Hotmelt adhesives (EVA hotmelt, PO hotmelt, COPA hotmelt)
There are two main types of industrial hot melt adhesives: ethylene vinyl acetate (EVA) and polyolefin or metallocene. EVA is a copolymer adhesive most commonly used in the paper, packaging, and assembly industries because they bond to a wide variety of cellulosic materials and have a wide range of formulations. The composition of the adhesive has a direct influence on its properties. Since they can be specially formulated for different uses, there are several types available on the market.
Reactive hot melt adhesives (PUR)
Reactive hot melt adhesives are processed in the same way as EVA and polyolefin hot melt adhesives. After rapid cooling, it provides green strength through a physical hardening process. A chemical cross-linking reaction is then initiated by moisture from the environment, which converts the adhesive into an elastomer. Reactive hot melt adhesives provide a stronger bond with better resistance to moisture, heat, and chemicals when they are finally cured.
PUR hot melt adhesives also form strong (covalent) chemical bonds with suitable reactive partners on the surface of the substrate. Increase in strength and adhesion area.
Dispersion adhesives (PVAC, EVA, PU)
Aqueous dispersion adhesives consist of a solid adhesive, usually PVAC and EVA, which is dispersed in an aqueous phase. Most of our adhesives are formulated with water-soluble and food-safe additives such as surfactants, emulsifiers, preservatives, wetting agents, plasticizers and adhesion promoters. The drying process is made possible by the environment, the substrates and the air. The adhesive must be completely dry for maximum strength. Small amounts of residual moisture or water-soluble additives can weaken the dry adhesive film and reduce its resistance to moisture and water.
Polyurethane and solvent-based adhesives are used to create strong and permanent bonds in a range of engineering applications.
Intercol has a range of 1-part PU adhesives and is primarily designed for construction applications.
Pressure sensitive adhesives (PSA hotmelt)
Intercol offers a wide range of hot melt pressure sensitive adhesives based on thermoplastic rubbers.
For almost all self-adhesive applications, pressure-sensitive hot melt adhesives are offered, from weakly to strongly permanent adhesive products. The main areas of application are self-adhesive labels, adhesive tapes and plaster products. For many industrial intermediate products such as sound insulation, packaging technology, self-adhesive technology often offers a technically intelligent and economical alternative to mechanical assembly processes.
The products are solid at room temperature and are offered either in blocks of 0.5, 1, 4, 8 and 20 kg in siliconized cardboard boxes, foil packaging or in siliconized cardboard drums weighing up to 175 kg.
Pressure-sensitive hot melt adhesives are liquefied using block or drum melters and, depending on the application, processed in a temperature range of 150… 180 ° C using commercially available roller or nozzle coating equipment.
