Selection of Sealants for Container Mobile Houses
The selection of sealants for container mobile houses should be based on the specific usage environment and performance requirements. It is recommended to use silicone sealants, polyurethane sealants, butyl rubber sealant tapes, acrylic sealants, neoprene sealants, or MS sealants. Here is a detailed analysis:

Silicone Sealants: They have a wide temperature resistance range (-50°C to 250°C) and strong weather resistance, making them suitable for extreme climatic conditions such as extremely cold or hot regions. Their excellent elasticity allows them to stretch and contract with joint deformations, preventing cracking. Additionally, they have strong adhesion and outstanding waterproofing properties, making them ideal for outdoor environments with large temperature variations and long-term weather resistance, such as the roofs and window/door joints of container mobile houses.
Polyurethane Sealants: They feature high-strength sealing properties and strong adhesion, effectively preventing gas or liquid leakage. Their good thermal insulation performance makes them suitable for scenarios requiring reduced heat conduction, such as the wall joints of container houses. Furthermore, their wear and aging resistance make them applicable to areas with high sealing strength and durability requirements.
Butyl Rubber Sealant Tapes: They offer excellent flexibility, conforming well to irregular joints and facilitating easy construction. Their outstanding waterproofing properties, weather resistance, and aging resistance allow them to remain stable within a temperature range of -40°C to 120°C, with a service life of up to 20 years. They are suitable for scenarios with uneven joints or requiring rapid construction, such as the splicing joints of container houses or temporary repairs.
Acrylic Sealants: They are resistant to water and ultraviolet rays, dry quickly, and offer high construction efficiency. Their diverse color options meet decorative needs, making them suitable for scenarios requiring aesthetics and fast construction, such as the interior decorative joints or low-stress areas of container houses.
Neoprene Sealants: They cure quickly, with models like Jitai 123 enabling 'squeeze-and-fill' for emergency repairs. Some models support painting for both aesthetics and functionality, making them suitable for scenarios requiring rapid repair and an appealing appearance.
MS Sealants: They have excellent elasticity, stretching up to four times their original length, adapting to dynamic joints caused by container movement and preventing cracking. They are suitable for joint sealing in frequently moved or vibrated environments.
Construction Precautions:
- Thoroughly clean and dry the joint area, removing oil or dust to ensure full adhesion between the sealant and the substrate.
- Follow the material instructions strictly during construction, avoiding excessive stretching or compression to prevent seal failure.
- Avoid construction in extreme weather conditions (such as high or low temperatures) to prevent affecting the curing effect.
- Avoid touching or loading the sealant within 24 hours after construction to ensure complete curing.
