QUICKBOND™ CC4058-PLUS: Lower Temperature Heat-Activated Bonding Water-Based Polyurethane Adhesive
Heat-activated bonding with polyurethane water dispersion (PUD) are characterized by the heat-activation or heat melt-flow temperature. The heat activated temperature is designed into the polymer molecularly structure designed into the PUD. Coral Industries of AIT Chemical Inc. further enhanced the PUD polymer structures with additional capabilities of different heat melt bonding temperature ranges from 50ºC to 90ºC for different application conditions.
- QUICKBOND™ CC4058-PLUS is modified to incorporate the ability of “wet-bonding” besides dry heat-activated bonding and capability to bond the notoriously difficult to bond EPE/PE and EPP/PP with primer or pre-treatment.
- QUICKBOND™ CC4058-PLUS has all the same properties of QUICKBOND™ CC4158-PLUS but with heat-activated bonding temperature designed to start around 50ºC. In contrast, QUICKBOND™ CC4158 melt-bonding after drying after dispensing at 70ºC and above.

QUICKBOND™ CC4058-PLUS is a low viscosity creamy white polyurethane-based water dispersion that can be used for dry heat-activated bonding or “wet bonding” that can achieved the same performance for porous foam or substrate bonding. While heat melting bonding can be as low as 50ºC, when heat-activation with adequate pressure to induce melt-flow, it maintains strong bonding to well above 70ºC.
Dry Heat-Activated Bonding for High Shear Strength and High Productivity:
Like QUICKBOND™ CC4158-PLUS, QUICKBOND™ CC4058-PLUS can be dispensed onto one side of the substrate and allow to ambient or heat drying to form dry film and ready for heat-activated bonding with contact pressure like any heat-activated polyurethane water-based adhesive. The heat-activated temperature is from 60-80ºC. Higher temperature required less pressure to induce adequate melt-flowing to form strong bonding with more area melt-flow coverage.
Heat-activation bonding of QUICKBOND™ CC4058-PLUS for lamination of structural parts to include forms of moisture and water barrier made of EPE and EPP foams, and/or PE and PP sheets. This is previously not possible with traditional heat-activated water-based adhesives.
To expand the range of applications based on different processing and application temperature requirements, AIT Coral Industries also created companion products to QUICKBOND™ CC4058-PLUS. and QUICKBOND™ CC4258-PLUS has lower temperature and higher temperature activation than QUICKBOND™ CC4158-PLUS respectively.
Wet Bonding as Water-Based Contact Adhesive Maintaining High Bond Strength Up to 70®C and Beyond:
QUICKBOND™ CC4058-PLUS like its famous sister product QUICKBOND™ CC4158 can be used as contact adhesives. When used to attach one-side porous substrate to another porous or non-porous substrate, they can be dispensed on one side and IMMEIDATELY assembled to quickly achieve handling strength within minutes. When used for bond less porous substrate, once the water-based adhesive on the substrate becomes transparent and tacky, they can be assembled with immediate handling strength.
Once fully “cured” when the water is fully removed from the adhesive, high shear bond strength of over 1,000 psi is achieved while maintaining over 200 psi at 55ºC and over 100 psi at 70ºC. Besides its typical usage of bonding fabrics, PU and EVA foams, natural and synthetic leathers onto different substrates, QUICKBOND™ CC4058-PLUS enables the bonding of all these substrates and foams to PE, PP, EPE, and EPP.
