Product Selection
To guarantee maximum processing efficiency and reduce machine downtime, selecting the right chemical grade for your specific glass application is crucial:
1. MORESCO TOOLMATE GR-5 (Edging Specialty):
Your primary choice for automotive and architectural glass edging. Its core technical mechanism forces glass dust to deposit quickly instead of hardening into dense cakes, allowing filters and centrifugal systems to clear the tank effortlessly.
2. MORESCO TOOLMATE GR-4 (Precision & Lens Specialty):
If your manufacturing involves Curve Generator (C.G.) processing, centerless grinding, or precision surface grinding for optical glass lenses and technical ceramics, MORESCO GR-4 is recommended to maintain optimal particle washing and prevent micro-scratches.
