Various additions are used in rubber compounds to accelerate mixing with particulate fillers and to improve behaviour in subsequent processing operations. Cationic surfactants of general structure [RNH2(CH2)3NH3]2+ 2[R’COO] can be used in rubber processing as multifunctional additives (MFA) which act as processing aids, accelerators and mould releasing agents. However, with all these beneficial properties an adverse effect of decreased scorch time was observed when N–tallow–1,3 diaminopropane dioleate (EN444) was used in the filled natural rubber compound.
