A type of rubber neoprene adhesive that creates a fast, flexible and permanent bond. Parts get stuck on contact, takes a little while longer to harden completely
Very quick (no long drying time), high initial strength, Great flexibility in the product as well as an improvement in its aesthetics, Sealing function and protection against corrosion.
Initial bond might not be that strong, requires completely dust, dirt and moisture free surfaces
Cyanoacrylate adhesives, commonly known as instant or contact adhesives, are a category of thermoplastic adhesives known for a fast, reliable bond.
They are room-temperature curing adhesives available in a wide range of viscosities. They are typically used for high-performance bonding of numerous materials in seconds – rubber, polystyrene, wood, metal and plastics.
Same advantages and disadvantages of contact adhesives (they are a type of contact adhesive)
Epoxy resins are a type of thermosetting polymer adhesive. They are known for their high strength, chemical, electrical, temperature, moisture, and corrosion resistance
Once cured/hardened, they will not soften again under heat, as they are thermosetting
Epoxy resins often come in two parts: the resin and the hardener. The resin is the adhesive part, which takes a long time/high temperature to harden on its own.
The hardener is a catalyst that speeds up the hardening reaction of the resin. The two are mixed together so that they can be used in regular situations without high temperature ovens etc, low odour requires less ventilation
An example of a common epoxy resin is araldite
High strength, very good chemical, heat, electrical, and moisture resistance, long shelf life, bonds with many different materials
Takes a long time to cure, doesn't bond all types of materials, e.g certain plastics only, can be quite harmful/irritant to skin, bad for the environment when disposed of
