The PositionLaboratory Technician - Sustainable Constructions Job Summary Job Summary The Laboratory Technician in Sustainable Construction S&T team will support the Research & Development (R&D) departments in the formulation, application, and testing of a diverse portfolio of coating technologies, including liquid paints, powder coatings, and specialty finishes. This is not a routine testing role; it requires a highly adaptive candidate capable of engaging in dynamic lab method development tailored to specific customer applications. Utilizing a strong scientific background in chemistry, material or chemical engineering, this role requires conducting precise analytical tests, preparing lab-scale batches across different mediums, and ensuring all products meet strict industry and customer specifications. Key Responsibilities Method Development & Adaptive Testing Actively participate in lab method development to create, adapt, and validate new testing procedures for unique customer applications and changing project needs. Perform standard wet-state or uncured testing, such as viscosity (Krebs, Brookfield), density, fineness of grind (Hegman gauge) for liquids, and gel time, flow, or particle size analysis for powders. Conduct comprehensive physical and mechanical testing on cured films, including film thickness, gloss, color matching (spectrophotometer), adhesion (cross-hatch), impact resistance, flexibility (conical mandrel), and hardness. Assist in chemical and environmental resistance testing (e.g., salt spray corrosion, humidity, MEK solvent rubs, and UV weathering). Formulation & Batch Preparation Assist chemists, scientists and engineers in the development and modification of both liquid and powder coating formulations. Prepare lab-scale batches of powder coatings (involving weighing, pre-mixing, extrusion, and grinding/milling) and liquid coatings (utilizing high-speed dispersers, bead mills, and mechanical stirrers). Safely and accurately measure and handle raw materials, including solvents, resins, pigments, curing agents, and additives in both liquid and powder forms. Application & Preparation Apply coatings to various substrates (metal, wood, plastic, or paper) utilizing the appropriate method for the technology, including electrostatic powder spray equipment, conventional liquid spray guns, wire-wound drawdown bars, or dip coating. Prepare test panels by cleaning, sanding, or chemically treating surfaces. Monitor and record drying and curing times, operating laboratory baking ovens for powder/thermoset coatings or monitoring ambient cures for air-dry liquid systems. Laboratory Maintenance, 5S & Safety Strictly champion and maintain a clean, organized, and highly efficient workspace in strict accordance with 5S principles (Sort, Set in order, Shine, Standardize, Sustain) and Safety. Calibrate, clean, and perform routine maintenance on laboratory instruments and application equipment (both liquid and powder setups). Strictly adhere to all Environmental Health and Safety (EHS) guidelines, including the proper handling and disposal of hazardous chemicals, flammable liquids, and airborne particulates, as well as the use of required Personal Protective Equipment (PPE). Data Analysis & Documentation Record detailed and accurate experimental data, observations, and test results in a Laboratory Information Management System (LIMS) or standard lab notebooks. Analyze test data to identify trends, troubleshoot formulation issues, and recommend adjustments. Draft technical reports and standard operating procedures (SOPs) for internal stakeholders. Qualifications & Requirements Education Required: Bachelor's Degree (B.S.) or Associate's Degree (A.S.) in Chemistry, Chemical Engineering, Polymer Science, or Materials Science, or similar areas of study.. Experience 0-3 years of laboratory experience, with a strong preference for candidates who have hands-on, non-routine project experience rather than routine assay testing. Prior experience in the paints, resins, or coatings industry is a strong plus but not strictly required. Technical & Soft Skills Adaptability: Proven ability to quickly pivot between different testing methodologies, customer projects, and formulation challenges required for liquid versus powder technologies. Strong understanding of fundamental chemistry principles, particularly polymer chemistry, cross-linking mechanisms, and physical chemistry. Analytical Thinking: Ability to interpret data, troubleshoot formulation issues, and apply the scientific method to solve complex problems. Attention to Detail: High level of precision when measuring chemicals and recording test results. Communication: Excellent written and verbal communication skills to effectively relay technical information. Physical Demands & Work Environment Ability to stand for extended periods and perform repetitive tasks. Ability to safely lift and move materials up to approximately 40 pounds (occasionally) Comfortable working in a laboratory environment with exposure to chemical odors, solvents, fine dust (from powder coatings), and varying temperatures from curing ovens. Must be comfortable wearing respirators and other protective gear as required.
