How do temperature fluctuations impact adhesive bonds in stone animal sculptures?

Temperature fluctuations can significantly impact the durability and strength of adhesive bonds in stone animal sculptures. When exposed to repeated heating and cooling cycles, adhesives expand and contract, leading to stress fractures, weakened bonds, and eventual failure. Materials like epoxy, polyurethane, and acrylic adhesives react differently—some become brittle in cold temperatures, while others soften in heat.

Moisture absorption due to temperature changes can further degrade adhesives, especially in outdoor sculptures. To mitigate these effects, selecting temperature-resistant adhesives, ensuring proper surface preparation, and applying protective sealants are crucial. Understanding these factors helps preserve the structural integrity and artistic value of stone animal sculptures over time.
