Benefits OROPON
®
OR is suitable for any type of leather, especially for soft leathers. OROPON
®
OR ensures good scud-loosening. OROPON
®
OR gives a more elastic-grain without the tendency of loose grain.
OROPON
®
OR slackens hide structure gently without causing an excessive decomposition of the flanks. OROPON
®
OR is especially suitable for raw hides with high fat content.
Application OROPON
®
OR 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 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.
