A Comprehensive Evaluation of the Performance and Materials Chemistry of a Sililcone-Based Replicating Compound
- Univ. of Dallas, Irving, TX (United States)
The objective of this project was to characterize the performance and chemistry of a siliconebased replicating compound. Some silicone replicating compounds are useful for critical inspection of surface features. Common applications are for examining micro-cracks, surface pitting, scratching, and other surface defects. Materials characterization techniques were used: FTIR, XPS, ToF-SIMS, AFM, and Confocal Microscopy to evaluate the replicating compound. These techniques allowed for the characterization and verification of the resolution capabilities and surface contamination that may be a result of using the compound. FTIR showed the compound is entirely made from silicone constituents. The AFM and Confocal Microscopy results showed the compound does accurately replicate the surface features to the claimed resolution. XPS and ToF-SIMS showed there is a silicone contaminant layer left behind when a cured replica is peeled off a surface. Attempts to clean off the contamination could not completely remove all silicone residues.
