Compared with the coolant WS-23, it is more delicate and easier to dissolve. We developed a proprietary process to provide the WS-27 with a high purity product that does not have the bitter aftertaste of previous products. It mainly affects the front of the mouth and the tongue. And it has a high burst and high intensity of cooling sensation, suitable for a variety of products.

CAS : 10222-01-2 HS Code : 29209090 Packing : 25kg/Drum Application Product Name: 2,2-Dibromo-2-cyanoacetamide 20%, DBNPA 20% CAS No: 10222-01-2 Appearance: Colorless to yellowish transparent liquid Property: DBNPA aqueous solution is stable under acidic conditions and easy to hydrolyze under alkaline conditions. Increasing the pH value, heating, and irradiation with ultraviolet light or fluorescence can greatly speed up the dissolution rate. It is easy to be reduced by reducing agents, such as hydrogen sulfide debromine and become non-toxic cyanoacetate amine, which greatly reduces the bactericidal rate Application: DBNPA is a broad spectrum and efficient industrial fungicide to prevent the growth and reproduction of bacteria and algae in paper, industrial circulating cooling water, metal processing lubricants, pulp, wood, paint and plywood. Can be used as a sludge control agent, widely used in paper mill pulp and circulating cooling water systems. As a broad spectrum and efficient biocide, it can quickly penetrate the cell membrane of microorganisms and be used for certain protein groups, so that the normal REDOX of cells is suspended, thereby causing cell death.
