Speeding Up the Curing Time through Adhesive Accelerator


Industrial adhesives have become an option for assembly applications. Traditionally, metal parts were bonded through welding, rivets or mechanical fasteners but reliable bonding cannot be achieved with dissimilar substrates. Adhesives offer numerous advantages from cost savings to enhanced speed of curing time. When adhesive accelerator is pre-applied or post-applied to an assembly, it can increase cure rates of instant adhesives.

Benefits of using adhesives in the assembly process

Contrary to the belief of some product manufacturers, industrial adhesives are reliable and strong enough to join metal parts. Developments in the technology of adhesives have improved quality and it has become easier to determine whether the right amount of adhesive has been placed on the joint to create a very strong bond. The introduction of adhesive accelerator has also speeded up curing time when the application makes use of cyanoacrylates. Adhesive accelerator is one of the tools offered by adhesive manufacturers to provide the right solution in the fabrication of metal products.

One of the advantages of using adhesives for bonding is the even distribution of stress instead of being centralized on the weld joint or at the point of mechanical attachment. Adhesives are spread evenly across the entire bond so that it can provide a tight seal that remains unaffected by harsh conditions in the environment.

The use of adhesives has aesthetic advantages. For instance, welds can be unsightly including protruding screw heads and bolts. They can seriously affect the aesthetics of a product particularly when there are surface markings that have not been successfully covered by paint or powder coating. A smooth bonded surface can easily be provided through the use of industrial adhesives. When applied, the adhesives remain invisible in spite of being able to achieve a durable and strong bond.

Bonding of dissimilar substrates can be efficiently achieved through industrial adhesives. For example, metal parts and plastic can be joined together even if they have different coefficients of thermal expansion. This means that when materials are subjected to heat, they expand at different rates. Industrial adhesives also allow bonding of coated, galvanized and painted metals without seriously affecting the way the surface has been finished. This is not possible with welding or when you drill holes to make way for mechanical fasteners.

The expansion and development of available industrial adhesives have increased the options of product manufacturers. Today, there is a wide range of industrial adhesives that include epoxies, cyanoacrylates, polyurethanes and adhesive accelerator. Adhesives have become a cost effective option for the assembly of finished products. There are various chemistries available from pastes, liquids and films with some measure of controlled thickness. Many of these industrial adhesives do not produce out-gassing which significantly prevents voids when cured.

There are also various methods of application depending on the chemistry of the adhesive. It can either be spread manually or it can be dispensed using a nozzle. However, to achieve the best bonding results, it is important to provide adequate curing conditions after the parts has been assembled properly.
