1. CharacteristicsAcidic silicone sealant is a one-component elastomeric adhesive and
sealant formulated with silicone polymers, which exhibits excellent
adhesion to a wide range of common construction materials such as
glass, aluminum, ceramic tiles, and most rigid plastics; it cures
at room temperature through a chemical reaction with atmospheric
moisture, gradually transforming from a paste-like consistency into
a flexible, rubbery solid that maintains its integrity across a
broad temperature spectrum, typically from -40°C to 150°C. This
type of sealant is widely utilized in both residential and
commercial construction scenarios, including sealing the gaps
between glass and window frames, bonding kitchen and bathroom
fixtures to ceramic surfaces, and sealing joints in decorative
glass installations; its application involves a straightforward
process: first, the target surface must be thoroughly cleaned to
remove dust, oil, grease, and any other contaminants that might
compromise adhesion, then the sealant is extruded evenly from a
cartridge using a caulking gun, ensuring full contact with both
sides of the joint or gap, and finally, the applied sealant is
smoothed with a tool (or a gloved finger) to achieve a neat finish
and promote optimal bonding, with a full cure usually completed
within 24 to 72 hours depending on environmental conditions like
temperature and humidity. 2. Features- Strong Adhesion Performance: It forms reliable and long-lasting bonds with various non-porous
and semi-porous materials without the need for additional primers,
reducing construction complexity.
- Excellent Weather Resistance: After curing, it can effectively resist ultraviolet radiation,
rain, snow, and temperature fluctuations, maintaining its sealing
and bonding properties without cracking or aging for a long time
outdoors.
- Good Elasticity: It retains excellent flexibility even after full curing, which
can adapt to the thermal expansion and contraction of building
materials or slight structural displacements, preventing the seal
from failing due to material movement.
- Fast Surface Curing: Under normal temperature and humidity conditions, its surface can
cure quickly (usually within a few hours), reducing the risk of
contamination during the construction process and shortening the
subsequent construction cycle.
- Waterproof and Mildew-Proof: It has excellent water impermeability, which can effectively
block the penetration of water; in humid environments such as
kitchens and bathrooms, it also has a certain mildew-proof ability,
keeping the sealed area clean and hygienic.
3. Applications- Architectural Glazing: Used for sealing the gaps between glass panels and aluminum
profiles in curtain walls, glass doors, and windows, ensuring
waterproofing and windproofing while enhancing the overall
structural integrity.
- Residential Interior Decoration: Applied in kitchen and bathroom renovations, such as sealing the
joints between sinks and countertops, bathtubs and walls, and
toilet bases and floors, preventing water leakage and mildew
growth.
- Decoration and Bonding: Used for bonding and sealing decorative materials like glass
mosaics, mirrors, and decorative panels, providing both aesthetic
appeal and structural stability.
- Electrical and Electronic Sealing: Suitable for sealing the casings of small electrical appliances
(such as refrigerators, air conditioners) and the gaps of
electronic component enclosures, playing a role in dustproof,
waterproof, and shockproof.
- Automotive and Marine Industries: Used for sealing the gaps in automotive glass installation, ship
deck joints, and other areas, leveraging its weather resistance and
corrosion resistance to adapt to harsh operating environments.
- DIY and Household Repairs: A versatile tool for household maintenance, such as repairing
leaking windows, sealing cracks in ceramic tiles, or bonding loose
household items, offering a convenient and effective solution for
minor repairs.
