Actmix® DOTG-75GA F140

HSP Distance with DPIP: 0.9
Actmix® DOTG-75GA F140 is a di-o-tolylguanidine (75%). Acts as a vulcanization accelerator. It can lead to a very slow start of vulcanization and relatively slow vulcanization rate. Improves cross-linking density and vulcanization rate and provides excellent mechanical and anti-aging properties on combination with thiols, sulfenamides, thiurams and dithiocarbamates. It will be non-blooming in vulcanizates. Its recommended addition level in natural rubber is 0.8-1.2 phr with 2.5-4 phr sulfur, for SBR 0.1-0.4 phr with 1-1.5 thiols and 1.5-2.5 phr sulfur and for NBR 0.05-0.4 phr with 0.8-1.5 sulfenamides and 1.5-2.4 sulfur. Used in rubber industrial products.

Hansen Solubility Parameters

[19.4, 5.8, 3.6]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Actmix® DOTG-75GA F140. A practical determination of these HSP values would provide higher certainty. Learn More.
