The MIRECIDE® range of biocidal products
It is highly effective in preserving from contamination
and deterioration due to harmful microorganisms,
such as bacteria and fungi.
LAMIRSA is the leading European and one of the world’s leading producers of the synthesis of TCMTB (2-(thiocyanomethylthio)-benzothiazole), a fungicide for the leather industry.
In addition, it develops the MIRECIDE®-KAP range of microencapsulated biocides, manufactured with an advanced, versatile and efficient microencapsulation technology for dry-film protection.
MIRECIDE – KAP/800
ENCAPSULATED TCMTB BASED ANTIMICROBIAL FOR THE LEATHER INDUSTRY
PROPERTIES
MIRECIDE-KAP/800 is a VOC Free product in aqueous medium based on encapsulated 2- (thiocyanomethylthio) benzothiazole (TCMTB), specially created to avoid the microbiological development causing significant damage in the tanning process, such as hair loss, collagen decrease, leather spots, etc.
As the active TCMTB is encapsulated and in an aqueous medium, it considerably reduces the danger in the handling of the product, and offers numerous advantages in the efficacy results in the conservation of the leather over time.
MIRECIDE-KAP/800 has a broad microbiocidal spectrum, especially for mould-causing fungi, whose proliferation is favored by various factors such as pH, humidity and work temperature, existence of nutritional substances in the medium, etc.
The product can be applied in the various stages of the tanning process such as soaking, pickling, tanning and retanning.
INSTRUCTIONS FOR USE AND RECOMMENDED DOSES
MIRECIDE-KAP/800 is effective and stable at slightly acidic and neutral pH values, presenting a slight loss of activity at pH values below 3.0 and above 8.5. The addition of MIRECIDE-KAP/800 must be separated from the incorporation of the basifying agents, since such extreme conditions of pH (10-10.5) can cause the degradation of the TCMTB molecule and therefore decrease its protective character. The dose of use will depend in each case on the existing contamination and its particular conditions, so our recommendation is to carry out preliminary tests in the laboratory to verify the compatibility and efficacy of the product in the medium in which it is to be used, as well as establishing the optimal dose of treatment. However, and for guidance purposes, in the various processes the doses range between 0.02 – 0.3% on leather to be treated.
The product can be dosed as it is or with in-line dilution using stainless steel or teflon pumps.
REGULATION
LAMIRSA is included in the ECHA list in accordance with article 95 of the BPR (Regulation 528/2012 on biocidal products) as a supplier of TCMTB for use as a protector of fibers, leather, rubber and polymerized materials.
The product can be dosed as it is or with in-line dilution using stainless steel or teflon pumps.
TCMTB, the active ingredient in MIRECIDE-KAP/800, is approved by the US Food and Drug Administration (FDA) and the German BfR to be used in the manufacture of paper and cardboard in contact with food. TCMTB is included in the Code of Federal Regulations in its section 176.300 (“slimicides”), as well as in the BfR Recommendation (Chapter XXXVI, B, VII b, 11), maximum 4.5 ppm based on dry fibre weight.
TCMTB also complies with the basic criteria for the concession of the ecological label according to “Blue Angel”, according to the RAL-UZ-148 standard for tanning, allowing its use in the final skin up to 500 ppm (considering the TCMTB and its degradation product – MBT).
