Introduction To Bio-Based Applications In The Coatings Industry And Trends

Compared to traditional petroleum-based materials, bio-based coatings are primarily plant-based, reducing CO2 emissions and dependence on petroleum, and are produced in a greener way, in line with the desire for environmental protection and sustainability.

The market for biopolymer coatings is expected to exceed US$1.3 billion by 2024. The 13th Five-Year Plan for China's coatings industry states that by 2023, the total value of China's coatings industry is expected to grow to around RMB 690 billion.

It can be expected that, thanks to the research and development of Carpenter's bio-based paints, more paint companies will be committed to the research and development of environmentally friendly paints, providing more solutions for environmental protection and promoting green economic and social development.

Research and development of vegetable oil coatings and other future trends

Scientists and scholars recognise that vegetable oils and fats are renewable resources and that research and development of vegetable oil coatings is the way forward.

Expanding the sources of non-edible oils for paints has great potential in the country, and together with policy support, bio-based paints have great potential for development.

In addition, according to the characteristics of the molecular structure of grease and alkyd resins, they can be modified in various ways, such as phenolic, amino, epoxy, acrylic, polyurethane, silicone, fluorine resin, hydrocarbon resin and natural resin.

In order to improve the physical and chemical properties of the coatings and make them widely used in different industries and different fields.

Bio-based heavy-duty anti-corrosion coatings (cashew nut oil epoxy resin system), water-based biological nano-waterproof coatings, water-based biological rust-proof coatings, bio-based antifouling coatings (using natural antifouling agents, i.e. using substances extracted from a variety of marine and terrestrial plants and animals to prevent fouling by sea creatures, to produce antifouling coatings), etc. have been introduced one after another.
