About PT. Dover Chemical

PT. Dover Chemical is headquartered in Cilegon, Banten, and was founded in 1960. Its synthetic resins and polyurethane binders are essential in enhancing film formation, adhesion, gloss, flexibility, and chemical resistance in coatings. Specialty chemicals similarly include agents that may function as stabilizers, modifiers, or performance enhancers. By offering such chemistries, Dover supports formulators in tailoring coatings with improved durability, adhesion, appearance, and resistance to environmental stressors.

PU 2123 RMV

PU 2123 RMV by PT. Dover Chemical is a polyurethane resin that features a backbone with repeating -NHCOO units, attributed to the strong polar groups in urethane. It is specially formulated for white ink and can also be used for colored inks. <br> <ul style="padding-left: 40px;"><li>It offers excellent adhesion to PET film substrates and strong resistance to yellowing. </li> <li>It provides good opacity in white inks and good resoluble property. </li> <li>It also provides good glossiness and color strength. </li> <li>It has wide compatibility with organic solvents and good solvent release properties. </li> <li>It offers good heat resistance, making it suitable for boiling and retort lamination processes. </li> <li>It is toluene-free and possesses an aliphatic structure that provides excellent resistance to yellowing and UV stability. </li> <li>PU 2123 RMV requires the addition of a curing agent in the printing process when used for anti-retorting laminating inks. </li> <li>It significantly enhances durability and film-forming properties. </li> <li>It provides excellent adhesion to corona-treated PET film without requiring an adhesion promoter, while for BOPP, PE, and nylon films, the addition of an adhesion promoter is recommended. </li> <li>It has demonstrated good compatibility with various resins, showing good affinity and wettability with pigments and dyes, good compatibility with resins such as VC/VAC and NC, and solubility in esters, ketones, and aromatic solvents. </li> <li>It is perfectly suited for food packaging and gravure printing ink applications. </li> <li>It is a versatile binder designed for one-component and two-component systems, meeting the specific demands of ink formulations. </li> <li>It has a shelf life of 1 year when stored in its original, unopened container. </li></ul>

NMA 48

NMA 48 by PT. Dover Chemical is an aqueous solution of n-methylol acrylamide, a bifunctional monomer containing both vinyl and hydroxymethyl groups. This dual functionality allows polymers to be synthesized through various methods, including emulsion, solution, or suspension polymerization techniques. <br> <ul style="padding-left: 40px;"><li>The hydroxymethyl groups are self-cross-linkable under moderate conditions and can be reacted separately by adjusting the reaction parameters. </li> <li>For instance, the hydroxymethyl group can first react with a substrate like cellulose and subsequently undergo cross-linking via free radical polymerization.</li> <li>NMA 48 is used in a wide range of applications, including binders in papermaking and paper coatings, antistatic agents in textiles, non-woven textile finishes, surface coating resins for varnishes and paints.</li> <li>It has a shelf life of 10 months.</li></ul>
