Parasilico Alcoxy 15 Neutral Curing Silicone Sealant

Size: 300ml

Parasilico Alcoxy 15 Neutral Curing Silicone Sealant (300ml) is a premium-grade, single-component, neutral alcoxy curing silicone designed for demanding professional use in construction and glazing. Its advanced formulation delivers outstanding performance across a wide variety of substrates, including glass, metal, masonry, ceramics, and plastics, without the need for primers in most cases.

This sealant offers excellent adhesion and long-term elasticity, ensuring a flexible yet durable seal that can withstand structural movement, making it ideal for expansion joints, perimeter sealing around windows and doors, curtain walls, and facade elements. The neutral cure system ensures non-corrosive behavior, making it safe for use on sensitive materials like mirrors, natural stone, and metals prone to oxidation.

With a low modulus and excellent recovery characteristics, Parasilico Alcoxy 15 is well-suited for both interior and exterior applications. It demonstrates superior resistance to UV radiation, ozone, weathering, and extreme temperatures, making it a reliable choice for long-term sealing in varied environments.

Further benefits include:

• Low VOC emissions (EC1 Plus certified) – safe for indoor environments and environmentally conscious projects

• Fast skin-over time – reduces dust and contamination risk during application

• Easy application – compatible with standard caulking guns and performs well even at low temperatures

• Non-yellowing and color-stable over time

Ideal for:

• Glazing and glass-to-frame sealing

• Expansion joints in precast concrete

• Sealing of curtain walls and cladding

• Window and door perimeter sealing

• Sanitary and façade applications

Whether for commercial, residential, or industrial projects, Parasilico Alcoxy 15 delivers professional-grade performance and lasting reliability in a convenient 300ml cartridge.
