Usage:
- Mode of action: MBT-80 is a semi-ultra, multi-purpose accelerator with a long plateau effect. It provides vulcanizates with good physical properties. In sulphur-free compounds MBT-80 acts as an anti-scorch agent, in CR compounds as a retarder. MBT-80 is activated by basic accelerators such as aldehyde-amine and guanidine etc., and by thiurams and dithiocarbamates.
- Dosage in NR and SBR:
primary: 1-2 phr with 2-3 phr sulphur
secondary: 0.5-1 phr with 0.2-0.3 phr Rhenogran TMTD-80 and 1.5 phr sulphur without sulphur: 0.5 phr with 3-4 phr Rhenogran TMTD-80
- Dosage in IIR:
0.5-1 phr with 0.5-1.5 phr Rhenocure TMTD-80 and 1-2 phr sulphur
- Application: mechanical articles of all kinds, e.g. treads, carcasses, air hoses, conveyor belts, driving belts, hoses, cable insulations.
