Lamination Adhesives improve holdout when aerated.

Press Release Summary:



Aerobond 32-192A and 12-200A adhesives are able to contact substrate surface without flowing down and away from where bonding should occur. Type 32-192A is for Automatan and similar laminating equipment; 12-200A formulated dextrin adhesive is for general purpose laminating. Both should be applied with nip rollers.

New Specialty Adhesives for Laminating Feature Improved Hold-Out


BRIDGEWATER, NJ-Two new specialty adhesives for laminating exhibit improved hold-out when they are aerated. It refers to the adhesive's ability to be available to contact the substrate surface without flowing down and away from where bonding should occur. "In the quest for dispensing precisely the optimum amount of adhesive, many laminators have considered using foamed or aerated adhesives, says David Lydzinski, business manager, AEROBOND adhesive. Dispensing neither too much nor too little ensures good bond strength while preventing warping due to excessive moisture, and minimizing cost.

By relying on a new product called AEROBOND 32-192A hybrid adhesive, laminators who convert paper products minimize moisture and cost as well as permit high-productivity processing. "This specialty adhesive which was designed for Automatan and similar laminating equipment also exhibits superior foam stability, allowing for high quality paper laminating," added Lydzinski. "This performance benefit results in trouble-free processing, enabling plant personnel to focus on other tasks," he added.

New AEROBOND 12-200A formulated dextrin adhesive has been created for general purpose laminating where hold out and foam stability are needed. Though this product was designed to be aerated, it can be used without foaming.

The manufacturer, National Starch and Chemical Company, recommends nip roller application for both of these adhesives. Technical data on the percent solids, viscosity, pH, density and appearance are available on technical service bulletins available free of charge from the manufacturer.

National Starch and Chemical Company, a member of the ICI Group, headquartered in Bridgewater, NJ, is a worldwide manufacturer of adhesives, specialty polymers, electronic and engineering materials, natural polymers and advanced ingredients, with sales of $2.8 billion.
