New Solprene grade for adhesive formulations

"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 optimise 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. It 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 on polychloroprene rubber. Using the 4302 grade as a starting point, Dynasol collaborated with the client to develop a new adhesive formula that was commercialised in less than one week.
The product can also be used for asphalt modification in paving and roofing industries due to its performance at low temperatures and impact resistance. It is available in pellet form and therefore easy to handle. Dynasol already announced plans to increase production of Solprene 4302 to keep up with growing demand for the new product
