Resulting Properties
The formulation presented here shows properties which make them highly desirable to be used in packaging applications. Unlike typical hot melt adhesives, this composition can withstand peel and shear loads at elevated temperatures for extended periods of time without experiencing catastrophic bond failure. The Aerafin 180 substitution provides an attractive balance of cost versus performance.
