Frequently Asked Questions
What does "two-component" mean for this sealant product?
A two-component product consists of two separate parts — Component A and Component B — that must be mixed together before application. For this product, A and B are combined in a volume ratio of 10:1 to initiate the curing process and achieve optimal performance.
What is neutral curing and why does it matter?
Neutral curing means the product releases no acidic or alkaline by-products during the curing process. This makes it safe for use on sensitive substrates such as natural stone, marble, metals, and coated glass, as it will not cause staining or corrosion.
How does this product perform in extreme weather conditions?
This product offers excellent weather resistance, including resistance to high and low temperatures, ozone, and UV radiation. This ensures long-term durability and performance even when exposed to harsh outdoor environments, direct sunlight, or significant temperature fluctuations.
What building materials is this product compatible with?
This product has good adhesion to most common building materials, including concrete, masonry, glass, aluminum, and various coated surfaces. Its elasticity ensures the bond remains effective even when substrates undergo movement or thermal expansion.
What does a displacement capacity of ± 20% mean in practice?
A displacement capacity of ± 20% means the sealant can accommodate joint movement — both expansion and contraction — of up to 20% of the original joint width without cracking or losing adhesion. This is critical for joints that experience regular movement due to thermal changes or structural loads.
Is this product suitable for both indoor and outdoor applications?
Yes. Thanks to its UV resistance, ozone resistance, and broad temperature tolerance, this product is well-suited for both indoor and outdoor applications. Its high modulus formula and strong adhesion to building materials make it a reliable choice for construction joints, curtain walls, and facade sealing projects.
