    MasterSeal NP 430 - High performance, UV resistant, highly elastic modified silicone joint sealant

    How does MasterSeal NP 430 work?

    MasterSeal NP 430 is a one component, moisture curing, thixotropic modified silicone sealant.

    MasterSeal NP 430 is recommended for active, exterior and interior joints that demand extreme UV resistance and long term colour integrity including but not limited to: expansion joints in buildings and civil structures above and below ground, construction joints, joints in precast concrete elements, external walling and cladding joints, infill panel joints, curtain walling, etc.

    What are the unique features of MasterSeal NP 430?

    Modified silicone (MS) technology ensures MasterSeal NP 430 is UV resistant, non-chalking, non-staining, and self-cleaning, resulting in unmatched durability.

    What are the benefits of MasterSeal NP 430?

    • UV stable MS technology - non-staining, non-yellowing, non-chalking, low dirt pickup, self-cleaning
    • Low modulus - excellent puncture and abrasion resistance
    • Iproved gunability and workability over polyurethane sealants - easy gunning and tooling
    • Movement capability +/-25% - expands and contracts with joint movement
    • Excellent chemical resistance - ideal in food Preparation or chemical contact environments
    • Paintable –allows common acrylic paints to stick and to give the building an aesthetic appearance
    • Accelerated skinning and curing – achieves cure faster than polyurethanes and skins quickly reducing dirt pick on the wet sealant
