Microencapsulated TCMTB – PAT. WO2022002846A1
The invention relates to a new process for preparing microencapsulated thiocyanomethylthio benzothiazole (TCMTB) by covering TCMTB droplets in an emulsion of an organic phase in an aqueous phase with a melamine-formaldehyde polymer coating to form solid TCMTB microcapsules. The invention further relates to the new TCMTB microcapsules and aqueous suspensions containing the TCMTB microcapsules and the use of microencapsulated TCMTB in tanning or for preserving hides, leather, fibers and polymerized material or for preserving paints, paper products, wood, wood products, or industrial water.
