EXTREM® by Merard S30 Polishing Compound

Developed by Merard, S30 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 S30 grade (cherry red) is intended for final finishing on these materials and should be used on high-quality, fine-thread cotton buffs such as Merard KH cotton buffs or on traditional Merard MOC-2 or STV buffs. Choose S10 grade for preparing surfaces for finishing and S20 grade for initial finishing; both available separately. Each grade has a different color, making it easy to pick up the compound you need. 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 (physical vapor deposition) coatings, semi-precious gemstones (with a Mohs hardness 4–7), and metals such as platinum. EXTREM polishing compounds are color-coded for easy identification.
