Prestige by Certus Optima Investment-49 lb Bag

Prestige Optima by Certus is a next-generation, gypsum-bonded investment engineered to deliver ultra-smooth cast surfaces when working with today's challenging pattern materials—especially resin (DLP/SLA). Its extra-high expansion is designed to accommodate high-expanding patterns, helping to minimize flashing and mold cracking while improving detail and metal flow.

Features

• Formulated for resin patterns; also excellent with carving waxes, injection waxes, plastics, and wax-based polymers
• Very high mold expansion supports clean burnout and accurate fit
• Easy, forgiving mix to a creamy, pourable slurry with low rise under vacuum
• Outstanding temperature resistance for higher burnout schedules
• Helps reduce porosity in difficult alloys and captures fine detail
• Suitable for high-temperature alloys including palladium white gold

Specifications
