What is the temperature range for mastics?

Explanation:
Mastics are sealants used to seal joints and protect against moisture in insulation work, so they must stay flexible and bonded across a wide range of outdoor temperatures. The range from about -20°F to 200°F keeps the material elastic in cold conditions, preventing cracks during freeze–thaw cycles, and prevents excessive softening or loss of adhesion in hot conditions, so the seal remains effective. A colder limit like -40°F would be unnecessarily extreme for typical mastics, and a higher endpoint like 100°F wouldn’t guard against hot weather and sun exposure as well. Ranges up to 300–600°F are not realistic for field mastics, as they would degrade long before reaching those temperatures. So, -20°F to 200°F best matches the real operating environments mastics must handle.
