| Résumé : |
How a stable alkyd emulsion based on TOFA can be formulated into water-borne coatings and how it compares with other fatty acids as a fit-for-purpose, sustainable alternative for the coatings industry. |
| Note de contenu : |
- Responsible sourcing
- No deforestation or competition
- Small footprint
- Characterisation methods
- Preparing the emulsions
- From paste to paint
- Differences in fatty acid compositions
- Similar molecular masses
- More double bonds means greater hardness
- Hardness of coatings reflects double bond content
- Gloss retention varies with conditions
- Low iodine value, low yellowing
- A sustainable alternative
- Table 1 : The composition in wt% of the fatty acids used in this study. Row 'FAtot' represents the total percentage of fatty acids determined in the samples. The values in brackets for the C18:2 fatty acid refer to conjugated fatty acids
- Table 2 : Characteristics of the alkyds as prepared
- Table 3 : Volume average diameter for the alkyd emulsions prepared at two different surfactant levels. The alkyds are named after the fatty acid that was used |
