ResDev Pumaprime ESD

Pumaprime ESD is a two-component solvent-free conductive primer based on waterborne epoxy technology. Suitable for use within a ResDev Electro Static Dissipative Floor System.

Best Uses

ResDev Pumaprime ESD is used as a conductive primer for anti-static and electrostatic dissipative systems such as ResDev Pumadur HF ESD, ResDev Pumadur SL ESD and ResDev Pumaflow ESD.

Benefits from being low viscosity / easy to mix and apply, high solids and has a long pot-life.

Application

Inadequate preparation will lead to loss of adhesion and failure. In coatings and flow applied systems there is a tendency for the finish to mirror imperfections in the substrate. Grinding, or light vacuum-contained shot-blasting is therefore preferred over planing for these systems. Percussive scabbling or acid etching is not recommended. Pumaprime ESD is a two-component product. Fully drain the contents of the hardener component into the resin component and mix thoroughly with a low speed electric mixer (300 - 400 rpm) for a minimum of 3 minutes scraping sides and bottom of container until homogeneous. Pour the material into a fresh container and mix for a further minute.

Pumaprime ESD must be applied to surfaces pre-primed with ResDev Pumaprime SF which has been allowed to cure. Apply evenly using a medium pile roller or brush. Do not exceed the coverage rate of 4m2 per kg. Do not pour directly onto the substrate as this may result in thick patches. Use a 1” paintbrush to work material into earthing and bridging points ensuring good contact. When cured, the resistance to earth as measured by the chosen test method should be 5 x 104 ohms or less. This test must be carried out and logged. If, when cured, there are glossy or bare patches, a further primer coat is required. Allow to cure for a minimum 12 hours at 20°C. If the primer has been left to cure for >48 hours then the primer surface should be mechanically abraded and the area re-primed.

It is recommended that each individual slab is either connected to each other by bridging or each individual slab be directed to earth. The use of copper tape is recommended for this purpose. As a general rule, apply copper tape at maximum 4 metre centres ensuring that no part of the floor is more than 2 metres away from copper tape.
