The characteristics of the treated buffs

Let’s extend a buff’s life. Treatment unconditionally gives a buff 1.3 ~ 2 times longer life.

Why do you need treated buffs?
1. Increase the endurance of buffs by enforcing fiber.
2. Increase the polishing efficiency by providing hardness.
3. Increase the preservation efficiency of buff’s polishing compounds.
4. Increase combustible resistant by preventing from excessive heat of buff during operation.
< Kinds of treated buffs (Processing of untreated buffs with resin) >
Treatment Characteristics
Extremely hard surface. Assures fewer passes and lowest buff costs. Treatment can be applied to many types of sisal buffs.
Golden Hard
Harder than Golden with good preservation of polishing compounds.
First (Limipid treatment)
Long life with hardness.
Receive no change of hardness by polishing heat and increase life with good adhesion of buffing compounds to buffs.
Relatively hard … all purpose cutting. Exclusive treatment binds the fibers of any cotton or sisal buff together. Holds compounds better.
Super Yellow
Suitable for Sisal buffs. This treatment is relatively hard, and good for Steel or Stainless steel.
Provides a soft buff with coloring advantages, plus increased buff life.
No hard-to-reach crevices can escape this extra-flexible buff. Better coloring, polishing, greater compound retention, less buff cleaning.
Substantially increases buff’s ability to hold compound, thereby reducing buff cleaning. Assures finishing with fewer passes and longer buffs life.
Super Green
Suitable for Sisal buffs. This treatment is relatively soft, and makes a buff with good conformity to objects.
Big Red
Buff stays permanently tacky, but pliable-no brittleness! Treatment clings to the buff, not the workpiece. No residue or disintegration.
Produces a “not too hard, not too soft” buff which is ideal for many applications. Improves cutting, coloring, and compound retention.

Instructions for use

1. Peripheral speed of buffs
The peripheral speed of our treated buffs exercises maximum efficiency at 2400~2700m/min in normal case. Our treated buffs show more efficiency than the untreated buffs when they are used in a low speed since their cutting power is enhanced by our unique treatment effect.

2. Polishing pressure of buffs
Since the polishing ability of buffs can be increased by our buff treatment, our buffs' polishing effect exercises fully even at lower polishing pressure. This is a factor to increase the life of buffs, and also to reduce fatigue of the operator of manual polishing.
