Adhesives

Repco offers a comprehensive range of automotive adhesives designed to tackle a variety of repair tasks with ease. From the versatile epoxy putty that fills gaps and bonds metal, to Loctite super glue and Loctite 401 for quick, strong fixes, there is a product for nearly every need. For sealing and flexible bonding, Sikaflex 221 and silicone adhesive provide durable solutions that withstand heat and vibration. These adhesives are suitable for both minor touch-ups and more demanding repairs, giving you confidence in your vehicle maintenance. Repco’s range balances performance and practicality, helping both beginners and experienced mechanics find the right adhesive without confusion or guesswork.

What are the 6 general types of adhesives?

There are six general types of adhesives commonly used in automotive and general repair: epoxy adhesives, cyanoacrylate adhesives (super glue), polyurethane adhesives, silicone adhesives, solvent-based adhesives, and anaerobic adhesives. Epoxy adhesives, such as epoxy putty, provide strong, durable bonds and are ideal for metal, plastic, and composite repairs. Cyanoacrylate adhesives, including Loctite super glue and Loctite 401, set quickly and bond well to small parts and plastics. Polyurethane adhesives like urethane glue offer flexibility and water resistance, making them suitable for sealing and bonding in areas exposed to vibration or moisture. Silicone adhesives, such as Sikaflex 221 and black sikaflex, provide excellent sealing and flexibility, often used for gaskets and weatherproofing. Solvent-based adhesives, like Selleys quick grip and Selleys kwik grip, dissolve surfaces to create a strong bond on plastics and rubbers. Anaerobic adhesives cure in the absence of air and are commonly used for threadlocking and sealing metal fasteners.

What is the best auto adhesive?

The best auto adhesive depends on the specific application and materials involved. For structural repairs on plastic parts, JB Weld plastic bonder or JB plastic weld provide a strong, heat-resistant bond suitable for bumpers, trims, and housings. Epoxy putty is excellent for filling gaps and repairing metal or plastic components where a durable, machinable bond is needed. For quick fixes or small parts, Loctite super glue or Loctite 401 offers fast curing and strong adhesion on plastics and rubber. When flexibility and sealing are required, urethane glue or silicone adhesive products like Sikaflex 221 and black sikaflex are preferred for weather seals, windscreen bonding, or trim attachments. For general plastic repairs, Selleys knead it aqua and Selleys quick grip provide user-friendly options with good adhesion and water resistance. Choosing the right adhesive involves considering strength, flexibility, curing time, and exposure to heat or moisture.

Is super glue stronger than JB Weld?

Super glue, such as Loctite super glue or Loctite 401, is known for its fast curing time and strong initial bond, especially on small surfaces and non-porous materials. However, JB Weld products, including JB Weld plastic and JB Weld extreme heat, generally provide a stronger and more durable bond, particularly for heavy-duty or structural repairs. JB Weld adhesives are epoxy-based and cure to a hard, heat-resistant finish that withstands vibration, impact, and high temperatures better than typical cyanoacrylate adhesives. For automotive repairs involving metal parts, engine components, or plastic parts exposed to heat and stress, JB Weld is usually the preferred choice. Super glue is better suited for quick fixes or bonding small parts that do not endure significant mechanical stress.

How does epoxy putty work?

Epoxy putty is a two-part adhesive that, when mixed, initiates a chemical reaction causing it to harden into a solid, durable material. It is mouldable before curing, allowing it to fill gaps, cracks, or holes in metal, plastic, or composite surfaces. In automotive use, epoxy putty is ideal for repairing engine blocks, radiators, plastic housings, and body panels. It bonds well to most surfaces, resists heat and chemicals, and can be sanded or drilled once cured. Products like Selleys knead it aqua and JB plastic weld offer variations of epoxy putty suited for water resistance or high-temperature applications. Using epoxy putty involves cleaning the repair area, mixing the components thoroughly, applying the putty to the damaged section, and allowing sufficient curing time as per manufacturer instructions. This provides a long-lasting repair that restores structural integrity.

What is Loctite 401 used for?

Loctite 401 is a fast-curing cyanoacrylate adhesive designed for bonding a wide range of materials including plastics, rubbers, and metals. In automotive applications, it is commonly used for quick repairs on trim, badges, small plastic parts, and rubber seals. Its ability to bond dissimilar materials quickly makes it useful for emergency fixes or assembly tasks where speed and strength are required. Loctite 401 performs well on low surface energy plastics that are typically difficult to bond with standard adhesives. It cures rapidly at room temperature and provides a strong, durable bond resistant to vibration and moderate environmental exposure. For best results, surfaces should be clean and dry before application. Loctite glue products like this are a practical choice for both professional workshops and DIY enthusiasts needing reliable adhesion without lengthy curing times.
