Neutral silicone sealant is a high-performance, one-component, neutral-curing colloidal material that boasts a wide range of application
scenarios and outstanding comprehensive advantages, making it an indispensable sealing and bonding material in various industries. It is
extensively used in both indoor and outdoor settings, covering building decoration (such as door and window installation, curtain wall sealing, and
interior gap filling), industrial manufacturing (including electronic component fixing, automobile part sealing, and chemical container sealing),
sanitary ware installation (bathtubs, sinks, and bathroom fixtures), as well as daily DIY projects and professional construction. During the curing
process, this sealant is almost odorless and does not release any acidic or corrosive substances, which makes it highly safe to use on a variety of
sensitive surfaces—such as metals (aluminum, steel, copper), natural stone (marble, granite), delicate plastics, and glass—without causing
discoloration, corrosion, or damage. Additionally, it exhibits excellent adhesion to most common substrates, eliminating the need for primers in
most cases, ensuring firm and long-lasting bonding even in humid or harsh environments. Its outstanding temperature resistance allows it to
maintain stable performance in an extremely wide temperature range from -60°C to 250°C, making it suitable for both low-temperature outdoor
environments and high-temperature industrial scenarios. Moreover, it possesses superior weather resistance, capable of withstanding long-term
UV radiation, heavy rain, strong winds, and extreme temperature changes without aging, cracking, or losing elasticity. With good elasticity and
excellent waterproof, dustproof, and sound-insulating properties, it can effectively seal gaps of different sizes, prevent air, moisture, and dust
penetration, and adapt to slight structural deformations caused by temperature changes or external forces. Whether in high-humidity spaces like
bathrooms and kitchens, harsh outdoor construction sites, or precision industrial equipment, neutral silicone sealant maintains consistent and
reliable performance, earning it a reputation as a versatile, durable, and user-friendly sealing material for both professional and daily use.
Features
Neutral curing: Does not release acidic or corrosive substances, safe to use on sensitive surfaces such as metals, natural stone and delicate plastics without causing damage or discoloration.
Excellent adhesion: Bonds firmly to most common substrates including glass, ceramics, aluminum, steel, wood, concrete and various plastics, with good adhesion integrity even in long-term use.
Superior durability: Has excellent weather resistance, UV resistance and chemical corrosion resistance, not easy to age, crack or lose elasticity, ensuring long-term sealing effect in indoor and outdoor environments.
Good flexibility and non-shrinkage: Maintains high flexibility after curing, can adapt to joint movement caused by temperature changes or structural deformation, and has low volume shrinkage during vulcanization to ensure tight sealing without gaps.
Environmental friendliness and safety: Low odor, solvent-free, no harmful volatiles after curing, non-toxic and environmentally friendly, suitable for indoor environments with high environmental requirements and even partial medical device applications.
Easy construction: Ready to use, can be easily extruded and tooled at temperatures between 5°C and 50°C, with a reasonable skin formation time and curing speed, suitable for both professional construction and DIY operations.
Applications
Building industry: Sealing of door and window frames and glass gaps to achieve heat insulation, sound insulation and waterproof effects; sealing of indoor and outdoor curtain walls (such as glass curtain walls, stone curtain walls) to adapt to structural deformation; filling and sealing of gaps in interior decoration, including tile joints, metal decorative strips, lamps and other installations; sealing of expansion joints in concrete, pavements and industrial floors.
Sanitary and kitchen areas: Sealing around bathtubs, showers, sinks, vanities and mirrors in bathrooms; waterproof sealing between kitchen countertops, splashbacks and tiles, with mold and mildew resistant properties to adapt to high-humidity environments.
Industrial field: Sealing and fixing of electronic components and circuit boards, providing insulation and protection against dust and moisture; sealing of automobile body gaps and interior parts to enhance sound insulation and durability; sealing of chemical containers to prevent leakage of chemical substances due to its good chemical corrosion resistance.
Other fields: Sealing of aquariums due to its non-toxic and waterproof properties; bonding and sealing of small crafts and DIY projects; sealing of medical device casings to ensure sterility and cleanliness; sealing of glass display cabinets, cable ducts and other equipment.
