USING PRIMERS IN COMBINATION WITH ADHESIVE TIE-LAYER RESINS OR THEIR BLENDS TO MAKE STRUCTURES WITH UNIQUE PERFORMANCE.

摘要

We have blended adhesive tie-layer resins with commodity resins and made structures with excellent adhesion and water resistance. Primers were critical to success and good results were obtained even at very low extrusion temperatures. Potential benefits include improved adhesion, water resistance, processability and productivity. We also tested unblended adhesive tie-layer resins, such as those used in the co-extrusion process. Adhesion and water resistance were greatly improved by using primers.
