M&G have developed a potassium stearate based antitack, supplied as a 20 or 25% paste form product. It has been widely accepted in the industry for over 4 years now by the Top 3 leading glove producers in the country manufacturing NBR gloves.
What are the main Advantages and Disadvatages of using a potassium stearate based antitack?
Potassium Stearate is soap, and have surfactant properties, and it is partially soluble in hot water. This is an advantage when former cleaning is concerned. The dosage used in a potassium stearate based powder free coagulant ranges form 0-8 – 1.2 % (as compared to 2.0 -2.5% for a calcium stearate based antitack) Less dosage means also less powder is deposited onto the formers, and being partially soluble in hot water, the formers are basically also self cleaning in the hot water, with a bit of surfactant added inside wash tanks.
Note: Glove have les or no powder marks
Disadvantage of using a potassium stearate antitack is it is a paste, and required multi stage preparation: it had to be diluted to a flowable form at 5-15%, and then mixed in with CaNo3 using a high speed HSD disperser, or homogenizer. Most glove factories may not have this facility….
