Lawter, a global leader in resin technology, offers an extensive portfolio of specialized liquid ink resins designed for demanding printing applications. From rosin-based emulsifiers for emulsion polymerization to advanced polyester resins and varnishes for metal decorating, Lawter provides the building blocks for high-performance liquid inks.
PT Jaya Warindo Abadi is proud to distribute Lawter's advanced liquid ink resin technologies across Indonesia, enabling formulators to create premium-quality liquid inks with excellent stability, printability, adhesion, and cure response.
Lawter liquid ink resins offer formulators a unique combination of properties essential for high-quality printing applications:
- High-Quality Rosin Soaps for Emulsion Polymerization: BUREZ™ series products are high-grade disproportionated rosin soaps that serve as excellent emulsifiers with low unsaponifiables and outstanding stability.
- Advanced Polyester Resins for Metal Decorating: DECOTHERM™ polyester resins provide exceptional adhesion to metals, high gloss, excellent transfer on high-speed presses, and good overcoating compatibility with water-based coatings.
- Fast-Curing Metal Decorating Varnishes: Specialized varnishes designed for drawn aluminum cans and conventional steel/tin plate lithographic inks offer fast cure rates, allowing reduced oven temperatures or increased line speeds.
- Specialized Curing Systems: Complete systems including hydroxyl-functional polyesters, melamine cross-linkers, and blocked acid catalysts for optimized curing at elevated temperatures.
- Excellent Rheological Control: Structured polyester resins provide non-Newtonian rheology, resulting in highly structured inks with significant reduction in misting at lower tack levels.

Note: DECOTHERM™ 220 E, 260 E, and 290 E are typically cured with melamine resins (such as HMMM) using DECOTHERM™ 256 E as the curing catalyst. These systems provide optimized performance for high-speed metal decorating applications.
BUREZ™ products should be stored to avoid freezing and direct sunlight at temperatures between 5-35°C (drums). DECOTHERM™ products should be stored at 10-30°C in tightly closed containers. Shelf life varies by product: BUREZ™ series (9 months), DECOTHERM™ 1720 C (6 months), DECOTHERM™ 290 E (12 months), and other DECOTHERM™ polyesters (24 months).
