Regarding butyl sealant, the optimal service temperature range can be examined from the perspectives of standard application temperatures, high‑temperature environment handling, low‑temperature environment handling, and storage temperature requirements.
Standard construction temperature range
Butyl rubber is generally recommended for use in 5°C to 40°C Used in such environments. This temperature range ensures that the colloid’s flowability, bonding strength, and curing performance are optimized.
High-Temperature Environmental Treatment
If the ambient temperature during application exceeds 40°C, avoid direct exposure of the adhesive to sunlight or contact with high‑temperature surfaces, as this may cause premature curing or reduced flowability.
It is recommended to carry out construction during cooler periods or to appropriately cool the substrate.
Low-temperature environment treatment
When the temperature drops below 5°C, the colloid may harden and its viscosity may increase, thereby affecting the application performance.
Performance can be improved by preheating the adhesive tape (e.g., using a hot-air gun) or by raising the substrate temperature to above 10°C.
Storage Temperature Requirements
Butyl rubber shall be stored in -10℃ to 35℃ In such environments, avoid high temperatures that may cause softening or low temperatures that may lead to hardening. After prolonged storage at low temperatures, allow the material to return to room temperature before application.
