Product

Silicone Sealant for Aluminum Composite Panel is a silicone sealant specifically developed for sealing aluminum composite panel (ACP) curtain wall systems and metal sheet structures. The product boasts excellent adhesion and sealing performance, suitable for applications such as ACP splicing, expansion joint filling, and joint waterproofing. It is a recommended material for sealing the edges of building facades.

Features of Silicone Sealant

1. Stable Adhesion

This product exhibits excellent adhesion to substrates such as ACP and aluminum alloy frames, resisting detachment and providing stable, long-lasting bonding. It is compatible with various brands of ACP panels and will not fail due to temperature differences or vibration.

2. Excellent Weather Resistance

After curing, the sealant provides long-term resistance to UV rays, rain, moisture, and pollutants. It maintains elasticity and does not crack in external wall environments, making it suitable for high-rise building facade projects and ensuring safety.

3. Adaptability to Structural Thermal Expansion and Contraction

It adapts to common thermal expansion and contraction displacements in metal sheets, with a displacement capacity of ±25% to ±50%, effectively preventing joint cracking or water seepage caused by sheet shrinkage.

4. Strong Waterproofing and Sealing Capabilities

Forms a highly sealing protective layer, preventing rainwater from seeping into the curtain wall through gaps, effectively protecting the wall insulation layer and the back structure.

5. Single-Component Room Temperature Curing

No mixing required, ready to use after opening. Moderate curing speed reduces on-site construction waiting time.

Applications of Silicone Sealant

1. Sealing Joints of ACP Panels in Aluminum Composite Panel Curtain Walls

Used for sealing joints between ACP panels on building facades, maintaining the overall structural waterproofing and visual integrity.

2. Sealing Joints Between Metal Panels and Structural Frames

Fills gaps between aluminum panels and aluminum profile frames, effectively improving sealing and airtightness.

3. Sealing Curtain Wall Corners, Edges, and Internal/External Corners

Optimizes the edge finishing effect of curtain wall designs, preventing water seepage at critical nodes while enhancing aesthetics.

4. Weatherproof Sealing Protection for Aluminum Panel Decorative Systems

Can be used for commercial exterior walls, factory metal decorative walls, and other metal structures, providing weatherproof protection.

5. Roof Metal Panel Overlap Sealing

Resists the risk of leakage caused by rain and wind pressure, extending roof life.

6. Transportation Building Metal Exterior Engineering

Widely used in the construction of aluminum facades for airports, subway stations, and train stations, improving the durability of the exterior finish.

Silicone Sealant Maintenance and Cleaning Methods

1. Regularly Inspect the Sealing Edges

Inspect the sealing line every 12 months. If cracks or detachment are found, repair or reapply the sealant promptly.

2. Clean the Exterior Wall with a Neutral Cleaner

Avoid strong acid or alkali cleaning solutions that may corrode the sealant surface.

3. Avoid Rainwater Impact on the Sealed Area Before Curing

Avoid high-pressure water washing within 24 hours after application to ensure successful adhesion.

4. Avoid Sharp Strike Abrasions to the Seal Surface

If the seal is damaged, perform local repairs to maintain its integrity.

5. Keep the Application Surface Dry and Free of Oil

Cleanliness of the application substrate improves adhesion and extends lifespan.
