A Beginner’s Guide to Epoxy Adhesives

Epoxy adhesives are made by mixing two components together: the resin and the hardener. When the resin is mixed, it begins to cure. It is this chemical reaction that determines what type of properties the epoxy will have. The exothermic reaction links the polymers, and this will affect the strength and rigidity of the bond and determine what practical applications it can be used for. A very common practical application this can be used for certain types of  plumbing tasks , a Cheltenham plumber company, like https://actdirect.co.uk/services/emergency-plumber-cheltenham/  could use this method.

Thermal conditions can also alter the structure of the glue and, by extension, its potential uses. Monitoring heat can change the mechanical strength when considering the resin and hardener. Adapting the thermal conditions can expand the range of uses for epoxies. This has been taken into consideration to manufacture a range of epoxies to suit different applications.

Here is a look at the two main types of epoxies available.

One-component system

These epoxy adhesives are cured at temperatures of between 250 and 300 degrees Fahrenheit. These conditions ensure they are a product of enormous strength with excellent resistance to environmental factors and chemical resistance. It is these qualities that make them an exceptional metal bonding adhesive. They are so suitable for use with metal that they are replacing welding and riveting in manufacturing. They are designed to be activated under conditions of moderate heat. This allows for improved efficiency and helps avoid air getting trapped in the bond.

Two-component system

A two-component epoxy can be cured at room temperature, or you can apply some heat to speed up the curing process. Adding heat will also improve the rigidity of the glue and increase its performance. They are suitable for bonding most surfaces, and they provide excellent stability due to their performance under sustained conditions of extreme weight and force. Like the one-component system, they are resistant to chemicals and environmental factors. They can be used for sealing, bonding, coating and encapsulating objects such as yachts.

Uses for Epoxies

They can be used for household applications such as sealing baths and toilets, and they can be used for household repairs.

Two-component epoxies are currently being used across a range of industries thanks to their superior properties. They are used in aerospace, electronics and in the production of medical equipment. Their adaptability ensures their future use in many industrial applications.
