Rinkal 1000

Bating agent
Technical Data Sheet

Product Review Rinkal 1000 is based on pancreatic enzymes. Rinkal 1000 is active between pH 7 and 9. Product Characteristics: Trade form at 20 °C Powder Appearance at 20 °C Yellowish to brownish pH- value (10 g/l ) Approx. 7 Benefits: Rinkal 1000 is free of ammonium salts. Rinkal 1000 is suitable for any type of leather, especially for soft leathers. Rinkal 1000 ensures good scud-loosening. Rinkal 1000 gives a more elastic-grain without the tendency of loose grain. Rinkal 1000 slackens hide structure gently without causing an excessive decomposition of t the flanks.

Application: Rinkal 1000 is added, undissolved, 20- 60 minutes after the deliming agents. For improved scud release, compatible surfactants may be added to the bate. The bating effect is more pronounced at high, e. g. 37 ·c, 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.
