Hyprez Precision Lapping and Polishing Slurries

Why diamond?

• Reduce lapping times from hours to minutes
• Reduce slurry usage and waste from gallons to pints
• Achieve a reflective finish in a single step, eliminate hand polishing
• Cleaner process, cleaner parts
• Process a wide variety of materials

Why Engis?

• Engis is a micronizer – we purify, precision grade, disperse, and custom formulate our slurries.  We are unequaled in our ability to precisely characterize and control particle size distributions (PSD).
• Applications expertise – our engineers can provide the full process recommendation for your part/material – not only the best slurry formulation but also the polishing machine, lap plate or pad, accessories, and process settings.

Engis provides a broad range of diamond slurry formulations;

• Oil Based Slurries – Our S1313 is recognized as the workhorse slurry for a broad range of lapping applications.  It provides superior plate wetting and highly reflective finishes.

• Water Based Slurries – When part clean-up is a concern, water based slurries are widely used. Hyprez formulation S4889 is available in a wide range of abrasive sizes and offers superior results in finishing a myriad of materials.

• Emulsion Slurries – S841 is a good choice for final polishing steps. S841 maintains good particle dispersion of the diamond without settling for long periods of time. This slurry offers the benefits of oil while still being easy to clean.

• Suspensions – Our S4243 water based slurry requires no stirring to maintain abrasive particle dispersion. This high viscosity suspension is useful when using a polishing pad on double side applications where it is important to fully wet and cover the lap throughout the work cycle.
