HardmanDouble Bubble "Orange" Toughened Epoxy (Very High Peel Strength) 04007

Product Name

HardmanDouble Bubble "Orange" Toughened Epoxy (Very High Peel Strength) 04007

Brief Description

The Hardman Double Bubble "Orange" Toughened Epoxy 04007 is a two-component, semi-rigid, structural epoxy adhesive designed for demanding bonding applications. It cures at room temperature and is characterized by its very high peel and shear strengths, coupled with excellent resistance to shock, vibration, and impact. This formulation is flexible, tough, and durable, making it ideal for applications requiring resilience against dynamic loads and stress. The "Double Bubble" packaging provides convenient, pre-measured, single-use packets for easy mixing and application.

Special and Unique Features

• Very High Peel Strength: Provides superior resistance to forces that try to separate bonded surfaces by peeling.
• Toughened Formulation: Enhanced toughness and impact resistance compared to standard epoxies, allowing it to withstand impacts, mechanical stress, and dynamic loads without cracking.
• Vibration and Shock Resistant: Flexible and durable, making it suitable for applications subject to movement, vibration, and sudden impacts.
• Semi-Rigid Cure: Offers a balance of rigidity and flexibility, accommodating differences in thermal expansion between dissimilar substrates.
• Convenient Double Bubble Packaging: Pre-measured, single-use packets ensure accurate mixing ratios and minimize waste, making it easy for quick repairs and small jobs.
• No-Shrink Formula: Maintains bond integrity and prevents stress on bonded materials as it cures.
• No Solvents: Contains no solvents, contributing to a safer application environment and consistent performance.

Key Properties

• Type: Two-component, semi-rigid, structural epoxy adhesive.
• Curing Mechanism: Room temperature curing.
• Work Time: Approximately 3 hours.
• Handling Strength: Achieved in approximately 18 hours. (Full cure may take up to 7 days, but can be used after 24 hours in some applications).
• Adhesive Color (Cured): Gray. (The product is identified by its "Orange" package).

Surface Compatibility

This epoxy bonds effectively to a wide range of materials, including:

• Plastics: Polystyrene, ABS, nylon, PVC, and many other hard plastics.
• Metals: Carbon steel, stainless steel, aluminum, copper, brass, tin, zinc, and other metals.
• Wood: Various types of wood.
• Masonry: Concrete and other masonry materials.
• Rubber: Natural and synthetic rubbers.
• Glass: Glass and ceramic materials.
• Other: China, leather, stone, and composites.

Known backups / known substitutes

• Other Hardman Double Bubble Epoxies: Such as Hardman Double Bubble 04001 (Extra Fast Setting), 04005 (General Purpose), and 04008 (Non-Sag), which offer different cure times and properties.
• Toughened Epoxies from Other Manufacturers: Products from companies like 3M, Master Bond, EpoxySet, and Northern Composites that offer similar toughened epoxy formulations for high-performance bonding.
• Structural Acrylic Adhesives: While sometimes used in panel bonding, toughened epoxies like 04007 often offer advantages in shear strength, shelf life, temperature range, and solvent resistance.

Comparison Note

The Hardman Double Bubble "Orange" Toughened Epoxy 04007 distinguishes itself from conventional epoxies primarily through its "very high peel strength" and "toughened" characteristics. Unlike more brittle epoxies, its semi-rigid nature and enhanced ductility allow it to absorb and dissipate energy, providing superior resistance to shock, vibration, and impact. This makes it particularly well-suited for applications involving dynamic loads or dissimilar substrates with varying coefficients of thermal expansion, where traditional rigid adhesives might fail due to cracking or delamination. Its convenient "Double Bubble" packaging also offers a significant advantage for on-the-spot repairs and small-batch applications, ensuring precise mixing without the need for additional tools.
