The topic may not be a latest one for people who really are in the paint and coating industry. We have been familiar with water-based paints which are more frequent used nowadays because its dominant environmental friendly benefit. Nevertheless, the bio-based coatings have been commercially presence in the market for a couple of years, already.
Interestingly, the bio-based coatings are much more benefits. For example, increased water and chemical resistance, durable film hardness and impact resistance, reducing amounts of volatile organic compound (VOCs).
Furthermore, soybean oil is under evaluation of a reactive diluent application. An example use is the replacement of paraffin wax in coating fruit and vegetable packaging boxes in food industries.
More development to come. there are projects that cooperate between the dedicated soybean association and the coating manufacturers in the U.S., i.e.
– Use soybean oil to produce low temperature powder coatings for substrates that are
temperature sensitive.
– Use a soy-based alkyd technology platform to create a low VOC wood coating.
– Use high oleic soybean oil to make high performance hydrophobic latex coatings.
– Potential use of high oleic soybean oil to create low VOC coalescing agents for
waterborne coatings.
– Under reseach use of high oleic soybean oil-based coating for packaging fresh produce.
Commercially, there are two manufacturers – Sherwin-Williams and Rust-Oleum already having well-established soy-based paint and coating product lines.
