Low Viscosity, polyurethane based primer / concrete sealer, for both porous & non-porous substrates, and both dry & wet concrete.
HyperCoat SB Primer is a one component, low viscosity, polyurethane based primer suitable for many different substrates.
It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different substrates, whether of high, low or no porosity (e.g. glass and metals). Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate. The cured film displays outstanding mechanical properties: Its elongation is 300%, and its tensile strength surpasses 30 N/mm2. Apply with brush or roller.
Consumption: 100- 200gr/m2, subject to substrate porosity.
Compliance: The adhesion strength of HyperCoat SB Primer exceeds the requirements of 3456 (European Organization of Technical Approval).
Recommended for: To be used as primer for:
• Concrete structures (Humid, damp or wet concrete)
• Ceramic tiles
• Non-porous substrates like glass, marble & metals.
Bitumen ,
EPDM & TPO membranes Also, for use as concrete sealer.
Limitations:
Will discolour when used on its own exposed. This is purely visual and does not affect the performance of the membrane.
Application Procedure:
Clean the surface using a high pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes must also be removed. If there are surface irregularities, we recommend charging HyperCoat SB Primer with sand.
Apply with brush or roller. Once cured, the main membrane can be applied.
Recommendation: Always make a test coat to ensure the compatability of product and surface.
Packaging: 1 Lt, 5 Lt, 20 Lt.
Shelf Life: Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25oC. Once opened, use as soon as possible. Safety Information: Contains volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. In closed spaces use ventilators and carbon active masks. Keep in mind that solvents are heavier than air so they creep on the floor.
The MSDS (Material Safety Data Sheet) is available on request.
