NU-clear
Features
• Superior scratch and slip resistance
• Superior water resistance
• Lower temperature film forming and curing
Overview
NUcoat NU-clear is a gloss UV stable single component water based clear coat system which incorporates unique self-cross linking chemistry that improves the chemical and scratch resistance of the product.
NUcoat NU-clear is compatible with most UV cured and solvent based inks with a very wide media compatibility. It adheres well to PVC and many other rigid substrates.
NUcoat NU-clear has low blush or colour shift once applied to printed images and has good flow and levelling properties. It is possible to apply a second coat of NUcoat NU-clear over the first coat, once it has dried.
NUcoat NU-clear is ideally suited for use on self-adhesive vinyl, flexible, as well as certain rigid substrates requiring additional durability, as well as scuff and chemical resistance. For optimum results, ensure a dried film thickness of approximately 20 microns, which will result in an approximate coverage of 20 square meters per litre.

INSTRUCTION GUIDE
The NU-clear gloss coating produced by NUtec Digital Ink is designed to be applied in a liquid form and once cured, will aid in the general protection of prints from the elements and application procedures.
APPLICATION OF NU-clear
There are three main methods to apply a liquid laminate/coating:
| 1. | By hand using a paint pad |
- Before applying each stroke be sure
to wipe excess liquid coating into tray - Apply on level horizontal surface
- Testing application stroke patterns for
your best result is advised - Steady even strokes are essential to
maintain even liquid layer thickness
| 2. | Airless spray gun or airbrush tool |
- Using either a spray gun or
airbrush tool allows for control of
layer thickness like any paint
application - Thicker layers result in a glossier
finish - Thinner layers can help achieve a
satin finish - Apply on level horizontal surface
- It will often help to add an extra 10%
water to dilute the mixture to improve
the performance of the spray gun - Make sure the equipment is
thoroughly cleaned after use
| 3. | Automated Mayer rod/ bar application machine |
- Consult the manufacturer’s guidelines
for the machine settings - Perform tests to check the drying and
gloss levels
DRYING OR CURING
The three application methods will have slightly different drying or curing characteristics:
| 1. | By hand using a paint pad |
- It is essential to allow the liquid coating to dry slowly to ensure bubbles release and the wet surface is allowed to spread and flatten evenly
- This should be done on a flat horizontal surface
- The environment should be as free of dust and dirt particles as possible
- Coating is usually ready to be handled after ONE to TWO hours after application but full curing will take 24 to 48 hours
- If available infrared heating lamps can be used to accelerate full curing but it is still advised to allow for layer to flatten and bubbles to release naturally prior to this
| 2. | Airless spray gun or airbrush tool |
- The thinner the layer the quicker the drying time
- Allow the layers to flatten and bubbles to release prior to any external heat or forced air drying
- Coating is usually ready to be handled after ONE to TWO hours after application but full curing will take 24 to 48 hours
- If available infrared heating lamps can be used to accelerate full curing but it is still advised to allow for layer to flatten and bubbles to release naturally prior to this
| 3. | Automated Mayer rod/ bar application machine |
- Use the machine guidelines to adjust the layer thickness, speed and drying energy to get desired result
- Full curing will still continue for up to 48 hours
