As it has low astringency the fine pattern of grain is preserved. Rockytan ROS imparts a soft handle to leather and in combination with vegetable tannins, it brightens the color of leather.
It has a good levelling effect on dyes. Leather retanned with Rockytan ROS show a good buffing and embossing properties. Its better filling effect takes place when used in combination with resin tanning materials like Rockytan RR7.
