Valco Meltons dispensing equipment can also be used for nearly any precision fluid handling requirement. Applications include liquids such as perfumes, inks, lubricants, structural adhesives and 2-part materials for spray or extrusion application, coating, metering, mixing and precision viscosity control. For more information, contact us today.

Valco Melton has been a leading supplier of cold adhesive dispensing systems to the packaging and converting industries since 1952. Thousands of machines worldwide have been converted from the old open glue pot and wheel to a Valco Melton gluing system. A sophisticated, electronic control system combined with an enclosed, pressurized glue application system results in quick, precise control of glue volume and pattern position onto product. To learn more, contact us today.

From over 60 years in the adhesive dispensing business, Valco Melton has developed a complete network of relationships with some of the best adhesive suppliers across the globe. As an additional offering with our partners, we can help you find the adhesive you are searching for. Quality, high performance waterborne and hot-melt adhesive formulations are available for all packaging and paper converting applications including low temperature (hot melt) packaging grades, breakaway (palletizing), fugitive and pressure sensitive, for coated and uncoated paper stocks. To find out more, speak with one of our adhesive specialists today.

Valco Melton offers sealants for applications such as engine assembly such as Hylomar, a non-hardening gasket dressing. To find out more today, ask us for additional information.

Cold Glues are water-based solutions. The adhesive solids are dissolved in water, usually by cooking. A bond is formed when almost all of the water is lost via penetration or absorption into substrates. To create a solid bond, it requires 2 absorbent surfaces. There are three main types of cold glue adhesives: 1. Starch-- A whiteoff-white opaque solution, usually low in solids2. Dextrine-- Depolymerized starches, usually tan to dark brown in color (pyrolysis), which enhance solubility, increase wet tack, lower viscosity andor increase solids, and improve solution viscosity stability.3. Polyvinyl Alcohol solutions (PVOH)-- A synthetic water soluble adhesive or intermediate, Translucent. The dry film it leaves can be water sensitive or water resistant. Advantages Excellent penetrationExcellent wet tack and tack rangeExcellent final adhesion to regular stocksExcellent heat and cold resistanceEasy to clean up with excellent machining characteristicsStorage conditions not critical - freezethaw stableLow price per wet pound - raw material relatedLimitations Slow setting speed Poor adhesion to difficult surfaceCaution required when dilutingMust be protected from bacterial and fungal attack

Hot Melts are 100% non-volatile thermoplastic materials, solid at room temperature, melted to the application temperature desired, and applied in the molten state. A bond formation is obtained by cooling the substance to solidify after the wetting and penetration of both surfaces. Packaging and converting grade products are based on EVA. Hot Melts are formulated to provide desired adhesion, speed of set, open timebonding range, and heat andor cold resistance properties. Use of the highest quality raw materials with formulation compatibility yield excellent thermal stability and consistency of application and performance. Advantages Fast set speeds - high through putAdhesion to difficult or non-porous surfaces, wax coatings, poly-laminated stocks, plastics, etc.Water resistant Excellent glue line control No special storage conditionsGap filling (100% solids)Limitations Temperature sensitivity Special equipment requirements -- correct settingsadjustments is critical to performanceLow penetrationLimited toughness
