Heat Sensitized Natural Rubber Latex

Manufacturer: One of our suppliers suggested that we should try Emulvin W and Coagulant WS from Lanxess to make our NR latex compound more heat sensitive in order to make thicker latex dipped products. We would appreciate if you could guide us on how to proceed.

John Woon (Senior Latex Consultant): Emulvin W ia a surface active agent (i.e. surfactant) which is an aromatic polyglycol and is normally added into the latex compound to improve the colloidal stability of the latex against mechanical shear and cationic chemicals. Although it appears oily it can be easily dissolved in water. I suggest you prepare a solution of about 20% before use.

Coagulant WS is a functional organosiloxane that is frequently used as a heat sensitizerfor latex compounds. While Coagulant WS reduces the "coagulation temperature" Emulvin W increases it.

Hence when Coagulant WS is used in conjunction with Emulvin W, the "coagulation temperature" of the latex compound could be changed to suit one's dipping process and also to control the thickness of the latex gel by varying the ratio of these two additives.

The advantage of Coagulant WS is the fact that it is silicone based (although water soluble) and hence it could also act as a releasing agent.

Training on Latex Technology.

Manufacturer: Please let me know if you do training on latex filming or general training on latex so that I can participate in near future.
Do you have any consultation fee or package system so that I can go through and work out more concerns in latex in a systematic way. Please let me know.
I look forward to hearing from you.

John Woon (Senior Latex Consultant):  I do conduct training on latex technology.

This can be done face-to-face or if required I can also put this into a pdf report for you. This covers the basic science and technology of natural rubber latex, latex specification and the significance of each parameter, latex stability, lab testing and many more topics.

The report would serve as a good reference guide for your work with natural rubber latex.
