Ease of Application

AFFINITY™ GA  based hot melt adhesives are easy to apply and offer improved bead control, excellent bead cut-off and less spider web development which delivers dollars to the bottom line.  Adhesive based on AFFINITY GA polymers exhibit improved shear and viscosity stability due to Newtonian profile of the polymer over much of the useful shear rate range, as shown below.

AFFINITY GA POPs help produce HMAs that exhibit exceptional viscosity stability at the application temperature.  This outstanding viscosity and color stability allows for clean-running systems without the need to change the HMA in the tank, thus reducing overall cost.

This shear and viscosity stability is instrumental in delivering a product with improved bead control and excellent cut off.  The improved bead control delivers lower product usage and reduced cost.
