Chemical Analyst- Glass fiber

Chemical Technologist – Sizing Formulation

KEY RESPONSIBILITIES

• Develop and optimize sizing formulations for fiber — direct roving and assembled roving
• Ensure sizing compatibility with epoxy, vinyl ester, polyester, phenolic, polypropylene, polyamide, and polyurethane resin systems
• Control and improve fiber performance properties: tensile strength retention, filament integrity, abrasion resistance, and weaving performance
• Conduct laboratory testing, trials, and scale-up validation in the production environment
• Troubleshoot sizing-related production issues and deliver actionable technical solutions
• Collaborate with the Q&C team to standardize formulations across application segments: construction, composites, and thermoplastic reinforcement
• Maintain rigorous documentation of formulations, trials, and technical reports

REQUIRED QUALIFICATIONS

• Degree in Chemistry, Chemical Engineering, Polymer Science, or a related discipline
• 3–5 years minimum experience in fiber sizing, polymer coatings, or composite materials; glass fiber or basalt fiber background strongly preferred
• Strong command of polymer chemistry, silane coupling agents, epoxy systems, and resin-fiber interaction mechanisms
• Proven experience in laboratory formulation development and industrial scale-up
• Background in textile or reinforcement fiber processing is an advantage

KEY TECHNICAL COMPETENCIES

• Fiber surface treatment and sizing chemistry
• Adhesion promotion mechanisms, including silane chemistry
• Thermal and mechanical stability of coatings
• Compatibility testing with construction resins (cementitious and epoxy systems)
• Data analysis and process optimization

PERSONAL PROFILE

• Strong analytical and problem-solving mindset
• Comfortable operating at the Q&C and production interface
• Disciplined in documentation and detail
• Collaborative, with clear communication skills across technical and non-technical stakeholders
