Bio-organic silicone additives: Non-petroleum based alternative raw materials

 
There is a strong desire to move away from petroleum-based chemical feedstocks to improve sustainability. Siltech have evaluated bio-based hydrocarbon portions of some traditional organo-silicone coatings additives. This alternative supply chain feeds silicone polyethylene oxide modified organo-silicones, one of the most frequently used types of organo-silicone ingredients in coatings additives. These bio-organic silicone additives are either synthesized from corn derived ethanol or from plant-based alpha olefins. In this paper we compare several additives made from these bio-sourced feedstocks to the conventional petroleum-based products. Comparison data across several coatings systems shows that the origin of the organic portion of these is not decisive to performance.
