PET-9800 Membrane Switch Screen Printing Ink
1. Обзор и области применения
The PET-9800 is a premium solvent-based, 1-component screen printing ink. It can also function as a 2-component ink by adding the B-11 hardener to further enhance chemical resistance and adhesion. It is specifically formulated for the electronics and appliance industries.
- Подходящие основания: PC (Polycarbonate) films and print-treated PET films.
- Основные области применения: Graphic overlays, membrane switches, and touch panels.
- Performance Features: Offers exceptional adhesion, outstanding thermoforming/embossing capabilities, and excellent compatibility with double-sided mounting adhesives. It resists color floating (mottling) during custom color mixing, ensuring absolute batch-to-batch consistency.
2. Environmental Compliance
Formulated with strict adherence to global environmental standards:
- Fully complies with EU RoHS directives.
- 100% Free of Polycyclic Aromatic Hydrocarbons (PAHs), Heavy Metals, Diphenyl Ethers, PBDEs, and Phthalates.
- Formulated without environmentally hazardous solvents such as benzene.
3. Модели продукции и цветовая гамма
Solid & Transparent Colors
- Standard Series (NH): "NH" denotes high lightfastness (fade-resistant). Includes Extra White, Insulating Black, Piano Black, Lemon Yellow, Red, Blue, Green, Clear Varnish, etc.
- High-Opacity Series (NH-G): Excellent hiding power. Prevents color shift when printing over black backgrounds. High lightfastness.
- Transparent Series (NH-T): Extremely clear tints (Red, Yellow, Blue, Green, Purple, Black). Highly recommended for tinting metallic powders to achieve brilliant, colorful metallic effects. Excellent outdoor durability.
- Fluorescent Series (D): Includes Fluorescent Yellow, Red, Blue, Green, Orange, Purple. Note: Poor lightfastness; strictly recommended for indoor use only.
Metallic (Silver/Gold) Powders & Mesh Guidelines
To ensure maximum metallic brilliance, PET-9800 does not supply pre-mixed metallic inks. Users should mix the metallic powder with thinner and Clear Varnish directly before printing.
| Metallic Powder Model | Рекомендуемое количество ячеек |
|---|---|
| Y-10 / Y-20 / Y-30 / Y-40 / Y-50 (Fine to Bright Silvers) | ≤ 300 mesh / inch |
| J-10 (Red Gold) / J-20 (Cyan Gold) | ≤ 300 mesh / inch |
| Y-70 (Fine Flash Silver) | ≤ 300 mesh / inch |
| Y-80 (Fine Flash Silver) | ≤ 250 mesh / inch |
| Y-90 (Medium Flash Silver) | ≤ 200 mesh / inch |
| Y-100 (Coarse Flash Silver) | ≤ 150 mesh / inch |
4. Инструкции по смешиванию и приготовлению
- Выбор разбавителя: 200-98 (Standard), 100-98 (Fast-Dry), 400-98 (Slow-Dry).
- Hardener: B-11 Hardener.
Стандартное соотношение смешивания
| Стандартная печать (однокомпонентная) | 100 parts Ink + 10-20 parts Thinner. Mix thoroughly. |
|---|---|
| High Adhesion / Embossing (2-Component) | 100 частей чернил + 5-10 parts B-11 Hardener + 10-20 parts Thinner. |
| Metallic Ink Preparation | Blend powder and thinner (ratio 50:100 or 100:100) into a uniform paste. Add NH-901 Clear Varnish and stir thoroughly. Use NH-T Transparent colors if tinting is required. |
Условия сушки
- «Touch Dry»: 10-20 minutes at room temperature, OR 3-5 minutes via 70°C-90°C forced baking.
- Hard Dry (Full Cure): 24-48 hours at room temperature, OR 30 minutes via 70°C-90°C forced baking.
Important Processing Note: When printing on hard-to-adhere treated PET films or when deep thermoforming/embossing is required, adding 5-10% B-11 Hardener is highly recommended. Once the hardener is added, the ink will begin cross-linking. The workable pot life is approximately от 4 до 5 часов at 25°C. Do not use the ink once this time has elapsed. Sealed ink (without hardener) has a shelf life of 24 months.
