What materials can HY925 bond with?
HY925 adheres well to metals, glass, concrete, stone, precast panels, various paints, and many other common construction substrates.
How does the product perform under extreme temperatures after curing?
Once cured, the sealant maintains excellent elasticity and stability. It does not become brittle, hard, or crack at temperatures as low as –30°C, and it does not soften or degrade at temperatures up to 200°C.
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.
What is the primary application of HY-723?
It is primarily used to control the spread of fire, smoke, and toxic fumes within areas surrounded by firewalls, such as construction joints and partitions.
