• Plan, perform, and interpret laboratory testing including:
  • Lap shear and peel adhesion testing
  • Cure kinetics evaluation
  • Rheology and viscosity analysis
  • Shore A/D hardness testing
  • Tensile strength and elongation testing
  • Compression set evaluation
  • Fatigue and cyclic durability testing
  • Environmental exposure testing (temperature, humidity, UV)
  • Outgassing analysis
  • Chemical resistance testing
• Develop, validate, and maintain manufacturing application processes including dispensing, priming, curing, bonding, and pot life controls.
• Lead root cause investigations of adhesive, sealant, elastomer, and rubber failures; implement and monitor corrective and preventive actions (CAPA).
• Support manufacturing scale-up, production transfer, and continuous improvement by developing work instructions, process control plans, manufacturing trials, and operator training.
• Qualify and audit suppliers of raw materials, adhesives, sealants, and elastomeric components; review supplier certifications, test reports, and certificates of conformance.
• Ensure compliance with ASTM, aerospace outgassing requirements, D6 standards, and other applicable industry and regulatory specifications.
