Thanecure® ZM
(formerly known as Caytur® 4*)
An Activator/Accelerator for Sulfur Curable Polyurethane Rubber
MSDS documents are available on our
Download page.
Thanecure ZM is a cure activator for sulfur cured Millathane® polyurethane
rubber. It consists of a partial complex of zinc chloride and MBTS. The
improvement in the physical properties of Millathane E-34 is shown in the
table below. Increasing the amount of Thanecure increases the rate and state
of cure and improves the compression set resistance.
For the most practical applications, 1.0 part of Thanecure ZM provides a
good balance between cure rate and processing safety. As the concentration
of Thanecure ZM increases above 1.0 part, cure rate improves only slightly
with reduced processing safety.
If it becomes necessary to increase scorch time for greater processing safety,
MBT level can be reduced to 1.0 phr without changing the amount of Thanecure
ZM.
Zinc oxide is not compatible with some polyester polyurethane rubber. Thanecure
ZM, which contains active zinc, needs to be incorporated to insure proper
state of cure. Thanecure ZM is used to cure both polyester (e.g., Millathane
76, Millathane HT) and polyether (e.g., Millathane E34, Millathane CM) and other types of sulfur curable
polyurethane rubber.
