Buying advice

When choosing an adhesive primer, match the primer chemistry to both the adhesive and the substrate. Metal surfaces generally benefit from primers formulated for epoxy or acrylic systems, while plastics need low-viscosity, non-corrosive primers. Consider cure time, temperature resistance, and whether the primer is compatible with the specific adhesive you plan to use. Budget-focused projects can use cost-effective options like Loctite 770 Primer, but for high-temperature or demanding applications, heat-resistant primers such as Permabond 910 provide more reliable performance.
