How to Control and Monitor Your Coagulant for Latex Dipping?

Manufacturer: How to control and monitor our coagulant? Our coagulant temperature is about 35ºC.

John Woon (Senior Latex Consultant): All freshly prepared coagulant should be allowed to mature for at least 24 hours before use otherwise the wetting property would not be even over the entire surface of the former.

Your coagulant temperature is considered too low. You need the temperature to be high enough so that once the former is fully withdrawn from the coagulant tank, the coagulant on the former must immediately “set” (i.e. sufficiently dried) so that there is no flow-back of the coagulant on the formers.

This is to ensure an even coating of coagulant and hence the subsequent latex pick-up. I suggest you experiment with higher coagulant temperature, say, 45ºC to 55ºC. But before you do this, determine the “cloud point” first. The coagulant temperature should be about 2ºC above the cloud point.
