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.
