Application/Uses
● Paint and varnish Various modified resins produced by polymerized rosin are used to make paints with good brushing performance, not easy to return to yellow, hard paint film, good gloss, and strong water resistance.
● Oil and ink 140 # polymerized rosin is used to produce varnish and varnish for high-brightness prints. The modified resin is the main material of offset printing ink. The ink has the advantages of fast fixation, high gloss, good transmission, etc .; polymerized rosin can be used to make iron varnish and iron ink; it can improve the adhesion of plastic printing ink and improve gloss.
● Adhesives and tapes Improve adhesion, improve the thermal performance of adhesive tapes, reduce product costs, and partially replace terpene resins and petroleum resins.
● Chinese medicine wax pills Improve the weather resistance and toughness of wax pills.
● Precision casting Suitable for casting of aerospace components.
● Water-based paint Produce quick-drying water-based paint and ink after amination. After printing and coating, water resistance can be restored, and the film formation is bright.
● Color material Used as a high-quality pigment surface treatment agent to make the pigment bright and bright.
