Its superior design and excellent tackifier resin compatibility give Solprene® 4302 optimal balance between adhesive strength, cohesive strength, and viscosity. Dynasol has announced plans to increase production of Solprene 4302 to keep up with growing demand for the new product.
Solprene 4302 was optimized specifically for the PSA and Non-PSA market, but can also be useful in asphalt modification for roofing and paving. “The secret to Solprene 4302’s success is the optimal structure design and balance with di-block content,” says Dr. Walter Ramirez, director of technology at Dynasol. “The structure provides an excellent balance of cohesive strength, adhesive strength, and viscosity, making 4302 useful in a wide range of adhesive applications.”
Dynasol’s latest innovation provides superior adhesive properties and high-temperature resistance; additionally, its viscosity balance reduces processing temperature and increases extruding rates, helping to optimize operation costs. Solprene 4302 is already being used in adhesive formulations for tapes, labels, sprayable adhesives, packaging, disposables, and foamed polymers for mattresses and furniture assembly.
Solprene 4302’s optimal structure can also help for faster formulation development, shortening product-to-launch cycles. A South American client recently partnered with Dynasol to develop a solvent-based, sprayable adhesive formula to replace an adhesive formula based in Polychloroprene rubber. Using Solprene® 4302 as a starting point, Dynasol collaborated with the client to develop a new adhesive formula that was commercialized in less than one week.
Solprene 4302 can also be used for asphalt modification in paving and roofing industries due to its performance in low temperatures and impact resistance. “Plus, because Solprene® 4302 is available in pellet form,” says Ramirez, “it’s easy to handle in all of these applications.”
