Megapoxy P1 Epoxy Paste Adhesive

Megapoxy P1 is a premium two-component epoxy paste adhesive formulated for high-performance bonding and gap-filling across a wide range of materials. Based on DGEBA epoxy resin and a carbonate-free filler, it offers ease of use with a simple 1:1 mixing ratio by volume and sets to provide excellent mechanical and chemical properties. Notably, Megapoxy P1 is volatile organic compounds free (Nil VOC), ensuring a safer working environment. It also meets the stringent requirements of AS/NZS 4020:2018 for products in contact with drinking water, making it ideal for potable water applications. Additionally, its resistance to hydrogen sulphide makes it suitable for use in sewage treatment plants and related infrastructure. With a work time of 60 minutes at 25°C, it allows ample time for application, and once fully cured, it exhibits superior strength characteristics, including a compressive strength of 80 MPa and a tensile strength of 45 MPa.

Primer Information: While Megapoxy P1 generally adheres well to properly prepared surfaces, using a primer can enhance adhesion on certain substrates. For porous concrete, a suitable epoxy primer can improve bond strength. For some smooth metals, light abrasion followed by degreasing is typically sufficient. Always refer to the surface preparation guidelines for specific recommendations.

Cure Time: The cure time for Megapoxy P1 is temperature-dependent. At 15°C, allow a minimum of 48 hours; at 25°C, 24 hours; and at 35°C, 12 hours. Full cure strength is achieved after 4 days at 25°C. Consider these times when planning projects in different Australian climates, as cooler temperatures will extend the curing period.

Coverage Rate: Coverage will vary depending on the application thickness and the nature of the surfaces being bonded or filled. As a gap-filling adhesive, the quantity needed will depend on the size of the gap. For steel reinforcement protection in concrete, a minimum 3mm layer is recommended to achieve equivalent protection to 50mm of concrete cover.

Application Temperature Range: The minimum application temperature for Megapoxy P1 is 10°C. Ensure that both the ambient and substrate temperatures are above this during application for optimal results. The maximum operating temperature of the cured adhesive is 80°C, suitable for a wide range of Australian conditions.

Chemical Properties: Megapoxy P1 is based on a DGEBA epoxy resin and carbonate-free filler. It is VOC-free and exhibits excellent chemical resistance, including resistance to hydrogen sulphide, making it durable in demanding environments like sewage treatment facilities. Its compliance with AS/NZS 4020:2018 confirms its suitability for contact with potable water.
