lijmtypes

Lijmtypes are the various adhesive families used to bond materials. The choice depends on substrates, required bond strength, exposure to moisture or heat, flexibility needs, and curing time. Good adhesion also requires surface preparation and proper application conditions. Adhesives can be grouped by chemistry, curing mechanism, and intended use, each with distinct advantages and limitations.

Water-based adhesives, including polyvinyl acetate (PVA) and starch-based glues, are common for wood, paper, and crafts. They are easy to apply, have low odor, and are generally inexpensive, but their water resistance and durability vary and may decline when exposed to moisture or heat.

Epoxy systems consist of resin and hardener that cure chemically to form strong, durable bonds with metal, concrete, ceramics, and composites. They offer good gap filling and chemical resistance but can be rigid, sensitive to mixing ratios, and have longer cure times.

Cyanoacrylate adhesives (super glues) cure rapidly and work well for small parts and fast repairs. They bond many materials but can be brittle, have limited heat resistance, and some plastics may craze or discolor.

Polyurethane and silicone adhesives provide moisture resistance and flexibility. Polyurethane bonds well to wood and plastics and remains somewhat flexible after curing; silicone is excellent for weatherproof sealing and bonding dissimilar materials but is generally less strong as an adhesive.

Hot melts and UV-curing adhesives offer rapid bonding: hot melts set with heat, UV adhesives cure under light for fast assemblies in electronics and packaging; both require compatible substrates and careful handling. Safe handling, ventilation, and reading manufacturer data sheets are essential across all lijmtypes.
