Adhesively bonding materials can be complex at times due to the boundary between the two materials beingx000D
joined. Poor bonding can be caused by surface contaminations, improper installation procedures or simply notx000D
using the right bonding product. In addition, it is possible that the type of adhesive works well for one materialx000D
but may not be as effective for a different material.x000D
The objective of this study will determine if one adhesive can work well for all types of crystal jewelryx000D
submitted to different scenarios and if a unique preparation process for the crystals and adhesives are required.x000D
The research supported by this NSERC Engage Grant will investigate the use of a variety of commerciallyx000D
available adhesives on four crystal types. The adhesive bond strength will be evaluated under differentx000D
conditions such as: contaminates on the as-received crystal surfaces, epoxy-clay adhesive mixing time, workingx000D
times and curing temperature. The bonded crystals will also be subjected to temperature fluctuations (+35°C tox000D
-35°C) to reproduce real world applications and their bond strength assessed. By employing an optimizationx000D
technique, the best formulation will be determined for the best bond strength.x000D
The performance of the selected adhesives will enable recommendations to be made related to their adhesionx000D
ability and crystal surface preparation technique. It is anticipated the research will provide a faster, morex000D
reliable assembling technique than the previous approach. An innovative, unique step-by-stepx000D
solution/procedure to provide a high strength bond between jewelry and epoxy-clay adhesives will be provided.
