Regulations
Business Context
Automotive coating processes must achieve appearance, adhesion, corrosion protection, durability, and consistent application while reducing volatile emissions and hazardous solvent use. Lower-solvent formulations can behave differently during application, drying, curing, or surface formation, potentially affecting process stability and coating quality.
Automotive TRIZ Resolution
Rather than expecting a substitute coating to perform under unchanged process conditions, Automotive TRIZ considers the coating and application process as one system. Material formulation, atomization, temperature, humidity, surface preparation, film thickness, and curing conditions can be adjusted together to preserve coating performance with lower solvent dependence.
Applicable TRIZ Principles
Principle 2 – Taking Out reduces or removes environmentally undesirable solvents.
Principle 35 – Parameter Changes adjusts application and curing conditions to match alternative coating characteristics.
Principle 40 – Composite Materials combines material properties where a single formulation cannot efficiently provide every required function.
Expected Outcome
Reduced solvent emissions
Maintained coating quality
Lower hazardous material use
Improved environmental performance
Decision Indicators
Early indicators that this contradiction is limiting coating operations include:
Solvent reductions increase appearance or adhesion defects.
Alternative coatings are evaluated without corresponding process changes.
Emission targets repeatedly conflict with finish-quality requirements.
High-solvent formulations remain necessary to maintain process stability.
Environmental improvements increase coating rework.
Monitoring these indicators helps identify when material and process conditions must be redesigned together.
