Re-Fine Bright 3-Minute Self-Hardening Plastic Powder (A2, 50g)

Title: YamaHachi Re-Fine Bright Self-Curing Acrylic Dental Plastic (A2, 50g)

English Description

YamaHachi Re-Fine Bright is a premium, self-curing (cold polymerization) high-strength acrylic dental plastic, perfect for a wide range of restorative procedures. This 50g powder (A2 shade) offers exceptional performance and ease of use. Its rapid 3-minute setting time minimizes chair-side time, while its superior properties ensure long-lasting, high-quality results.

Key Features and Benefits

• Fast Setting Time: Sets completely in approximately 3 minutes (at 23°C). Setting time may vary slightly with temperature fluctuations.
• High Strength & Durability: A unique blend of polymer particle sizes delivers exceptional strength and mechanical properties (flexural strength: 75 MPa).
• Excellent Workability: The powder/liquid mixture is easily manipulated, offering excellent modeling characteristics without excessive spreading. It also exhibits low adhesion to instruments, simplifying finishing and polishing.
• Color Stability: Maintains consistent color and translucency throughout the polymerization process.
• Versatile Applications: Ideal for:
  • Facing metal frameworks and clasps
  • Fabricating inlays, temporary crowns, and bridges
  • Indirect rebasing of removable dentures
  • Repairing and restoring removable dentures (base repairs, chipped acrylic teeth replacement)
  • Replacing missing teeth in denture bases
  • Creating orthodontic appliances
