Ultraflexâ„¢ 4320
1 of 5 products in this brandUltraflexâ„¢ 4320 is a solvent-based adhesive that can be used as a one- or two-component system. It has a high heat activation temperature and offers high green strength, which means it provides strong initial bonding even before full curing. It is designed for sole and upper bonding in the footwear industry. Additionally, it is worth noting that Ultraflexâ„¢ 4320 exhibits excellent green strength even when used at a lower concentration than the recommended amount.
