Contactlijmen

Contactlijmen, often referred to in English as contact cement or contact adhesive, are one‑component adhesives designed to bond when the coated surfaces are brought into contact. They cure by drying the solvent or moisture contained in the film, producing a strong, immediate bond on contact. Most formulations are based on neoprene or other synthetic rubber resins, sometimes with polyurethane or acrylic components; modern variants may be water‑based or low‑VOC.

Application and working principle: Both bonding surfaces are coated, then allowed to dry to a tacky film. When the surfaces are pressed together, bonding occurs instantly. Alignment must be established before contact, as repositioning after bonding is limited. They work best on non‑porous materials such as laminates, veneers, rubber, metal, and certain plastics, but are less effective on porous substrates without surface preparation.

Common uses: They are widely used in furniture manufacturing for laminates and edging, veneer bonding, automotive interiors, shoemaking, signage, and various crafts and DIY projects that require quick, strong bonds between non‑porous materials.

Types and methods: Available as brush‑on, roll‑on, or spray formulations. Solvent‑based variants are common and offer strong bonds but emit volatile organic compounds and require good ventilation; water‑based versions reduce fumes but may have different temperature and moisture resistance. Some products include activators for specific substrate compatibility.

Advantages and limitations: Contactlijmen provide high initial tack and strong, durable bonds on suitable materials. Limitations include fumes and flammability for solvent variants, variability with heat and humidity, potential bond failure on porous substrates, and difficulty correcting misalignment after contact.

Safety and handling: Use in well‑ventilated areas, away from ignition sources. Wear gloves and eye protection, follow label instructions for curing times and disposal.
