What are the different types of adhesive?

ByAdmin

Adhesive grades vary based on their composition, properties, and intended applications. Here are some common grades of adhesives along with their differences and application examples:

  • Cyanoacrylate (CA) Adhesives (Super Glue):
  1. Properties: Fast-setting, high-strength, bonds well to a wide range of materials.
  2. Applications: Used for bonding ceramics, plastics, rubber, metal, and some types of wood. Ideal for rapid bonding in electronics, medical devices, and model-making.
  • Epoxy Adhesives:
  1. Properties: High strength, excellent chemical resistance, and good gap-filling capabilities.
  2. Applications: Suitable for bonding metals, glass, ceramics, wood, and some plastics. Widely used in construction, automotive, aerospace, and marine industries.
  • Polyurethane Adhesives:
  1. Properties: Flexible, durable, resistant to water and heat.
  2. Applications: Used in woodworking, construction, automotive, and footwear industries for bonding various materials, including wood, metal, plastics, and composites.
  • Acrylic Adhesives:
  1. Properties: Good weather resistance, UV stability, and high strength.
  2. Applications: Commonly used in signage, automotive assembly, aerospace, and structural bonding applications.
  • Contact Adhesives:
  1. Properties: High initial tack, good flexibility, and bond strength.
  2. Applications: Suitable for bonding large surface areas, laminates, veneers, and substrates where mechanical fastening is impractical. Used in furniture manufacturing, automotive interiors, and footwear.
  • Pressure-Sensitive Adhesives (PSAs):
  1. Properties: Adhere with light pressure, can be removable or permanent.
  2. Applications: Used in labels, tapes, graphic films, medical dressings, and various consumer products due to their ease of application and versatility.
  1. Hot Melt Adhesives:
  1. Properties: Solid at room temperature, melt and flow when heated, rapid setting upon cooling.
  2. Applications: Packaging, bookbinding, woodworking, product assembly, and non-woven bonding due to their fast setting and high bond strength.
  • Silicone Adhesives:
  1. Properties: Excellent resistance to extreme temperatures, weathering, and chemicals.
  2. Applications: Sealing and bonding in automotive, electronics, aerospace, and construction industries. Used for gaskets, sealing joints, and bonding heat-sensitive materials.
