Biocides Merpin 8000 and Merpin 8005 ensure a proper preservation of soaking floats and tanned leathers, hence avoiding delamination and mould damage.

Enzymatic auxiliary Merpizym 8008 accelerates the soaking of all kinds of salted and dried raw materials from bovine hides to sheep and goatskins by removing unstructured proteins and emulsifying natural fats. Merpin 8011 is especially recommended when processing partially dried or unevenly salted hides since it assures a very quick rewetting effect throughout the whole cross section. A well-balanced and low-foaming emulsifier Merpin 8010 N loosens and removes dirt and manure. By adjusting the pH in the soak with Merpin 8020 rather than with sodium carbonate or caustic soda, strong pH spikes are avoided and the swelling of the subsequently resulting pelts is reduced. All products when used in combination provide a uniform soaking effect, which is the perfect precondition for an even penetration of the liming chemicals.


The lipase-based degreaser Merpizym 4581 can be used as an additive in the liming or deliming float and thus improves the scud loosening and cleanliness. Merpin 6007 is an economical solution to reduce the sulphide load in conventional drum liming processes. For a higher level of swelling control, sulphide reduction and pelt cleanliness the application of Merpin 8016 N and especially the newly developed Merpin 9020 is highly recommended. Both products are sulphide-free and can be used in hair-pulping or hair-save processes with a hair filtration in the drum or paddle. They function as anti-wrinkle agents and improve the smoothness of the grain and scud loosening, resulting in a reduction of neck and belly draw, a reduced appearance of natural growth marks and thus in an improved overall classification of the hide material.
