| Appearance | Red / Blue milky liquid, SBQ one‑component pre‑sensitized, no extra photosensitizer required |
| Package | 1KG / 5L plastic drum |
| Application | Universal SBQ photopolymer emulsion, compatible with conventional‑UV, LED exposure and CTS laser direct imaging.Suitable for textile printing, plastisol ink printing, signs & nameplates, membrane switches. Compatible with plastisol, solvent‑based and partial water‑based inks. Ideal for high‑volume screen shops and equipment with low‑power light source. |
| Features | Solid content:41%; Viscosity:5000‑5500 cps @25 °C;Dry stencil thickness:3‑5 μm;Resolution on 350‑mesh yellow mesh:36‑42 μm;Minimum resolution on 420‑mesh yellow mesh:31‑36 μm;Excellent solvent & humidity resistance, stencil non‑tacky under high‑humidity condition;Ultra‑fast exposure for higher production efficiency;Good mesh bridging for coarse mesh, easy coating control & fast drying;Tough stencil for long print‑run, sharp dot‑edge performance;Easy reclaiming; high‑contrast color for convenient stencil inspection. |
| Storage & Shelf‑life | Store at 5‑25 °C in cool dark place. 12‑month shelf‑life for unopened drum. Use promptly after opening. |
二. Operating Instructions
⚠️Note: SBQ one‑component emulsion, no photosensitizer to mix. Operate only under yellow safelight.
1.Mesh Pretreatment Degrease mesh with degreaser. Roughen mesh with abrasive paste for normal jobs; skip roughening for high‑mesh fine stencils.
2.Dry screen for use at 35‑40 °C (max.42 °C), ambient humidity 45‑55%.
3.Coating & Drying (adjust passes as required) ‑ Ink‑side 2 passes + Print‑side 2 passes; dry 35‑40 °C, humidity 45‑55%, 10 min ‑ Ink‑side 1 pass + Print‑side 3 passes; dry 35‑40 °C, humidity 45‑55%, 10 min ‑ Ink‑side 0 pass + Print‑side 1 pass; dry 35‑40 °C, humidity 45‑55%, 10 min Net dry stencil thickness approx.7‑8 μm. Adjust coating passes for target film‑thickness.
4.Exposure (UV metal‑halide lamp / LED / CTS laser) Determine optimal exposure time by exposure step‑wedge film. Insufficient exposure leads to poor solvent‑resistance & short print‑life; over‑exposure reduces resolution. Retest parameters after light‑source replacement. Rest screen for 1‑3 minutes after exposure.
5.Development (Wash‑out) Wet both sides of screen with low‑pressure water (soak ≤1‑2 min), wait 1‑2 min. Spray print‑side with fan‑shaped low‑pressure water until image appears clearly.
Focus washing on print‑side. Avoid excessive rinsing on ink‑side to prevent pinholes. Water‑gun distance approx.60 cm from screen. Gently rinse ink‑side for 1‑2 min, wash away emulsion scum on both sides.
6.Post‑development drying: 35‑40 °C (max.42 °C), humidity 45‑55%, for 20‑30 min.
7.Screen inspection & repair. Secondary post‑exposure is available for longer print‑run.
8.Block‑out the screen.
三. Storage, Handling & Safety Notes
Water‑miscible, non‑flammable, low environmental hazard. May cause mild skin irritation; low inhalation risk under normal temperature.
First‑aid measures
‑Inhalation: Low volatility, negligible inhalation hazard. ‑ Ingestion: Rinse mouth thoroughly. Do NOT induce vomiting. Seek medical attention if discomfort occurs. ‑ Skin contact: Remove contaminated clothing, wash skin with soap and running water. ‑ Eye contact: Remove contact lenses. Flush eyes & eyelids with plenty running water for ≥15 minutes, seek medical help if irritation persists.
Personal Protection
Ensure good ventilation; handle under yellow safelight. No eating, drinking or smoking in working area.
Storage
Store at 5‑25 °C, avoid high‑temperature and direct sunlight.
Pre‑sensitized SBQ emulsion, activity declines quickly once opened, use as soon as possible.
