What are Polyester Acrylates and How are They Used?
2023/5/24
Polyester acrylates are a type of polymer that are formed by the reaction of acrylic acid or its derivatives with polyesters. They are widely used in various industries, such as coatings, adhesives, printing inks, plastics, and textiles.
Polyester acrylates have many advantages over other types of polymers, such as:
They have high reactivity and fast curing speed, which makes them suitable for UV and electron beam curing systems.
They have good adhesion to various substrates, such as metal, wood, glass, and plastic.
They have excellent weather resistance, chemical resistance, and abrasion resistance, which makes them durable and long-lasting.
They have low viscosity and good flowability, which makes them easy to apply and process.
They have low shrinkage and low odor, which makes them environmentally friendly and safe.
Some of the common applications of polyester acrylates are:
Coatings: Polyester acrylates are used as binders or modifiers for various types of coatings, such as industrial coatings, automotive coatings, wood coatings, metal coatings, and floor coatings. They can improve the gloss, hardness, flexibility, and adhesion of the coatings.
Adhesives: Polyester acrylates are used as components or additives for various types of adhesives, such as pressure-sensitive adhesives, structural adhesives, laminating adhesives, and sealants. They can enhance the strength, durability, and stability of the adhesives.
Printing inks: Polyester acrylates are used as vehicles or diluents for various types of printing inks, such as offset inks, flexographic inks, gravure inks, and inkjet inks. They can improve the color strength, gloss, drying speed, and water resistance of the inks.
Plastics: Polyester acrylates are used as modifiers or compatibilizers for various types of plastics, such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polystyrene (PS). They can improve the impact strength, heat resistance, flame retardancy, and biodegradability of the plastics.
Textiles: Polyester acrylates are used as finishes or treatments for various types of textiles, such as cotton, wool, silk, and
polyester. They can improve the softness, wrinkle resistance, stain resistance, and antibacterial properties of the textiles.
Polyester acrylates are versatile and functional polymers that can meet the diverse needs of different industries. They are expected to have a growing demand in the future due to their superior performance and environmental benefits.
