Chromaline

Chromaline UDC-HV (Magna/Cure) is Chromaline’s most popular dual-cure emulsion — and the one most recommended for shops that need reliability across a wide range of mesh counts without having to dial things in perfectly every time. At 5,300 CPS, its higher viscosity builds a dense, uniform stencil whether you’re coating 110 mesh for heavy ink deposits or 230 mesh for finer work. Wide exposure latitude, forgiving shop condition tolerance, and full compatibility with plastisol, solvent, and UV-curable inks make UDC-HV the dual-cure workhorse for shops that want consistent results without constant tweaking. The diazo sensitizer is included.

Description

The Dual-Cure Workhorse — Chromaline UDC-HV

UDC-HV is Chromaline’s most popular dual-cure because it’s the one that works reliably in the widest range of real-world shop environments. Higher viscosity than UDC-2, wider exposure latitude than most emulsions in its class, and full compatibility with plastisol, solvent, and UV-curable inks. Shops that switch to UDC-HV often stay on it for years precisely because it doesn’t demand perfection — it delivers consistent, quality results even when humidity fluctuates, exposure times drift, or mesh counts vary between jobs. Mix the included diazo, coat your screens, and get to printing.

Why High Viscosity Matters

At 5,300 CPS, UDC-HV is thicker than UDC-2. Higher viscosity means the emulsion doesn’t sink into coarse mesh as readily — it sits on the mesh and builds up more uniformly, producing consistent EOM whether you’re coating 110 mesh for big ink deposits or 230 mesh for finer work. It bridges mesh openings more effectively across the full range of textile screen mesh counts.

Wide Latitude — Forgiveness Built In

UDC-HV has an unusually wide exposure window. Most emulsions penalize you for exposure variation — too little and the stencil washes out; too much and you lose fine detail. UDC-HV tolerates a wider range of exposure without degrading significantly in either direction. For shops without precise exposure timers or calibrated step wedge routines, this is a meaningful production advantage.

Solvent & UV-Curable Resistance

Solvent and UV-curable inks are chemically aggressive — they attack emulsions that aren’t built for them. UDC-HV’s dual-cure chemistry cross-links during exposure to produce a stencil that resists solvent penetration and holds up under UV-curable ink systems, including high-speed graphic and industrial printing applications.

UDC-HV vs. UDC-2 — Which to Choose?

UDC-2 (3,500 CPS) excels on fine mesh for halftone detail. UDC-HV (5,300 CPS) is more forgiving across the full mesh range and shop conditions — the better default for most shops. If you’re running diverse mesh counts, mixed jobs, or a shop without tight exposure calibration, UDC-HV is the right choice. UDC-2 is the specialty pick for fine detail work.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions — Chromaline UDC-HV

Why is UDC-HV Chromaline’s most popular dual-cure?

UDC-HV delivers consistent results across the widest range of shop conditions, mesh counts, and applications. Its high viscosity (5,300 CPS) coats uniformly on both coarse and fine mesh, and its wide exposure latitude tolerates variation without significant performance degradation — making it the most forgiving and reliable choice for most screen printing operations.

What is the difference between UDC-HV and UDC-2?

Both are dual-cures with the same ink compatibility. UDC-HV (5,300 CPS) is higher viscosity — better for a wide range of mesh counts and more forgiving of shop conditions. UDC-2 (3,500 CPS) is lower viscosity — better for fine mesh and halftone detail work where resolution is the priority.

Is the diazo sensitizer included with UDC-HV?

Yes — every size of UDC-HV includes the diazo sensitizer packet. Dissolve in distilled water, stir into emulsion, allow 30 minutes de-gas, then coat.

How long does sensitized UDC-HV last?

Sensitized UDC-HV lasts 4–6 weeks at room temperature — longer than UDC-2. Refrigerating extends the shelf life further. Only sensitize what you’ll use within the window.

Is UDC-HV freeze/thaw stable?

No — UDC-HV is NOT freeze/thaw stable. Frozen emulsion is permanently damaged. River City Supply ships from San Antonio, TX for more safe winter shipping days than northern distributors.
