2K PU SF
Primer
2K PU SF Primer is a high-performance two-component solvent-free polyurethane-urea primer developed for industrial protective coating applications on concrete, steel, and timber substrates. Its low-viscosity formulation penetrates deeply into porous surfaces, sealing and strengthening the substrate while creating a smooth, pinhole-free surface for subsequent coating systems. The moisture-tolerant formulation can be applied to slightly damp substrates, making it an excellent choice for industrial flooring, waterproofing, corrosion protection, and polyurea lining systems.
Available in 5L and 20L kit sizes.
