Filter press plates, used in a number of applications including dewatering products in the pharmaceutical industries, usually take more than 24 hours to produce because the sealant used to hold filter press cloths in place during filtration cures very slowly, according to Whitford.
In response, the global company has developed a sealant that cures in 10 minutes (and at low temperatures), so filters can be dispatched within the hour, cutting production times and saving the valuable space previously taken up by drying filter press plates.
The new sealant, called Eternitex 64-010, also provides a number of additional benefits for manufacturers of filter cloths, including quick and easy application, minimal wastage, and durability.
Helen Brain, Whitford's product and process development chemist, said: "It is an environmentally-friendly, waterborne coating that can be used on a range of woven filters including polypropylene, polyester and polyamide fabrics."
