POLEPOX-PU PRIMER 100
POLEPOX-PU PRIMER 100 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 that 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.
RECOMMENDED FOR
To be used as primer for:
- Concrete structures (humid, damp or wet concrete).
- Ceramic tiles.
- Non-porous substrates like glass, marble & metals.
- 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.
- If the concrete is very porous, the material may penetrate to a degree that no film is created on the surface. In this case, there will be need for subsequent coating in order to create the dust-free primed surface.
FEATURES & BENEFITS
- One component.
- Of low viscosity.
- Easily applicable, even on wet concrete.
- Adheres strongly, even on glassy, non-porous substrates.
- Excellent wetting, impregnation and paint-over time.
- Elastic.
- Many pigment pastes available.
- A low-cost solution for concrete sealing & protection.
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.
CLEANING
Clean tools and equipment first with paper and then using cellulosic or polyurethane thinner. Rollers will not be re-usable.
PACKAGING & SHELF LIFE
- Packaging: 20 KG.
- Shelf Life: Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25 °C. 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.
