Product Description

Core assembly adhesives have to meet very complex requirements. They need to provide a long open time, a fast build-up of cohesion (handling strength), high heat resistance, and excellent process reliability.
More and more frequently, core packages are assembled with thermoplastic polyolefin (PO) hot melts. Compared to standard polyamide (PA) hot melts which have been the standard product for this application for many years, PO hot melt adhesives are characterised by significantly better oxidation stability. This leads to substantially reduced production downtimes due to maintenance and cleaning work or malfunctions, and increases the reliability of processes.

Jowat-Toptherm® 238.97 is a new high performance PO hot melt adhesive which has been developed specially for the assembly bonding of core packages. The innovative formulation provides an extended open time while also ensuring a fast build-up of cohesion and excellent heat resistance. The immediate handling strength of the adhesive supports the high degree of automation introduced in many foundries, and facilitates short process cycles in the bonding of core packages.
