Lijmtype

Lijmtype is a term used in materials science and industry to describe a family of adhesive products designed to form fast, durable bonds across a range of substrates. The term combines the Dutch word lijm, meaning glue, with type to indicate a category rather than a single product. In practice, lijmtype denotes adhesives formulated with polymer matrices that cure through moisture, heat, or ultraviolet radiation, depending on the formulation.

Common compositions include polyvinyl acetate, acrylic, polyurethane, and cyanoacrylate chemistries. Many lijmtypes are delivered as liquids but may also appear as gels or pastes. Some formulations incorporate fillers, tackifiers, or adhesion promoters to improve wetting and bond strength on difficult surfaces.

Bond performance depends on substrate compatibility, surface preparation, and curing conditions. Typical advantages claimed for lijmtype products include fast initial tack, high shear strength, and good gap-filling capabilities, though properties vary widely across formulations. Environmental resistance, including moisture and temperature stability, is often cited as a differentiating factor.

Common applications include woodworking, packaging, textiles, automotive interiors, and electronics assembly. Lijmtypes are chosen for open time, curing speed, and bond-line flexibility relevant to the intended use.

Manufacture and testing follow standard practices governed by ISO and ASTM guidelines. Product data sheets provide performance specs like cure time, hook strength, and shelf life. Safety considerations include flammability, solvent content, and irritation risks; appropriate ventilation and protective equipment are advised.

The term lijmtype is primarily descriptive rather than brand-specific and may be used in industrial catalogs to categorize adhesives with similar cure mechanisms.
