3M Scotchbond Multi-Purpose Primer 3008

Clinical Overview

3M™ Scotchbond™ Multi-Purpose Primer is a light-cured, total-etch dental primer designed to condition dentin and enamel surfaces prior to adhesive application. As a key component of the Scotchbond™ Multi-Purpose system, it enhances surface wetting and promotes optimal penetration of the adhesive into tooth structure. The result is a strong, reliable hybrid layer that supports durable bonding and long-term restorative success.

Key Benefits

• Enhanced surface wetting: Improves adhesive penetration into etched dentin and enamel for stronger bonding.
• Reliable bond strength: Supports consistent adhesion across a wide range of restorative materials.
• Performs in challenging conditions: Effective on both moist and dry dentin, including sclerotic surfaces.
• Reduces microleakage: Helps minimize marginal gaps and post-operative sensitivity.
• Part of a proven system: Integrates seamlessly with Scotchbond™ Multi-Purpose Adhesive for predictable results.
• Easy application: Low-viscosity formula allows quick, uniform coverage of prepared surfaces.
• Versatile clinical use: Suitable for both direct and indirect restorative workflows.

Kit Contents

• 1 × 8 mL bottle of 3M™ Scotchbond™ Multi-Purpose Primer

Working & Setting Times

• Working: Apply immediately after etching while dentin remains slightly moist.
• Setting: Gently air-dry; no light curing required before adhesive application.

Indications

• Conditioning dentin and enamel in total-etch bonding procedures
• Direct composite and compomer restorations
• Indirect restorations including veneers, inlays, and onlays
• Porcelain, ceramic, and composite repair procedures
• Bonding composite to dentin and enamel surfaces

Instructions for Use

1. Etch enamel and dentin with phosphoric acid, then rinse thoroughly.
2. Gently air-dry, leaving dentin slightly moist (do not overdry).
3. Apply primer evenly to the prepared surfaces.
4. Gently air-dry to allow penetration and evaporation of solvent.
5. Do not rinse; proceed directly with adhesive application.
6. Continue with restorative procedure as indicated.

Summary

3M™ Scotchbond™ Multi-Purpose Primer (3008) is a critical step in achieving strong, durable adhesion in total-etch systems. By optimizing surface conditioning and enhancing adhesive penetration, it ensures predictable bonding performance across a wide range of clinical situations, making it an essential component for high-quality restorative dentistry.
