Lab Evaluation Checklist for Water‑borne Coating & Ink Additives

Introducing new additives always requires strict lab assessment before plant‑scale manufacturing. Missing key test items may cause unexpected failure during production. We compiled a practical checklist for your reference when evaluating defoamers, wetting agents, dispersants and leveling agents.

Essential evaluation items:

1. Basic compatibility: visual check for separation, flocculation or haze after additive mixing into base formula.
2. Core functional test
   • Defoamer: macro‑foam collapse speed, micro‑foam / pinhole observation, crater risk assessment.
   • Wetting agent: substrate spreading status, fish‑eye / crawling check.
   • Dispersant: grinding viscosity, colour strength, gloss, pigment sediment after accelerated ageing.
   • Leveling agent: surface smoothness, orange‑peel, re‑coating / inter‑layer adhesion performance.
3. Storage stability: heat‑ageing test (50℃‑60℃ for 7‑14 days), freeze‑thaw cycles.
4. Application simulation: mimic real‑world processing such as high‑speed stirring, printing / spraying conditions.
