Glue (Adhesive)
Glue is a liquid or paste-like adhesive used to bond objects together. It consists of natural or synthetic polymers that are joined under the application of heat and/or pressure. Glue is used in a wide variety of applications, from woodworking and paper manufacturing to textile and footwear production.
Types of Glue:
-
Polyvinyl acetate (PVA) glue: Also known as white glue, widely used in woodworking, paper manufacturing, and textile industry. Water‑soluble and offers good moisture and aging resistance.
-
Polyurethane glue: Extremely strong and flexible, used for bonding wood, metal, leather, and other materials. Resistant to water, chemicals, and high temperatures.
-
Epoxy resin glue: Very strong and heat‑resistant, suitable for bonding metals, ceramics, and plastics. Resistant to moisture, chemicals, and heavy loads.
-
Acrylic glue: Fast‑drying and clear, used for bonding paper, cardboard, leather, fabric and other materials. Also resistant to moisture and aging.
Glue Application Process:
Glue is usually applied to one or both surfaces that are to be joined, then pressed together under heat or pressure. Some adhesives require heating or curing after application before they fully set and harden.
