Loncool sealant construction is a one-component, neutral-cure silicone sealant designed for weatherproofing various curtain walls. It cures at room temperature by absorbing moisture from the air, forming a flexible, strong silicone elastomer with excellent migration resistance and excellent resistance to high and low temperatures and UV rays.
Applications
It offers excellent adhesion and flexibility, adapting to dimensional changes between the curtain wall and the underlying structure caused by environmental fluctuations such as high and low temperatures, wind loads, and seismic loads. It is the preferred material for building curtain walls, ensuring the safe and durable use of building curtain walls and the challenges of complex external climates.
Features
- Long-lasting sealing protection, elasticity, and low shrinkage.
- Withstands a wide range of temperature conditions, ensuring weatherproofing.
- Insulation capabilities, and the use of fire-resistant sealants, where necessary, to isolate different spaces from smoke and toxic gases.
- A variety of color additives for enhanced aesthetics.
- Non-toxic substances ensure end-user safety.
Benefits
Easy to Use
Suitable for all temperatures, this construction silicone sealant is ready to use immediately.
Primer-Free Bonding
After curing, it adheres securely to most common building components without the need for a primer.
Long-Term Reliability
The cured sealant remains flexible at temperatures between -50°C and 150°C and will not harden, crack, or become brittle under normal weather conditions.
Low Modulus
Tensile / Compressive Strengths can reach ±50% of the original joint width.
Excellent Weather Resistance
Virtually unaffected by sunlight, rain, snow, and ozone.
Strong Mechanical Properties
Enable secure adhesion to a variety of surfaces, including concrete, stone, and brick.
