PET-4600 Transparent Screen Printing Ink

1. Обзор и области применения

The PET-4600 Series is a highly transparent screen printing ink engineered for pristine optical clarity and a smooth, high-gloss finish. It is highly adaptable and can be printed as a standard 1-component ink or upgraded to a high-performance 2-component system by adding a hardener.

Подходящие основания: Treated or untreated PET sheets/films, Polyester stickers, PC (Polycarbonate) sheets, and PVC sheets/stickers.

Основные области применения: Transparent viewing windows on equipment nameplates, graphic overlays, and decorative "color crystal" glass/plastic effects.

Critical Environmental Warning: While PET-4600 complies with the EU RoHS 6 standard (free of Pb, Hg, Cd, Cr6+, PBB, and PBDE), the formulation contains Chlorine. Therefore, it is strictly prohibited for use in 3C industries (Computer, Communication, and Consumer electronics) that mandate completely halogen-free materials.

2. Общие технические требования к печати

Тип чернил 1-Component (Convertible to 2-Component via Hardener)
Глянцевая отделка Глянцевый
Плотность сетки экрана ≤ 350 mesh/inch

3. Серия «Цвет»

The PET-4600 series features pure transparent tints that are exceptionally easy to custom mix. A key advantage of this formulation is that it resists color mottling and floating when different tints are blended.

  • Красные оттенки: T-10 Bright Red, T-13 Purple-Red.
  • Жёлтые оттенки: T-20 Light Yellow, T-21 Deep Yellow.
  • Blue & Green Tints: T-31 Blue, T-40 Green.
  • Другие оттенки: T-50 Purple, T-60 Black.
  • Transparent Base: T-70 Clear Varnish.

4. Инструкции по смешиванию и приготовлению

Выбор разбавителя: 10-3500 (Standard Thinner), 20-3500 (Slow-Dry Thinner).

Option A: 1-Component Processing

Формула смешивания 100 parts Ink + 15 to 30 parts Thinner.
Сушка на воздухе (25 °C) Высыхание на ощупь: 10–20 минут. Полное высыхание: 24–48 часов.
Принудительная сушка (выпечка) Touch Dry: 3-5 minutes at 90°C. Hard Dry: 10 minutes at 90-100°C.

Option B: 2-Component Processing (High Performance)

To significantly enhance adhesion, surface hardness, and abrasion resistance, convert the ink to a 2-component system by adding B-5 Hardener or the reinforced Отвердитель B-11.

Формула смешивания 100 частей чернил + 10 to 15 parts Hardener + 15 to 30 parts Thinner.
Срок годности (время, в течение которого можно использовать) 5 to 8 hours at room temperature. The ink will gradually thicken into a gel thereafter.
Сушка на воздухе (25 °C) Must air dry for a minimum of 48 часов to achieve cross-linking.
Принудительная сушка (выпечка) 90°C - 100°C for 30 minutes, OR 60°C - 70°C for 90 minutes.
Important Process Notes:
1. Adding hardener will slightly increase the overall gloss level of the dried ink layer.
2. Hardeners are extremely sensitive to atmospheric moisture; seal the hardener container immediately after opening to prevent gelation.
3. Forced baking generally yields superior and more stable physical properties compared to natural air drying.
4. Do not intermix PET-4600 with other ink series to avoid adverse chemical reactions.
