A derivative of petroleum, epoxy forms a strong and lasting bond. Epoxy adhesives are resistant to chemicals, moisture, and corrosion.
2.Cyanoacrylate adhesives
An extremely strong and fast-acting adhesive, this forms a permanent bond in just 30 seconds. These are used regularly in engineering and manufacturing.
3. Hot glue adhesives
These adhesives come in plastic tubes/sticks. A hot melt gun melts the stick – turning it into liquid and allowing it to be applied as needed. As it cools, it solidifies and creates the bond.
4. Polyvinyl acetate adhesive
Commonly-known as PVA, craft glue, or wood glue, this synthetic adhesive is highly versatile, non-toxic, and forms a strong bond.
5. Pressure-sensitive adhesives
Traditionally made from plastics, these do not need any activation other than pressure. They can be found on various tapes as well as on sticky-notes and some stamps.
6. Acrylic adhesives
These can be used on a wide range of materials including acrylic, glass, wood, and plaster. They are UV-resistant, non-toxic, and offer impressive bond strength.
If you’re looking for metal bonding adhesive or other niche adhesives, there are several companies specialising in adhesives, such as CT1, who offer unique and innovative products.
7. Contact adhesives
Sometimes known as grab adhesives or dry-film glues, these automatically grip and bond when applied. They are often used with carpets, cardboard, and wooden surfaces.
8. Silicone adhesives
Known for their strength and versatility, silicone adhesives are easy to use, flexible, and resistant to moisture. They are used widely in the electronics, construction, aeronautics, and engineering sectors.
9. Polyurethane adhesives
These can be used on porous and non-porous materials. They are a popular choice for wood due to their high strength, elasticity, and non-toxic nature.
10. Anaerobic adhesives
Anaerobic adhesives require an absence of air as well as metallic ions in order to harden. Approximate curing time is 24 hours. These are often used for joining metal, and typical applications include sealing threads and gasketing.
