Coating & adhesion sciences, matched to the job
Two sciences decide print quality: the ink-receiving coating that locks ink at the surface, and the adhesion system that keeps the graphic in place and residue-free. ZST engineers both to the surface, the ink and the campaign lifecycle — from photo-lab coatings to fully adhesive-free reusable films.
The coating makes the printAn ink-receiving layer engineered for each ink chemistry — the most important technology behind every ZST medium.
A print medium is only as good as its coating. ZST's coating technology locks ink at the surface for vivid colour and sharp detail, cures it fast for instant-dry, smudge-free handling, and seals it for water resistance and outdoor durability. By formulating the coating to the ink — water-based dye and pigment, Eco-solvent, UV, Latex, HP Indigo and toner — we guarantee consistent output across every major print system.

Ink-Receiving Coating Science
SCITOP Coating · all media
Every ZST media carries a micro-porous, ink-receiving coating tuned to the printing process. The coating's open pore network wicks the ink droplet in by capillary action, locks the pigment or dye inside the layer, and leaves the surface dry in seconds — so dots stay crisp, colours stay vivid, and neighbouring colours never bleed into each other.

Gecko-Toe Biomimetic Adhesion
FreePost® Wall Lizard™ · WL Series
SCITOP's patented gecko's toe pad cling technology — a non-static, non-traditional adhesive design. The film clings to most clean and smooth surfaces and leaves absolutely no residue when removed, even after long application period.
- Application
- Dry apply
- Peel strength
- 10–150 g/25mm
- Reusability
- Removable, repositionable & reusable
- Best for
- Indoor & outdoor, short and long term
- Gecko's toe pad design
- Non-static, non-traditional adhesive design
- Bubble-free, easy and quick to install
- No residue on application surface
- Removable, repositionable and reusable
Micro Suction
FreePost® Octopus™ · OT Series
Powered by SCITOP's patented octopus micro suction technology — the film clings to clean, smooth and flat surfaces without chemical adhesive, and can be repositioned and reused.
- Application
- Dry apply
- Peel strength
- Adhesive-free micro suction
- Reusability
- Reusable & repositionable
- Best for
- Indoor promos, window ads, labels
- Bubble-free
- Easy and quick to install
- Removable, repositionable and reusable
- No residue for indoor application within shelf life
Vacuum Suction (Adhesive-Free)
FreePost® Easy Cling™ · EC Series
Innovative cling technology: it doesn't rely on chemical adhesion, magnetic force or static — it clings onto glass and other smooth surfaces easily by using vacuum force. So it is low-tack and will not leave adhesive on the applying surface.
- Application
- Wet apply recommended
- Peel strength
- 2–10 g/25mm
- Reusability
- Removable, zero residue
- Best for
- Glass & smooth surfaces, windows
- Non adhesive design
- Adhesion using vacuum technology
- No residual on application surface
- Designed for window and smooth surface application
Dot-Pattern Adhesive
FreePost® Spider™ · SP Series
Dot shaped removable adhesive on one side with liner — the dot pattern allows air to escape for a bubble-free application, and the adhesive stays removable for short term indoor use.
- Application
- Dry apply
- Peel strength
- Removable dot adhesive
- Reusability
- Removable for short-term use
- Best for
- Short-term indoor events & promos
- Dot shaped adhesive design
- Bubble free, easy and quick to install
- Can be applied to most surfaces
- PVC Free, environmental friendly "green" material (PET & PP models)
Strong Adhesive
FreePost® AC™ · AC Series
A strong adhesive layer on one side with liner, designed for desktop water-based inkjet printing. PVC free.
- Application
- Dry apply
- Peel strength
- 1000–1500 g/25mm
- Reusability
- Permanent-leaning hold
- Best for
- Window & decorative stickers, short or long term
- Can be applied to most surfaces
- PVC free. Environmental friendly "green" material
- Good dimensional stability, good weather resistance, suitable for short-term or long-term applications
- Strong adhesive
