Resulting Properties
The above formulation can produce high quality hot melt adhesive that is preferable to EVA adhesive for wood bonding and particularly profile bonding in the furniture industry. Past mPO polyolefins could not be used in this application due to insufficient cohesion and insufficient open times or processing times. The above formulation provides a nonreactive hot melt adhesive based on mPO polymer that solves these problems.
