1. CharacteristicsAcidic silicone sealant is a high-performance elastomeric sealant
primarily formulated for bonding and sealing applications across
construction, automotive, and household sectors, particularly
suitable for use with non-porous substrates such as glass,
aluminum, PVC, and other rigid plastics; it exhibits excellent
adhesion to these materials without the need for additional
primers, forming a tight and durable seal that effectively resists
moisture, air, dust, and common atmospheric pollutants, thus
providing reliable protection against water leakage and
environmental erosion; meanwhile, it boasts good flexibility and
elongation, enabling it to adapt to slight thermal expansion and
contraction or structural movements of the bonded substrates
without cracking or losing sealing performance, and it cures
quickly at room temperature to form a smooth, non-sticky surface,
ensuring efficient construction progress; additionally, it features
inherent resistance to UV radiation, ozone, and high/low
temperatures (typically ranging from -50℃ to 150℃), maintaining
stable performance in both harsh outdoor environments and indoor
conditions, making it a versatile and cost-effective sealing
solution for both professional and DIY projects. 2. Features- Fast room-temperature curing: Forms a usable seal within a short
time, significantly shortening the construction cycle.
- Strong adhesion: Delivers superior bonding strength to most
non-porous materials, ensuring long-term bonding stability.
- Excellent weather resistance: Resists UV rays, ozone, rain, and
extreme temperatures, with no obvious aging or degradation after
long-term outdoor use.
- Good flexibility: Offers high elongation rate (usually over 300%),
adapting to substrate deformation and preventing seal failure.
- Effective sealing performance: Densely fills gaps, blocking the
penetration of moisture, air, and dust, with excellent waterproof
and airtight effects.
- Easy to apply: Comes in a paste form that can be smoothly extruded
through a sealant gun, suitable for gaps of various shapes and
sizes.
- Corrosion-free for non-porous materials: Does not cause corrosion
or discoloration to glass, aluminum, and most plastics during use.
3. Applications- Construction industry: Sealing and bonding of glass curtain walls,
window and door glass installation (especially aluminum alloy
windows and PVC windows), sealing of glass partitions, bathroom
glass enclosures, and expansion joints of ceramic tiles in kitchens
and bathrooms; also used for sealing gaps between building exterior
walls and decorative panels.
- Automotive industry: Sealing of automotive glass (front and rear
windshields, side windows), sealing of sunroofs, bonding and
sealing of automotive interior and exterior trim parts, and sealing
of gaps in automotive lamp assemblies.
- Household and daily use: Sealing of kitchen appliances (such as gas
stoves, ovens, and refrigerators) to prevent oil and water
penetration; bonding and sealing of aquariums, fish tanks, and
decorative glass crafts; sealing of gaps around air conditioners,
water heaters, and other household appliances.
- Electronic and electrical industry: Sealing of small electronic
components, sensors, and electrical enclosures to provide
moisture-proof and dust-proof protection, ensuring the stable
operation of equipment.
- Industrial manufacturing: Sealing and bonding of plastic products,
aluminum alloy parts, and glass components in equipment production,
such as sealing of mechanical casings and bonding of industrial
pipelines (for non-corrosive media).
