مانع التسرب باسف ماسترسيل (A+B) موديل (550J) الرمادي وزن (20KG)

Key specs include: two-component polyurethane, solvent-free, grey color, 20 kg package, high UV/weather resistance, chemical resistance to oils/fuels/Acids, strong adhesion to concrete/metal/wood/m masonry, suitable for interior and exterior use, flexible to accommodate substrate movement, and low-temperature compatibility down to -10°C with fast cure characteristics.

It adheres well to concrete, metal, wood, and masonry. For substrates outside this list, perform a compatibility test or consult the product data to ensure proper bonding and surface preparation.

Ideal for waterproofing and sealing expansion joints and other joints in construction projects, including balconies, roofs, basements, and bathrooms. It’s suitable for exterior and interior joints where movement is expected and robust chemical resistance is beneficial.

Prepare the substrate (clean, dry, and sound). Mix components A and B thoroughly until uniform. Apply using an appropriate sealant gun or dispensing method, then smooth or tool the sealant as required. Allow to cure under suitable conditions, keeping the area protected during curing. Follow all safety and handling guidelines during mixing and application.

The product is described as fast-curing. Exact cure and working times depend on temperature, humidity, substrate, and thickness of the applied joint. For precise timings, refer to the product technical data or data sheet.

Use appropriate PPE (eye protection, gloves, and ventilation). Avoid skin and eye contact and inhalation of any fumes. Store in a dry, well-ventilated area away from heat sources and ensure containers are kept closed when not in use. Dispose of packaging in accordance with local regulations.

It is formulated to offer UV resistance, weather resistance, and chemical resistance to oils, fuels, and acids, making it suitable for outdoor and harsh environments where exposure is a concern. Its bonding to common construction substrates and flexibility help maintain performance over time.

Yes, it is reported to be usable down to -10°C, which makes it suitable for use in cooler environments. Ensure surface preparation and application conditions meet the product’s guidelines for best results.
