NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of its advanced product, L-6902 UV curing Polyurethane Resin. This innovative material is a high-performance polyurethane acrylic oligomer specifically designed to meet the demanding requirements of modern UV curing applications, particularly in coatings and inks requiring superior durability and protection.

L-6902 is characterized by its remarkable properties, making it an ideal choice for formulators seeking enhanced performance. As a 15-functional oligomer, it boasts high reactivity and enables the creation of coatings with a high crosslinking density. This molecular structure contributes significantly to the resin's excellent resistance to solvents, abrasion, and general wear.

A standout feature of L-6902 is its exceptional steel wool resistance, demonstrated by performance exceeding 5000 cycles in standard tests. This makes it invaluable for surfaces prone to physical contact and potential scratching, ensuring longevity and maintaining aesthetic appeal. Furthermore, the resin provides a combination of high hardness and appropriate flexibility, striking a crucial balance for durable coatings that resist cracking or becoming brittle.

Technical specifications highlight L-6902 as a colorless transparent liquid with a viscosity ranging from 35,000 to 75,000 Cps at 25ºC. It has a UV component of ≥98%, a density of 1.1 ± 0.1 g/cm³ at 25ºC, and a Shore hardness of 88D. These parameters ensure reliable processing and consistent performance in various UV curing systems.

Applications for L-6902 UV curing Polyurethane Resin are diverse, including anti-scratch UV coatings, UV anti-graffiti coatings, and high-abrasion resistance UV inks. Its excellent adhesion profile extends to various plastic substrates such as PC, ABS, PMMA, PET (with surface treatment), and TAC, broadening its utility across different industries.

In addition to its physical and chemical properties, L-6902 exhibits good weatherability, yellowing resistance, and strong performance under QUV lamp testing, ensuring long-term stability and appearance retention even under challenging environmental conditions. Its fast curing rate further enhances production efficiency.
