Astral Bondtite Pro: The Advanced Industrial-Grade Epoxy Adhesive
For demanding structural applications where standard glues fail, Astral Bondtite Pro (Advanced Epoxy) is the professional choice. This is a high-performance, two-component (2K) epoxy adhesive engineered to provide unparalleled bonding strength, chemical resistance, and durability. Unlike fast-setting household epoxies, Bondtite Pro is formulated with advanced polymers for a slower cure, resulting in a stronger, more resilient bond capable of withstanding heavy loads and harsh environments.
Astral Bondtite Pro is universally compatible, offering permanent adhesion to virtually all materials, including hard-to-bond metals, plastics, wood, and concrete. It is the go-to solution for engineering, automotive, and heavy-duty structural repairs.
Why Choose Astral Bondtite Pro?
Its slow cure and specialized formula provide superior performance for structural applications:
- Industrial Strength: Provides tensile strength far superior to standard adhesives, making it ideal for load-bearing and vibrating components.
- High Chemical Resistance: Once cured, it is highly resistant to fuels, oils, solvents, and water, perfect for automotive or marine applications.
- Excellent Gap Filling: Its consistency allows it to fill uneven gaps between substrates, ensuring 100% surface contact and bond integrity.
- Versatile Compatibility: Bonds metals, wood, stone, ceramic, fiberglass, and most hard plastics (excluding PP/PE).
Key Features of Astral Bondtite Pro
- Two-Component Epoxy (2K): Ensures a strong, permanent chemical cross-link when mixed 1:1.
- Long Working Time: Provides ample time to position parts accurately and complete complex assemblies.
- Non-Shrinking: Cures without shrinking or cracking, maintaining its volume and stability in the joint.
- Machinable Cure: Can be drilled, sanded, tapped, and painted, making the repair virtually invisible.
Recommended Application Areas
This advanced epoxy adhesive is essential for:
- Automotive Repairs: Bonding metal parts, repairing cracked engine blocks, or fixing heavy plastic bumpers.
- Marine/Industrial: Securing fittings on boats, repairing industrial equipment, and assembling machinery components.
- Home Repairs: Structurally bonding wood joints, fixing broken tools, and restoring cracked marble or stone.
- General Repairs: Permanent, high-strength bonding of metal to wood or concrete.

How to Use Astral Bondtite Pro
- Preparation: Surfaces must be clean, dry, and free of oil or grease. For optimal strength, roughen smooth surfaces (like metal) with sandpaper.
- Mixing: Dispense equal amounts of Resin and Hardener onto a clean, disposable surface. Mix thoroughly with a spatula until the color is uniform (typically transparent or pale yellow).
- Application: Apply the mixed adhesive to both surfaces. Clamp or secure the parts together immediately and hold them in place for at least 4 hours. Do not move or stress the joint during this time.
- Curing: Allow a full 24 hours for the repair to reach maximum structural strength. Learn more about proper epoxy application and curing.
Frequently Asked Questions (FAQ)
Q: Why does Bondtite Pro take longer to set than other epoxies?
A: The longer set time allows the polymer chains to form longer, stronger cross-links, which results in superior ultimate strength and chemical resistance compared to 5-minute epoxies.
Q: Can I use this for filling large gaps?
A: Yes, its high viscosity is excellent for filling gaps. For vertical gaps over 5mm, mixing in a filler powder (like fumed silica) can prevent sagging.
Q: Can it be used outdoors?
A: Yes, once fully cured, it is highly weather and moisture resistant, making it suitable for protected exterior applications.
