Frequently Asked Questions
Find quick answers to the most common questions about our sealant products — from application tips to storage and performance details.
HY726
What surfaces and applications is HY-726 NOT recommended for?
While HY-726 is highly versatile, it is generally not recommended for the following:
Structural glazing applications where high-modulus, load-bearing sealants are required.
Surfaces that require paint application over the sealant, as silicone does not accept paint.
Porous natural stones such as marble or granite without proper testing, as silicone may cause staining.
Submerged or continuously immersed surfaces such as aquariums or swimming pools, unless specifically tested for such conditions.
Always conduct a compatibility test on a small, inconspicuous area before full application on any new or sensitive surface.
Is HY-726 mildew-resistant? Can it be used in bathrooms or kitchens?
Yes. HY-726 features excellent mildew-proof properties, making it a strong choice for high-moisture environments like bathrooms, kitchens, and shower glass installations. It resists the growth of mold and mildew over time, helping to maintain a clean and hygienic seal for longer periods compared to standard sealants.
Does HY-726 produce a strong or unpleasant odor during application?
No. HY-726 is formulated to be free of pungent odor. While a mild alcohol scent may be present during the curing process, it is significantly less offensive than acetoxy (acetic acid) silicones, which emit a strong vinegar-like smell. This makes HY-726 suitable for use in enclosed or poorly ventilated spaces.
HY-2300
Does HY-2300 contain strong odor or high VOC?
No. It features low VOC and low odour, making it safer for construction environments.
What is the temperature resistance after curing?
After full cure, it performs reliably in -50℃ to +150℃, maintaining elasticity and adhesion.
