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 is HY-726 Premium Clear Neutral Silicone Sealant, and what makes it different from regular silicone sealants?
HY-726 is a one-component, 100% silicone, alcohol-based elastomeric adhesive sealant. Unlike regular silicone sealants, it is specifically formulated as a neutral cure product, meaning it releases alcohol instead of acetic acid during curing. This makes it completely non-corrosive, non-toxic, and safe for use on sensitive surfaces such as copper, gold, and metal-coated mirrors — surfaces that standard acidic silicones would permanently damage.
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.
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.
HY-2300
What is HY-2300 mainly used for?
HY-2300 is designed for outdoor glazing and weatherproof sealing, especially suitable for curtain wall joints, window & door frames, ACP panel seams, and general building decoration sealing.
What is the product standard?
HY-2300 meets JC/T882-2018, grade 125HM performance test standard.
