The Liquamelt adhesive is cool until you need it then activated at point of application by the Liquamelt dispensing machine. When it’s activated, the foamed thermoplastic adhesive expands to cover more surface area with less adhesive for more than a 50 percent improvement in mileage. How it works

Liquamelt is an adhesive system that does away with the tanks, melters, sensors and hoses associated with traditional hot melt applications - resulting in energy savings of up to 50 percent.

Liquamelt offers the convenience and safety of cold glue with the speed and performance of hot melt. It’s a smart alternative that can be used in case and carton sealing, tray forming, paper assembly and other assembly applications that require a robust, rapid-set thermoplastic bond. A four-channel unit is capable of processing 35 lbs per hour - the equivalent of 70 lbs per hour of hot melt.

Converting to Liquamelt is simple. Replace existing hot melt tank, hose and dispensing heads with the Liquamelt pump unit, conventional hoses, and dispensing head assemblies designed for retrofit. Start the unit up in less than 20 minutes—and run with Liquamelt.

At every step, Liquamelt drives costs out of the production line.

It goes twice as far

The formulation of the adhesive combined with the foam activation process, doubles adhesive mileage. Liquamelt goes twice as far per pound so you buy half as much—reducing your material, shipping and handling costs.

It’s hot-on-demand, not before.

Liquamelt is heated, mixed and dispensed on demand—removing the equipment, maintenance and energy costs of traditional hot melt technology.

It starts on a dime.

Start up time for Liquamelt is less than 20 minutes, compared to 35 to 90 minutes for hot melt.

It runs clean and steady.

No more charred material in hoses and tanks to slow down or stop production.

Clean up is fast.

Liquamelt has a non-reactive composition—making it easy to clean up at day’s end. Instead of scraping or scrubbing equipment, extra adhesive can be blown off or vacuumed up.

Many adhesives use petroleum-derived mineral oil as a liquid carrier; Liquamelt uses natural oils and contains more than 40% sustainable raw materials overall.

Compared to hot melt, Liquamelt reduces energy consumption and adhesive use by 50% or more.

Liquamelt uses less energy during manufacture and because you need less, reduces energy use during shipping and handling.

With a non-reactive composition, Liquamelt is much less hazardous to operators.

Take another look

The Liquamelt system was broadly commercialized when H.B. Fuller acquired the brand in 2011 and commissioned a dispensing system from Graco ®, the world leader in fluid dispensing technology.

The Liquamelt system is powered by Graco's ® reliable NXT air motor and proven piston pump design.

The new delivery system includes a pump, reservoir, and up to four hoses—each equipped with patented “TurboActivator™” technology.

Patented TurboActivator™ technology makes it hot-on-demand.

At the heart of the system is TurboActivator technology—a patented device that transforms a specially formulated liquid dispersion to a robust foamed thermoplastic adhesive—on demand.

The liquid dispersion is pumped through conventional (not heated) hydraulic hoses to the TurboActivator device, mounted just before dispensing heads.

The TurboActivator transforms the liquid dispersion to a foamed adhesive and dispenses the adhesive through zero cavity gun technology at a rate of 25 grams per head with a maximum of greater than 8 lbs per hour, per head.

When it is dispensed, Liquamelt is a high-molecular-weight, rapid-set, thermoplastic material that resists bond failures through a wide range of temperatures: from -40°F to 140°F (-40°C to 60°C )

Detachable Dashboard Integrates Simply

The Liquamelt system features a detachable, MOD (Manual Operating Display) keypad and monitor built with proven Graco-control technology.

Use the MOD for setting heat zones, multiple temperature recipes and start/stop parameters.

MOD includes a self-diagnostic function and integrates easily with existing packaging equipment.

New bulk feed options

Three bulk container sizes are offered: 30 liter drum, 50 gallon drum, and 2,500 pound tote.The bulk feed eliminates the need for on-floor staff to refill the adhesive reservoir. Typically hot melt adhesive is dispensed from the hot tank of a conventional system or from a reservoir close to the hot melt system.

The bulk delivery option allows containers to be located remotely and the Liquamelt adhesive to be safely transferred from the sealed containers to the packaging machines through common non-heated fluid hoses providing a closed, continuous fill operation. This is important in reducing waste, resulting in lower overall operating costs.
