Epoxy and adhesive
Short answer
An adhesive is a substance that bonds surfaces by adhesion and cohesion, used for tiles, laminates, and repairs. Epoxy is a two-part thermosetting resin that cures to form a strong, hard, cross-linked solid with excellent adhesion to concrete, metal, and glass, high strength, low shrinkage, and chemical resistance; used for structural bonding, crack injection, grouting, and coatings.
What is epoxy and adhesive?
Adhesive
An adhesive is a substance that joins two surfaces and holds them together by sticking to them (adhesion) and by its own internal strength (cohesion). Examples: animal glue, starch paste, gum, synthetic resin glues, cement-based adhesive and epoxy. Adhesives are used for fixing tiles, laminates, wood joints and flooring, and for repair work.
Epoxy
Epoxy is a thermosetting synthetic resin supplied in two parts, resin and hardener. When they are mixed, a chemical reaction forms a very strong, hard, cross-linked solid.
- Excellent adhesion to concrete, metal, glass, wood and stone.
- High strength, small shrinkage, and resistance to water, chemicals and abrasion.
- Used for bonding old and new concrete, crack injection, grouting of anchors, floor coatings, tile adhesives and fibre-reinforced polymers.
Epoxy is therefore a special, high-performance structural adhesive.
