STRUKTOL® Aktivator 74

STRUKTOL® Aktivator 74 by Struktol is a vulcanization activator. It is a blend of zinc soaps of aliphatic and aromatic carboxylic acids. This cure additive is used in sulfur cure systems in many diene rubbers. When used in NR containing compounds an increased reversion resistance is obtained. It improves physical properties results in higher state of cure and increased modulus. It has a beneficial influence of dynamic properties, lower tan delta has been observed and a reduced heat build up on flexing due to better resistance to reversion may be obtained. It enhances processability, improves flow properties in NR containing compounds. It is also an effective peptizer for the mastification of natural rubber. It can partly or totally replace conventional activators based on fatty acids like stearic acid, zinc stearate, and zinc 2-ethylhexanoate. Recommended dosage level is 2-4 phr. The shelf life of STRUKTOL® Aktivator 74 product is 24 months.
