Outdoor applications are subjected to prolonged exposure to ultraviolet radiation, alternating high and low temperatures, and rainwater erosion; silicone sealants, which balance weather resistance with elasticity, are essential for these demanding conditions.

I. Curtain Wall and Skylight Projects

1. Structural bonding ‌ : Used for the durable bonding of glass panels to metal frames, it withstands wind pressure, seismic displacement, and thermal expansion–contraction stresses, ensuring the safety and stability of the curtain wall system.
2. ‌ Joint sealing ‌ : In unitized curtain walls, glass is sealed into the aluminum alloy joints to prevent rainwater infiltration and air leakage, significantly enhancing both airtightness and watertightness.
3. ‌ Skylight sealing ‌ : Specifically designed for sealing joints in architectural skylights, its high elastic modulus accommodates structural movement, ensuring long-term waterproofing and sealing.

Core Advantages: Silicone sealant It boasts high bonding strength, can accommodate the minute displacements of curtain walls caused by temperature fluctuations, and is also resistant to… - 40℃ Low temperature and 70℃ High temperatures—avoid thermal cycling that can cause the adhesive layer to crack.

II. Doors and Windows Works

Door and window sealing ‌ : Fills gaps between doors, windows, and walls, enhancing sound insulation and noise reduction while preventing dust infiltration, and improving energy efficiency.

Core Advantages: Silicone sealant Tolerable - 30℃ To - 40℃ Winter low temperatures (to prevent the adhesive layer from becoming brittle and leaking) and summer 60℃ The above‑mentioned exposure to sunlight (to prevent high‑temperature softening and deformation) also provides resistance against rainwater penetration and UV‑induced aging, resulting in a service life longer than that of conventional polyurethane adhesives. 3-5 Year.

III. Roof and Roof Waterproofing

Joint sealing: Sealing of metal roof lap joints, waterproofing of the joints between rooftop solar photovoltaic panels and the roof surface, and sealing at the base of roof vent pipes.   

Core Advantages: Silicone rubber’s excellent high- and low-temperature resistance can withstand day-and-night conditions. 10℃ To 60℃ It offers a significant temperature differential while exhibiting excellent water resistance and aging resistance, preventing rainwater from seeping into the roof through gaps, thereby extending its waterproofing lifespan compared to conventional acrylic sealants. 2-3 Times.

IV. Special Structures and Functional Scenarios

1. ‌ Insulated glass manufacturing ‌ : As a secondary sealant, it provides structural support, ensures glass stability, and extends the service life of insulated glass units.
2. ‌ Seismic damping ‌ : Used for joint sealing in bridges and high-rise buildings, it also provides shock absorption and cushioning, thereby enhancing structural safety.
3. ‌ Prefabricated construction ‌ : Designed to accommodate prefabricated component joints, it meets the demands of rapid construction and promotes the advancement of building industrialization.

In summary, silicone sealants are widely used in the construction industry, primarily for joint sealing, bonding and fastening, seismic damping, and providing excellent weather resistance. Moreover, selecting qualified products and applying them under appropriate conditions can ensure their safety.
