Container House Waterproof Glue

Common waterproof glues for container houses mainly include Antai 133 waterproof caulking sealant, butyl waterproof tape, polyurethane waterproof coating, and other types. Here is a detailed analysis:

1. Antai 133 Waterproof Caulking Sealant
This product is specifically designed for metal structures such as containers and truck bodies. Its core components are butyl rubber or epoxy resin, featuring water resistance, aging resistance, and strong elastic adhesion. Its application scenarios include container joint sealing, canopy leak repair, and vehicle body rust prevention. The price ranges from 5.7 yuan to 10 yuan per bottle. Different suppliers offer 48-hour or 24-hour shipping services and support a 7-day exchange policy.

2. Butyl Waterproof Tape
Using polyisobutylene rubber as the base material, it achieves sealing through a self-adhesive layer. The product comes in various widths of rolls (5cm to 1m) and lengths ranging from 5 meters to 10 meters, with prices ranging from 3.19 yuan to 157 yuan. Its advantage lies in its easy application, as it can be directly pasted onto color steel tiles, roof cracks, and other areas. It also has anti-corrosion and weather-resistant properties, making it suitable for quick repairs of container roof joints.

3. Polyurethane Waterproof Coating
This is a polymer material formed by the reaction of isocyanate with polyether polyol, creating an elastic waterproof membrane. Representative products include Yuhong waterproof coating and Nippon roof leak repair glue, which have high-temperature resistance, UV resistance, and crack resistance. The single bucket capacity ranges from 1kg to 20kg, meeting the needs of large-area construction. Some products are formulated with sunscreen for long-term outdoor exposure. After application, attention should be paid to the film-forming time and thickness control.

4. Asphalt-Based Waterproof Membrane
This product adopts a modified asphalt and胎基 (胎基 can be translated as 'reinforcement base' or 'carrier layer' depending on context, here we use 'reinforcement base') composite process, fixed by hot melting or self-adhesion. Products such as Xuanjia Mittal asphalt membrane and Sika SBS waterproof membrane have good flexibility and puncture resistance, commonly used for the overall waterproof layer铺设 (铺设 can be translated as 'laying' or 'installation') of container roofs. During construction, attention should be paid to base treatment and overlap width to ensure waterproof continuity.

Selection Advice:

• Joint Sealing: Prioritize Antai 133 sealant or butyl tape for their elasticity to accommodate slight structural deformations.
• Large-Area Waterproofing: Use polyurethane coating or asphalt membrane for long-lasting protection through multiple coats or full coverage.
• Construction Points: Thoroughly clean the base surface, removing rust and oil stains; adopt the 'one-cloth-three-coats' process for joints (applying base treatment agent, laying reinforcement base, and covering with topcoat); conduct a 48-hour closed-water test after construction to verify effectiveness.
