Big Dog Adhesives BD5420 Epoxy Adhesive
- Chemical Family
- Epoxy & Epoxy Derivatives
BD5420 is a two-part, epoxy hybrid room temperature cure adhesive designed for bonding of metals, ceramics, and most plastics. It cures to a tough semi-rigid material, and is free flowing in viscosity. It gives good resistance to water, salt spray, inorganic acids and bases, and most organic solvents. It is especially formulated for a 2:1 mix ratio for use in side by side cartridges, or to be used by hand mixing, or use with meter mix equipment. A handling cure is normally achieved at room temperature within 120 minutes with a full cure at room temperature within 24 hours. To accelerate the final cure, or to quicken the handling simply elevate the temperature.
