Frequently Asked Questions
Q
What does "two-component" mean for this sealant product?
A two-component product consists of two separate parts — Component A (base) and Component B (curing agent) — that must be mixed together before application. For this product, the mixing ratio is 10:1 by volume, which activates the curing process and ensures optimal performance.
Q
Why is neutral curing important for building applications?
Neutral curing sealants release non-corrosive byproducts during curing, making them safe to use on sensitive substrates such as natural stone, marble, concrete, and metals. They do not cause staining or corrosion, which is critical for long-term building integrity.
Q
What level of UV and weather resistance does this product provide?
This product offers excellent weather resistance, including resistance to high and low temperatures, ozone exposure, and ultraviolet (UV) radiation. This ensures that the sealant maintains its flexibility, adhesion, and appearance even after prolonged outdoor exposure.
Q
Which building materials is this sealant compatible with?
This sealant exhibits good adhesion to most common building materials, including glass, aluminum, concrete, ceramic tiles, and coated metals. Its elasticity allows it to maintain a strong bond even when substrates expand, contract, or experience minor movement.
Q
What does a displacement capacity of ±20% mean in practice?
A displacement capacity of ±20% means the sealant can accommodate joint movement of up to 20% of the original joint width — both in expansion and compression — without cracking or losing adhesion. This makes it suitable for joints that experience regular thermal or structural movement.
Q
How should the A and B components be mixed correctly?
The A and B components should be mixed in a 10:1 volume ratio using a mechanical mixer or a dual-cartridge dispensing gun to ensure a uniform and consistent blend. Improper mixing ratios may result in incomplete curing, reduced adhesion, or compromised mechanical performance.
