In daily life, various types of adhesives (commonly referred to as glue) are used for different purposes. Here are some common types:
White Glue (PVA - Polyvinyl Acetate):
Uses: Paper, cardboard, wood, and fabric.
Characteristics: Water-based, non-toxic, easy to clean, and dries clear.
Super Glue (Cyanoacrylate):
Uses: Plastic, metal, rubber, and ceramics.
Characteristics: Fast-drying, strong bond, and works well on non-porous materials.
Epoxy Resin:
Uses: Metal, glass, ceramics, and some plastics.
Characteristics: Two-part adhesive (resin and hardener), very strong and durable, resistant to heat and chemicals.
Hot Melt Adhesive (Hot Glue):
Uses: Crafting, packaging, and light-duty repairs.
Characteristics: Applied hot and solidifies as it cools, bonds quickly, and is easy to use with a hot glue gun.
Wood Glue:
Uses: Woodworking projects.
Characteristics: Strong bond for wood, available in various formulations like PVA, polyurethane, and hide glue.
Fabric Glue:
Uses: Textiles and fabric repairs.
Characteristics: Flexible, washable, and designed to withstand the stresses of fabric use.
Contact Cement:
Uses: Laminates, veneers, and rubber.
Characteristics: Applied to both surfaces, allowed to dry, and then pressed together for an instant bond.
Silicone Adhesive:
Uses: Glass, metal, and some plastics.
Characteristics: Flexible, waterproof, and resistant to high temperatures.
Spray Adhesive:
Uses: Photos, posters, and lightweight materials.
Characteristics: Easy to apply, provides a thin, even coat, and is repositionable before it sets.
Polyurethane Glue:
Uses: Wood, metal, ceramics, and plastics.
Characteristics: Expands as it cures, fills gaps, and is waterproof.
Rubber Cement:
Uses: Paper, photos, and art projects.
Characteristics: Flexible, repositionable, and can be removed without leaving residue.
Each type of adhesive has specific properties that make it suitable for particular applications. Choosing the right glue depends on the materials being bonded and the conditions the bond will be subjected to.
