Analysis of Alkyd Coatings
• 27% of resins for solvent-based coatings are alkyds, 540 MM lbs.
• Alkyd coatings contribute to VOC emissions
• Existing Low VOC-capable resins compromise on performance:
– Low molecular weight alkyds� Slow dry
8
– Low molecular weight alkyds Slow dry
– Exempt solvents are expensive and/or w/ undesired odor / performance
– Acrylic emulsion resins offer low VOC solution but have short open times, low gloss, and
reduced corrosion resistance; i.e. undesired attributes for many applications

Alkyd building blocks originate from petroleum-based and vegetable-based
oil feedstocks. The use of Sefose sucrose polyesters decreases the overall
quantity of petroleum-based materials required.
Health and Safety
• Common petroleum hydrocarbon solventshydrocarbon solventshydrocarbon solventshydrocarbon solvents are toxic, have low flash points, are
combustible and show adverse health effects; i.e. asthma, neurological effects.
• Sefose has very high flash point and is non-toxic
• Over 3 million interior architectural coatings project sites per year could see reduced
pollutant levels as a result of CHEMPOL® MPS alkyd paints.
