How to Control and Monitor Your Coagulant for Latex Dipping?
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 You need the temperature to be high enough so that once the former is fully withdrawn from the coagulant tank, the coagulant on the former must immediately “set” (i.e. sufficiently dried) so that there is no flow-back of the coagulant on the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.

Malaysian Glove Makers Rally on U.S. Health Bill
According to an article in bloomberg.com by Chan Tien Hin, "Top Glove Corp. rose to a record, leading a rally by Malaysian rubber glove makers on speculation President Barack Obama’s U.S. health bill will boost sales. Top Glove, the world’s biggest, climbed 2.9 percent to 13.30 ringgit at the close in Kuala Lumpur. Kossan Rubber Industries Bhd., the nation’s third-largest, increased 3.6 percent to 7.68 ringgit, and Adventa Bhd. gained 2.9 percent to 3.50 ringgit.
The benchmark FTSE Bursa Malaysia KLCI Index rose 0.4 percent. Obama’s $940 billion overhaul of U.S. health legislation subsidizes coverage for uninsured Americans, financed by Medicare cuts to hospitals and fees or taxes on insurers, drugmakers, medical-device companies and Americans earning more than $200,000 a year.
The bill may “lead to higher demand for examination gloves in the U.S. when Americans start to visit health-care centers more frequently,” Jason Yap, an analyst at OSK Research Sdn, said in a report today [March 24]. It will “put more strain on the supply of examination gloves, which is still catching up with demand.”

Water Resistance of Rubber Products
John Woon (Senior Latex Consultant): You are right in thinking that rubber products are water repellent but please bear in mind that this property for rubber only appears to be superior in comparison to alternative materials such as fabrics, paper, wood and leather.
There is an ASTM standard test for water resistance, similar to the total immersion procedure for oil resistance. Results are usually expressed as weight or volume change of the test specimen.
Compounding ingredients play more important parts than the rubber itself. As far as practically possible one should avoid hydrophilic materials. These water soluble ingredients might also lead to a drop in physical properties after exposure to water, hence the concern of your customer.
You have to ensure your processes include an efficient leaching section. You must use both cold and hot leaching.
