Seal canvas with ClearShield® Type C
Water based liquid laminate for the Fine Art and Giclee industries and especially inkjet printed canvas.
Water resistant canvas applications (highly flexible). suitable for micro porous ink jet receptive substrates to help reduce or eliminate pinholes.
ClearShield® Type C is the ideal coating for Giclee canvas applications. It exhibits the flexibility required for stretching canvas with no cracking of the clear coat. Clearshield laminate is formulated to work on micro porous and porous ink jet receptive layers. It reduces or eliminates pinholes normally encountered when applying Liquid Laminates to ink-jet coated canvas. Type C is formulated to be used over water-resistant canvas printed with pigmented inks and can be applied with most application techniques including hand roller, spray gun and automated equipment.
Here’s a video on how to apply Clearshield with a roller:
Clearstar’s liquid laminates are ideal for large volume customers using liquid laminators such as the
StarLam 1600R. The StarLam 1600R is a 64” roll to roll liquid laminator that is easy to operate and applies a smooth even layer of ClearShield laminate over a wide variety of substrates.
Technical Information ClearShield®
We generally recommend the following dry film thickness:
ClearShield Water-based Clears- .7 to 1 mil dry film
This chart shows you the theoretical coverage at 100% transfer efficiency.Fine Art versions tend to penetrate much more than standard versions so the surface film build will be lower, yet the protection will be excellent.
1 mil dry. 5 mils dry
ClearShield (all products) 480 sq. feet 960 sq. feet
Roll and mop applications transfer at 100% efficiency.
Conventional spray applications transfer at 35% efficiency.
HVLP spray applications transfer at 65% efficiency.
We believe in testing.
As the digital industry grows and more inks and media types are introduced, it is now impossible to predict the compatibility of every combination of media, ink, and clear coat. We strongly recommend that you test before use. A test will immediately show you incompatibilities,including water sensitivity, ink jet receptive layer mud cracks, and ink bleeds.
Generally, let the tested material dry for at least 24 hours. Evaluate the adhesion, flexibility, and visual appearance.
Be realistic in your expectations and simulate the conditions the material will be exposed to.
