant adhesives require a very minimal amount to be deposited onto the substrate for a high strength bond to form, there is little risk of mess or overspill if used correctly. The adhesive cures clear which leaves minimal to no trace between substrates. This makes cyanoacrylates particularly well suited for more intricate applications.

We recommend: Henkel Loctite 416 Adhesive

7. Suitable for Porous Surfaces

Whilst low viscosity instant adhesives have a runny, liquid consistency, many are manufactured with a very high, gel-like viscosity which can be used for gap filling. Thanks to their thicker formulation, cyanoacrylate gels prevent adhesive flow even on vertical surfaces and can be used to bond porous substrates such as leather or paper.

We recommend: Henkel Loctite 3090 Instant Adhesive Gel 

 

 

8. Flexible Bonds

Flexible instant adhesives are available to be used in the production of difficult to bond materials such as rubbers and plastics which often compress the finished joint. Flexible instant adhesives produce a flexible bond line as they are formulated with rubber additives, allowing movement in the joint and between the substrates without any damage.
