Heavy Duty Non-Sag Anchoring and Doweling Epoxy for Threaded Rod and Rebar in Uncracked Concrete
ULTRABOND® 1300 is a high strength doweling epoxy designed for concrete construction and structural applications. This adhesive delivers reliable performance when installing threaded rods, rebar dowels, and other anchoring systems into concrete. Developed by Adhesives Technology, this epoxy system supports demanding building construction and infrastructure projects where strength and consistency are critical.
This high strength doweling epoxy features a smooth, non-sag, non-abrasive consistency. It performs well in horizontal applications and overhead installations, allowing for accurate placement without slumping or material loss. Its concrete gray finish blends well with surrounding substrates, making it suitable for visible and structural applications alike.
High Strength Doweling for Structural Applications
ULTRABOND® 1300 provides high strength anchoring for a wide range of applications. It bonds securely to concrete and steel, including stainless steel, ensuring long term performance under load. This concrete dowel epoxy is ideal for:
Adhering dowel bars and tie bars
Installing rebar dowels into existing concrete
Structural anchoring in infrastructure and commercial builds
Heavy duty anchoring in industrial environments
Its high modulus epoxy formulation ensures strong load transfer and stability. Contractors rely on this strength anchoring epoxy for both new installations and retrofit work when they cannot compromise performance.
Moisture Insensitive Performance
ULTRABOND® 1300 is moisture insensitive, allowing installation in damp or wet environments. This makes it suitable for job sites where conditions may vary or where curing must take place in less controlled environments.
The ability to install dowels in damp concrete helps reduce downtime and keeps projects moving across all working days. This reliability is especially important in infrastructure and construction schedules where delays can impact timelines.
Controlled Working Time and Cure Time
This epoxy system offers a practical working time of approximately 16 minutes at 75°F (24°C). This gives installers enough time to position anchors accurately before the material begins to set. Depending on site conditions, working time may vary slightly, typically ranging between 5 and 20 minutes.
The cure time depends on temperature and environmental conditions, but the system builds strength steadily after placement. This predictable curing timeline helps contractors plan installation schedules. It also helps them manage rest periods. It keeps on-site work efficient.
Optimised for Bulk Dispensing Systems
ULTRABOND® 1300 is available in both cartridge and bulk dispensing formats. Its non-abrasive formulation ensures compatibility with bulk dispensing equipment without causing excessive wear on pumps or components.
This makes it ideal for high volume applications where consistent output is required. The smooth flow supports efficient application and reduces maintenance needs for dispensing systems.
Compliance and Approvals
ULTRABOND® 1300 meets ASTM C881-20 / AASHTO M235 Type I, II, IV & V Grade 3 Class B & C standards and holds extensive DOT approvals. These certifications confirm its suitability for regulated construction and infrastructure applications where safety and compliance are essential.
Available Packaging Options
ULTRABOND® 1300 comes in many cartridge and bulk kit sizes. These options fit different project needs, from small installs to large construction jobs. Options include:
8.6 fl. oz. cartridge
21.2 fl. oz. cartridge
53 fl. oz. cartridge
