Information on low-reflection coatings (LR), anti-glare coatings (AG), and hard coats for optical films.

2025.05.23

Hello everyone:


This article introduces and shares our company's latest product application in PET optical film materials that require low reflectivity, anti-glare, and a hard coat. The relevant UV coatings are as follows:

  1. Low reflectance (LR) primer: UV-R2474 => 60% ± 2.0%, dry film thickness (DFT): 3~5μm, hardness 2H.

  2. Modified UV topcoat:

  • UV-R2473 (60%), DFT: 2μm, cross-cut adhesion: 5B, abrasion resistance (steel velour #0000, 1kg/cm2, 10 cycles): no scratches, total light transmittance: >90%.

  • UV-R2478 (10 ± 1.0%), fluorine-modified, DFT: 100nm, water droplet contact angle: >110 °, reflectivity (average): <1.0%, abrasion resistance test (steel velour #0000, 2×2cm area, 1kg load): >1000 cycles.

  • UV-R2475 (60%), fluorine modified, DFT: 3μm, water droplet contact angle: >108°, abrasion resistance test (steel velour #0000, 2×2cm area, load 1kg, reciprocating cycles, speed 3m/min): >1500 cycles.

  • UV-R2466 (60%), DFT: 4~5μm, water droplet contact angle: >108°, abrasion resistance test (steel velour #0000, 2×2cm area, 1kg load, number of reciprocations, speed 3m/min): >10,000 times, total light transmittance: >90%.

  • UV-R2463 (60%), DFT: 20~25μm, Hardness: 8H, Water droplet contact angle: >105°, Abrasion resistance test (steel wool #0000, load 1kgf, reciprocating cycles, speed 3m/min): >1000 times, Total light transmittance: >90%, Flexibility (mm): R8.

Additionally, Korean PET film manufacturers use J POL series dendritic resins as primers (water-based and oil-based) and UV hard coatings. Please refer to the attached product information and instruction manual for your selection.
