No Risk
Eco friendly hardener for emulsion screen printing, both for water and solvent resistant.
All materials are water-based.
It is applied to both sides of the screen after it is exposed, developed, blocked out, and dried.
The paint suction machine could easily suck off the hardener on the screen Screen remains reclaimable when all process techniques are followed .
Emergency Treatment
It is development by our own company, it is a brownish red flexible paint for protecting printing plate.
Contrast with the traditional product, our product(one-component) is more easier to use and save time.
Excellent flexibility, water resistance, solvent resistance and chemical resistance like acid, alkali and salt.
Protecting the sensitive-layer, made the printing plate more durability. With the emulsion hardener, the lifespan of the printing plate can be increased twentyfold.
Storage Stored in a shady and cool place, can be stored for 6 month in sealed barrel The paint hardener make strong adhesive with the photo emulsion and the stencil could not be damaged easily, also will make stencil removal more difficult.
Usage: Suitable for textile printing and large-batch printing, especially for blanket printing or which the meshes over 60 ;
