What is urethane acrylate oligomer?
Urethane acrylate oligomers are one of the major components for UV/EB (Ultraviolet light, Electron Beam and Visible light) curable coatings, adhesives, sealants and inks. UV/EB cure, in particular ultraviolet light cure of urethane acrylate oligomers, is a viable alternative to thermal cure of urethane prepolymers.
What is UV oligomer?
There are various oligomers for UV-curable protective coatings including epoxy acrylates, urethane acrylates, polyester acrylates, acrylic acrylates, hyperbranched polyester acrylates, waterborne UV pud, organic-inorganic hybrid materials and reactive amine synergists.
What is aliphatic acrylic?
An aliphatic acrylic urethane coating is a chemical compound used to protect metallic surfaces from contact with external corrosion causing agents. It is composed of several chains of urethane, which is a synthetic crystalline substance with high toughness and flexibility.
What is acrylic polyurethane?
Acrylic Urethane is a two-component, water-based gloss coating. It is designed for high performance use in industrial and commercial environments. It offers outstanding abrasion resistance and has excellent weathering properties.
What is a oligomer in chemistry?
IUPAC defines an oligomer as a substance composed of molecules containing a few of one or more species of atoms or groups of atoms (constitutional units) repetitively linked to each other.
What is difference between oligomer and monomer?
A monomer can be defined as a molecule that can combine with other molecules to form an oligomer or polymer. An oligomer can be described as a molecular complex comprised of a few monomer units.
What is the purpose of polyacrylate?
polyacrylate, any of a number of synthetic resins produced by the polymerization of acrylic esters. Forming plastic materials of notable clarity and flexibility under certain methods, the polyacrylates are employed primarily in paints and other surface coatings, in adhesives, and in textiles.
What is polyacrylate made of?
Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water….Sodium polyacrylate.
