High-resolution imaging capability for sub-50 µm line/space patterns on metal and polymer-based printing plates.
Optimized sensitivity to 405 nm LED exposure systems, enabling fast and energy-efficient plate processing.
Excellent adhesion to aluminum, steel, and polyester substrates without requiring additional primers.
Low development time in standard aqueous alkaline developers (e.g., 1–3% Na₂CO₃), reducing cycle time and wastewater load.
Stable shelf life of ≥12 months when stored at 5–25 °C under inert atmosphere and light-protected conditions.
Direct laser imaging (DLI) of offset printing plates for commercial and packaging printing.
Flexographic plate production for corrugated board and label applications requiring high edge acuity.
Gravure cylinder pre-coating for proofing and short-run production workflows.
Industrial screen printing stencil fabrication on stainless steel and nickel mesh substrates.
Prototyping of functional micro-patterned surfaces in R&D labs for printed electronics substrates.

Q1: What is the CAS Registry Number for KEY-DLS-H330?
A: The CAS number for KEY-DLS-H330 is 1985732-88-1. This identifier applies to the formulated product as supplied; individual components have separate CAS entries available upon request under NDA.
Q2: What is the recommended coating thickness and solids content for optimal performance?
A: Apply at 12–15% w/w solids (diluted with recommended PGMEA or ethyl lactate) to achieve a dry film thickness of 1.8–2.2 µm after soft bake. Thickness outside this range may compromise resolution or adhesion.
Q3: How does KEY-DLS-H330 compare to KEY-DLS-H220 in terms of resolution and throughput?
A: KEY-DLS-H330 offers higher resolution (≤45 µm L/S vs. ≤60 µm for H220) and 25% faster exposure speed at 405 nm, but requires tighter process control. H220 remains preferred for high-speed, high-volume production where resolution >60 µm is acceptable.
Q4: Is KEY-DLS-H330 compliant with food-contact regulations for packaging applications?
A: Yes — fully compliant with EU Regulation (EC) No. 1935/2004 and FDA 21 CFR §175.105 for indirect food contact when fully cured (post-bake ≥110 °C for 10 min) and tested per EN 13130-1 for overall migration (≤10 mg/dm²).
Q5: Has migration or extractables testing been performed for pharmaceutical-grade plate applications?
A: Yes — certified extractables data (per ICH Q5C & USP <661.1>) is available for key leachables (DNQ derivatives, novolac fragments, solvent residuals) under standard curing conditions; full report provided with lot-specific CoA upon order.
