Waterproof Glue for Container House Connections
Commonly used waterproof glues for container house connections include butyl sealant, neoprene sealant, and MS sealant. Additionally, there are waterproof tape or sealants made of materials such as silicone rubber, ethylene propylene diene monomer (EPDM), and polytetrafluoroethylene (PTFE) available for selection.
Butyl Sealant: It has a physical state similar to putty and remains soft at all times. It possesses extremely strong adhesion and can firmly bond various materials such as metal, glass, and concrete. It has an extremely wide temperature resistance range and can be used stably in environments from minus 40 degrees Celsius to 120 degrees Celsius. It also has excellent anti-ultraviolet and anti-aging properties, remaining crack-free after 20 years of exposure to wind and sun. It is especially suitable for sealing container house connections that are exposed outdoors for long periods.
Neoprene Sealant: Its core advantage is rapid curing. For example, models like Jitai 123 can achieve leak repair effects immediately after extrusion, significantly shortening the construction cycle. Some products support surface painting, allowing them to match the color of the container's exterior facade and meet the needs of repair scenarios with high aesthetic requirements.
MS Sealant: It has high elasticity with a tensile rate of up to 400%. It can effectively absorb the deformation caused by temperature changes or structural vibrations in containers, preventing the sealing layer from cracking. Its dynamic adaptability makes it an ideal choice for movable gaps and connection nodes in container houses.
Sealing Materials of Other Materials: Silicone rubber sealant has excellent high and low-temperature resistance (-60°C to 250°C) and electrical insulation properties. EPDM sealing strips are known for their strong weather resistance and high chemical stability, often used for door and window sealing. PTFE sealing materials, with their extremely low friction coefficient and corrosion resistance, are suitable for dynamic sealing needs under special working conditions.
In practical applications, a comprehensive selection should be made based on the usage environment of the container house, the characteristics of the connection parts, and construction requirements: Butyl sealant is preferred for outdoor long-term exposure scenarios; neoprene sealant is suitable for emergency repair or aesthetic requirement scenarios; MS sealant is recommended for dynamic connection parts; and special materials such as silicone rubber can be considered for extreme temperature or chemical corrosion environments.
