Wessex 520 (UW 47 Primer) is a two-component, solvent-free epoxy primer developed specifically to optimise the performance of Wessex 4701 (UW 47) adhesive.
Specifically developed to maximise the bond strength and reliability of Wessex 4701 (UW 47) adhesive.
Two-component, solvent-free formulation for controlled application and reduced solvent-related risks.
Low-viscosity primer that enhances substrate wetting, preparation and adhesion, even in challenging conditions.
Designed for dry, controlled environments but suitable for certain underwater applications where improved penetration is required.
Designed for use in dry, controlled conditions, Wessex 520 ensures excellent substrate preparation and adhesion. Its low-viscosity formulation also allows it to be used in certain underwater applications where improved penetration and wet-out are required.
Part A is a white liquid epoxy resin, while Part B is a black liquid epoxy hardener containing a filler.
The Wessex 520 primer can be applied over a wide temperature range. Viscosity varies based on the working temperature. The recommended optimum application temperature range is 12°C to 25°C.
The Wessex 520 can be used in certain underwater applications where improved penetration and wet-out are required.
The Wessex 520 is a solvent free epoxy primer.
Yes, the Wessex 520 can be used for steel substrate materials.
The Wessex 4701 (UW 47 Adhesive) is a two-part, epoxy-based adhesive designed for exceptional performance in extreme environments and compatible with Wessex 520.
Formulated to cure at temperatures as low as 3 °C, it offers greater tolerance to oil and water contamination than most conventional epoxies. Ideal for bonding substrates that are fully immersed in fresh or seawater, delivering strong, reliable adhesion under conditions typically considered unsuitable for adhesives.
