Product Data Sheet

Sikasil® N Plus US is a one-component, neutral-cure silicone sealant engineered for professional-grade sealing and bonding applications across construction, transportation, HVAC, marine, and industrial environments. Its non-sag, elastomeric RTV silicone formulation provides long-lasting flexibility, strong adhesion, and excellent weather resistance for both interior and exterior use.

Designed for versatility and ease of application, Sikasil® N Plus US bonds effectively to a wide range of substrates including glass, aluminum, tile, fiberglass, plastics, masonry, concrete, brick, wood, and painted surfaces. Its neutral-cure chemistry allows use on sensitive substrates without the corrosive effects associated with acetoxy-cure silicones.

The sealant offers outstanding UV resistance, weather stability, and long-term elasticity, making it ideal for applications exposed to moisture, sunlight, temperature changes, and dynamic joint movement. Its flexible silicone formulation helps absorb vibration, expansion, and contraction while maintaining durable sealing performance over time.

Sikasil® N Plus US is commonly used for window and door fabrication, glazing, perimeter sealing, HVAC systems, kitchen and bath installations, skylights, marine cabins, RVs, trucks, trailers, and appliance assembly applications. The product also contains fungicide additives to help resist mold and mildew growth in high-moisture environments.

Its ready-to-use formulation requires no mixing and can be applied using standard dispensing equipment for clean, efficient installation. Once cured, Sikasil® N Plus US forms a durable elastic seal capable of accommodating joint movement while delivering dependable long-term performance in demanding service environments.
