OROPON OO – Bating agent

Edition 2009

OROPON® OO – Bating agent Features

OROPON® OO is based on pancreatic enzymes. OROPON® OO is active between pH 7 and 9. Handling & storage: Wear gloves and face mask during handling. CLOSE SACK TIGHTLY AFTER USE AND STORE IN A DRY PLACE. Can be stored for about 2 years (from date of production) if kept in a dry place and protected from heat above 30°C.

Benefits

OROPON® OO is suitable for any type of leather, especially for soft leathers. OROPON® OO ensures good scud-loosening. OROPON® OO gives a more elastic-grain without the tendency of loose grain. OROPON® OO slackens hide structure gently without causing an excessive decomposition of the flanks.

Application

OROPON® OO is added, undissolved, 20 – 60 minutes after the deliming agents. The deliming agent should be dosed in such a way that the pH value of the bating liquor remains within the desired range (pH 7 – 9), whilst providing the desired degree of deliming. The pH value should not be allowed to drop below 5, since otherwise scud fixation may occur and the outer layers of the pelt, particularly the grain, may be damaged due to acid swell. For improved scud release, compatible surfactants, e. g. BORRON®, may be added to the bate. The bating effect is more pronounced at higher, e.g. 37°C, rather than at low temperatures. For a uniform bating effect with gentle treatment of the grain, extend the bating period at lower temperatures; say 30 – 32°C.
