Resiflex Hybrid Polyurethane Sealant

Duram Resiflex Hybrid typically adheres tenaciously to common construction substrates without primers. However, Duram always recommends that a field adhesion test be performed on the actual materials being used on the job to verify the need for a primer. If a primer is needed, use the following:

• For Porous Substrates: Duram Primeseal MC
• For Non Porous Substrates: Duram Super prime 711
• For Metal Surfaces: Duram ME Primer

Resiflex Hybrid Polyurethane Sealant

Resiflex Hybrid is a high-performance, low modulus, single-component moisture-cure polyurethane hybrid sealant engineered for superior sealing in façade and window perimeter applications. Leveraging proprietary polymer technology, this sealant provides a fast cure time and is paintable, making it a versatile choice for various sealing needs. Ideal for sealing and waterproofing control joints, precast concrete panel joints, gaps, corners (fillets), penetrations, and cracks, Resiflex Hybrid excels in bonding plastic and metal angles to concrete, timber, and FC sheeting substrates. Its formulation ensures excellent adhesion, flexibility, and compatibility with Duram Water Based Waterproofing Membranes.

Key features

Key features include its fast curing time, ease of use, and the fact that it is both isocyanate and silicone-free. The sealant has a typical skin time of 45 minutes and cures at a rate of 2.5mm per day. It is suitable for a wide temperature range, from -40°C to 90°C, and offers impressive elongation of 500%, ensuring it can handle significant movement without failure. Resiflex Hybrid is available in 600ml sausages, packed 20 per carton, and is provided in a standard grey color. It has a shelf life of up to 12 months when stored in a dry, cool place in its original, unopened packaging.
