Industrial adhesives are vital components in modern manufacturing and construction processes due to their versatility and strong bonding properties. They have a wide range of applications and come in various forms, catering to diverse needs. Understanding and mastering their application techniques is essential for achieving optimal results. From super glues to silicone sealants, here are the most common types of industrial adhesives, their uses, and some tips for their application.
What is Adhesive?
An adhesive is a substance designed to stick to surfaces and bond them together. It can come in various forms such as glue, cement, gum, paste, or tape. Adhesives can be derived from natural or synthetic sources, each with unique properties suited for different applications. Depending on their composition and intended use, adhesives display diverse characteristics, including strength, flexibility, and resistance to environmental factors.
Types of Adhesives
PVA

PVA glue, also referred to as wood glue or white glue, is available in liquid or paste form, typically clear or white. Renowned for its non-toxicity, this versatile PVA glue is safe for use, even by children. Its rapid-drying nature facilitates the formation of a strong bond, making it a popular choice for different projects due to its accessibility and affordability. This adhesive can effectively bond various materials such as paper, cardboard, fabric, and wood, finding widespread application across industries including construction, woodworking, and crafts.
For optimal results, apply the adhesive to one of the materials you want to bond and wait 3 to 15 minutes at ambient temperature to allow some water to escape from the film. Then, assemble the parts and press for a few minutes to develop sufficient tack for maintaining the bond.
Epoxy Sealant
Epoxy sealants are specialised formulations designed for sealing and waterproofing applications. They provide long-lasting protection against water intrusion, chemicals, and environmental factors, making them ideal for construction, automotive, marine, and industrial settings.
Additionally, epoxy sealants offer exceptional adhesion and durability, making them highly effective for sealing joints, cracks, and gaps in various surfaces such as concrete, metal, and wood. They require proper surface preparation for optimal performance and adhere well to porous and non-porous surfaces. With their versatile applications and reliable performance, epoxy sealants are valued for their ability to provide durable and watertight seals in a wide range of conditions.
PA
Polyurethane adhesives (PA) are versatile glues employed for bonding various materials. Renowned for their strength and flexibility, they endure moisture and chemicals, favouring them in the construction and automotive sectors. Formulated from a blend of polyurethane resin and hardener, they come in clear, white, or black hues. Despite their robust qualities, they require approximately 24 hours to cure fully.
Moreover, PA adhesives are non-toxic and safe for use. Their ability to form durable bonds, coupled with their versatility and safety, makes them invaluable for a wide range of projects and applications across industries.
Silicone Sealant
Another versatile industrial adhesive is silicone sealant, commonly used for sealing joints and gaps in various industries, including construction, automotive, and electronics. Its flexibility and resistance to moisture and temperature extremes make it ideal for outdoor and high-heat applications. When choosing the appropriate adhesive for your project, make sure to select a durable silicone sealant that’s easy to use and water-resistant, especially for applications in damp or humid environments.
When applying silicone sealant, ensure the surfaces are clean and dry to promote adhesion. Use a caulking gun to apply a smooth, even bead along the joint, then smooth the sealant with a tool or finger dipped in soapy water to prevent sticking. Allow adequate curing time, typically 24 hours, before exposing the sealant to moisture or temperature fluctuations for optimal performance.
Industrial Super Glue

Industrial super glue offers unparalleled bonding strength, making it indispensable across various sectors. It’s a go-to solution for industries needing reliable, long-lasting adhesion. It efficiently joins materials like metal, glass, and ceramics in construction, enhancing structural integrity. Automotive industries rely on its robust adhesion for assembly and repair tasks, ensuring durability under extreme conditions. Manufacturers utilise it for quick fixes on production lines, minimising downtime.
To use it properly, clean surfaces thoroughly, apply a thin layer of glue, and press firmly for optimal adhesion. To make a well-informed purchase, opt for a high-bond industrial super glue, consider the materials you want to bond and think about the application environment.
Acrylic Adhesive
Acrylic adhesives are types of glue made from acrylic polymers, known for their strong bonding properties. They’re commonly used in various applications like woodworking, crafting, and even in industries like automotive and construction. These adhesives work by creating a durable bond between surfaces, forming a strong connection once they dry. They’re favoured for their versatility, resistance to heat and chemicals, and ability to adhere to a wide range of materials, making them a popular choice in many projects and manufacturing processes.
How to Remove Adhesive?
To remove adhesive, start by identifying the type of adhesive and the surface it is attached to. For water-based adhesives, soaking the area in warm, soapy water can help loosen the bond. For stronger adhesives like super glue or epoxy, acetone or nail polish remover may be effective, but make sure to test in a small area first to avoid damage. Gently scrape or peel off softened adhesive with a plastic scraper or credit card. For stubborn residue, use a commercial adhesive remover or rubbing alcohol. After removal, clean the surface with soap and water to remove any remaining residue.
