Use Megapoxy 69 for: Bonding metals, concrete, timber, and stone with a high-strength, non-sag epoxy adhesive.
Megapoxy 69 is a translucent, non-sag gel type epoxy structural adhesive designed for high-strength bonding in various applications. Its unique non-sag consistency makes it ideal for vertical and overhead applications, while its robust tensile bond strength to steel (30 MPa) and tensile shear strength (>20 MPa) ensure reliable structural integrity. This versatile adhesive is perfect for bonding metals to metals, metals to concrete and masonry, assembling granite and marble fabrications, and structural timber joinery. It also excels in marine environments, maintaining its high strength even after repeated impact forces. With a long work time of 45 minutes at 25°C, Megapoxy 69 allows for precise application and adjustments, minimizing waste and maximizing efficiency. Its VOC-free formulation prioritizes applicator safety and environmental responsibility.
Primer Information: Surface preparation is critical for optimal adhesion. Concrete should be free from grease and laitance, requiring mechanical abrasion or acid etching. Metal surfaces should be grit blasted to AS CK 9.4 standards. Coated surfaces should be removed.
Cure Time: Cure times vary with temperature: 12 hours at 35°C, 24 hours at 25°C, and 48 hours at 15°C. Ensure proper curing before subjecting bonded materials to stress. At 25 degrees, the working time is 45 minutes.
Coverage Rate: Coverage depends on application thickness and surface area. The non-sag gel consistency allows for controlled application, minimizing waste.
Application Temperature Range: Apply between 10°C and 35°C for optimal results. Ensure substrate temperatures are within this range during application and curing.
Chemical Properties: This epoxy adhesive offers excellent chemical resistance and does not shrink upon curing. Its VOC-free formulation ensures compliance with Australian safety standards.
