FAQs of Dimer Acid
Q:What are the main uses of dimer acids?
A:Dimer acids are mainly used as raw materials for the production of inks, coatings, plastic additives, lubricants, adhesives and synthetic resins. Due to its unique physical and chemical properties, dimer acid is able to improve the performance of products, such as enhancing abrasion resistance, weatherability and corrosion resistance.
Q:How is dimer acid produced?
A:The production of dimer acids is mainly achieved by chemical synthesis, a process that involves the catalytic dimerisation of long-chain monomeric fatty acids (e.g. linoleic acid) at elevated temperatures. During this process, precise control of temperature, pressure and catalyst selection is required to ensure that high purity and high yield dimer acid products are obtained.
Q:What is the environmental impact of dimer acids?
A:Dimer acid, as a biodegradable chemical, decomposes naturally after use, reducing its long-term impact on the environment. However, the wastewater and exhaust gases that may be generated during its production and treatment can still cause some negative impact on the environment if they are directly discharged without proper treatment. Therefore, the adoption of environmentally friendly production processes and effective waste treatment measures is essential to reduce the environmental impact of dimer acids.
Q:What are the types of dimer acids?
A:Depending on different raw materials and production methods, dimer acids can be classified into various types, commonly including dimer acids based on vegetable oils (e.g., soybean oil, flaxseed oil, etc.) and dimer acids based on animal fats. In addition, there are functional dimer acids obtained by specific chemical modifications, such as modified dimer acids containing epoxy groups or hydroxyl groups, which have a wider range of uses and better properties.
