EXTREM® by Merard S10 Polishing Compound

Developed by Merard, S10 EXTREM® polishing compound is formulated specifically for materials that typically present extreme challenges for high-polish finishing. EXTREM compounds are ideal for ceramic coatings such as HyCeram® and LuxArt®. The unique combination of ceramic and diamond components in this compound, called Cerax, was developed by Merard to deliver fast, effective, high-quality polishing. This S10 grade (light purple) is intended for surface preparation on the materials and should be used on high-quality, fine-thread cotton buffs such as Merard KH cotton buffs or on traditional Merard STV or felt buffs. Choose S20 grade for initial finishing and S30 grade for final finishing (not included; available separately). Each grade is color-coded for easy identification.

EXTREM® by Merard polishing compounds are designed for jewelers and watchmakers. They are manufactured from a proprietary formula of ceramic and diamond abrasives branded as Cerax. Cerax delivers consistent results and dependable performance when finishing high-hardness, extreme configurations such as ceramic coatings (HyCeram, LuxArt), PVD coatings, semi-precious gemstones (with a Mohs hardness 4–7), and metals such as platinum.
