Recommendations for Applications:
STR70 is a very effective dispersing aid for white fillers. It is particularly effective in highly loaded Silica compounds.
STR70,if applied at the recommended dosage,does not bloom from vulcanisates due to its high solubility level.
In the presence of silane coupling agents, STR70 should be added after the silanisation process is completed.
