In addition to conventional technical indicators, the heat shear adhesion resistance is an important criterion for evaluating the quality of butyl rubber tape. In summer, the surface temperature of steel structure roofs can be very high, and whether the butyl rubber tape can maintain a durable and strong bond is a key challenge. For high-quality butyl rubber tape, the retention rate of heat shear adhesion resistance is above 95%.

What are some construction techniques for butyl rubber tape? (List a few)

1. Substrate Preparation
The application of butyl rubber tape requires a smooth substrate with a solid surface and minimal unevenness. Steel structure materials or glass materials easily meet this requirement, but concrete surfaces are more challenging.
For steel structures, rust removal and anti-corrosion treatment must be performed before applying the butyl rubber tape. For concrete substrates, it is recommended to use an epoxy penetrating material to reinforce the surface. If the application is on a vertical surface, ensure the surface is smooth; for horizontal surfaces, the viscosity may be reduced, allowing for a certain degree of self-leveling effect.

Application Technique
When applying butyl rubber tape, the bonding effect should be tested. Based on the weather conditions, temperature, and substrate condition on the day, determine the appropriate heating duration. If the heating time is too long, the butyl rubber tape is prone to deformation; if the heating time is too short, the tape will not achieve the desired stringy bonding effect.

What are the application requirements?
The substrate for butyl rubber tape application must be solid and flat. The application temperature should not be too high or too low. The substrate must be thoroughly cleaned, free of dust and loose particles. If necessary, wipe the surface with an alcohol-based solvent. Construction should not be carried out on windy days (level 5 wind or above).
