Adhesives

About Cold Seal Adhesives

People actually refer to this class of product using three different names—cold seal adhesives, self-seal adhesives, and cohesives. Remember that all the terms describe exactly the same material.

Measuring Force

Learn what adhesion is, how it is measured, what a test really measures relative to the true adhesion between two surfaces, how adhesion affects the performance of the final laminated or multilayer product, an ideal adhesion test between two materials, and what the common T-peel adhesion test measure.

Give Customer What He Wants

Too many times converters make substitutions when filling orders from their customers, with serious consequences. The customer will be unhappy unless he receives exactly what he ordered.

Hot Melt Adhesive Use

Hot melt adhesive use continues to grow due to unique properties including ease of use, adhesion to a wide variety of surfaces, strength properties, aging characteristics, etc. By some measurements, hot melts are among the fastest growing adhesives in the industry.
