UV resin is an important component in UV coatings

UV resin is polymerized with environmental friendly raw materials and new technologies. It has medium hardness, water-based, no VOC pollution, low toxicity, non combustibility, good adhesion to paper, good flexibility. The product can be diluted with water according to the viscosity needs. The viscosity of the product is moderate, and the ink is good on the roller coating and printing ink system. The product is yellowish and clear. After curing, the paint film is highly transparent and can be used with some oily monomers to obtain high hardness and high scratch resistance, Characteristics: a low viscosity special Modified Polyurethane Acrylic UV resin, which has unique adhesion, boiling resistance, water bubble resistance and other characteristics on the surface of inorganic glass and hardware. It is recommended for cigarette bags, circuit boards, glass, hardware, ceramics and other materials.
UV resin function: low viscosity, especially suitable for UV ink-jet and 3D printing, with good wettability, low viscosity, high solid content and low shrinkage, good adhesion to glass and metal, chemical resistance, water boiling resistance and water bubble resistance. Application range: UV ink-jet, 3D printing, UV ink on glass, hardware, UV ink on ceramic, UV alkali washing ink, glass UV glue, etc. UV resin is composed of polymer monomer and prepolymer, In which a light (ultraviolet) initiator (or photosensitizer) is added. Under the irradiation of ultraviolet light (250-300 nm) of a certain wavelength, the polymerization reaction is immediately caused to complete the curing. Photosensitive resin is generally liquid, and is generally used to make materials with high strength, high temperature resistance and waterproof.

UV resin is a proportion component of UV coating, and is the matrix resin in UV coating. Generally, it has groups that can further react or polymerize under light conditions, such as carbon carbon double bond and epoxy group. According to the type of solvent, UV resin can be divided into solvent type UV resin and aqueous UV resin Solvent based resins do not contain hydrophilic groups and can only be dissolved in organic solvents, while aqueous resins contain more hydrophilic groups or hydrophilic segments and can be emulsified, dispersed or dissolved in water. Aqueous UV resins refer to UV resins that are soluble in water or can be dispersed in water. The molecules contain a certain number of strong hydrophilic groups, such as carboxyl, hydroxyl, amino, ether, acylamino, etc., and unsaturated groups, such as acryloyl, Methacryloyl or allyl. Waterborne UV trees can be divided into three types: lotion type, water dispersion type and water-soluble type It mainly includes three categories: waterborne polyurethane acrylate, waterborne epoxy acrylate and waterborne polyester acrylate.
