SHIELD TZ140

Primer:
Depending on your project, some will don't require a primer but requires a first coat example a surfboard, paddle, carbon fibre parts, etc. A coverage normally depends on the applicator but a good start for the first coat for parts is 150-200grams per sq.m.

For projects like countertops, you may use the SHIELD TZ140 as a primer. A coverage of 0.15kgs/sq.m to 0.3kgs/sqm is recommended but may still vary depending on your desired amount of application. This method will give your project the best quality result. Just use a roller or brush to spread and seal the concrete substrate. A white, grey or black colour pigment can be mixed with the resin for better priming colour. When cured, this epoxy primer can be sanded using 100grits sanding paper before the next coat. This is best applicable for surface protection on countertops, tables and smaller areas compared with a flooring project. For general flooring, parking, garage or warehouse, a thin layer of epoxy spread using a brush is enough without needing a sanding work for the next coat.

Mid Coat:
Mid coat or second coat for sports equipment or carbon fibre parts are very important. It is best to apply this coat when the first coat is still tacky dry otherwise like for large or difficult projects, you can wait for the first coat to be fully dry and just sand it using 80grits sandpaper then clean the surface before applying the second coat. This is the best time you apply the epoxy with your chosen pigment colour.

Again for countertops projects, SHIELD TZ140  can be used as your mid coat. This is the part where you do your artistic designs. Before pouring the mid coat, make sure you only mixed a maximum of 4% colour pigments per mixture(refer to no.2) so that it may not compromise the quality of the epoxy. Pour only when the primer is dry or tacky dry. A coverage of 0.6kgs/sq.m to 0.8kgs/sq.m is recommended during this stage. Spread evenly and repeatedly using a trowel, roller or brush. The aesthetic appearance of your project depends on this part of the application. For countertops and table projects, a heat gun can be used to pop the bubbles at the surface or even plumbers torch but not recommended due to the risk of explosion especially when the user is not a qualified plumber.

Top Coat:
To further protect the final surface of the project, apply one last layer of clear SHIELD TZ140. Again, apply when the previous coat is tacky dry, otherwise, wait for it to fully cure then sand with 120grits sandpaper then clean again before applying the final coat. Pop the bubbles using a heat gun. A coverage of 0.4kgs/sq.m to 0.6kgs/sq.m is recommended for the final coating. 

Transparent masking:
If the desired result is clear or transparent, a primer and a mid coat without any pigment could do the job since SHIELD TZ140 is crystal clear when dried. The applicator can adjust the desired coverage while the same principle and application practice should apply.

Aside from being good abrasive protection because of Shore D hardness of 90, Onyx' SHIELD TZ140 also features very good anti-yellow properties because it is also UV resistant. It can also protect the surface from the heat of up to 140deg.C. It also inherits other special attributes from SURFACE Z90 like good self-levelling properties - thanks to its low viscosity that made this possible, high strength with natural defoaming and can be cured under room temperature or can be heated for faster curing time. It is also moisture proof making it best for masking and potting electronic components. When cured, SHIELD TZ140 is transparent and shines like a clear crystal with no corrugation since it also has a very good air release. 

All Onyx' Epoxy Resins "Z" Series (including CASTING Z85 & SURFACE Z90) is made from non-toxic and tasteless raw materials imported from Germany and Japan, thus producing a very stable none volatile resin with zero fumes that are safe for home use. The Median Lethal Dose or LD50 value of Onyx Epoxy Resins is >3000 mg/kg which is the same LD50 value of tease spoon of salt or sodium chloride. Note: Although SHIELD TZ140 is a safe product, it is still an industrial product, not food and therefore, should never be swallowed. In case this happens, immediately go to the hospital for medical attention.

Onyx Epoxy Resins are safe for home use and are none volatile, but strict safe work practices are still required.
1. Skin irritation varies from person to person, that is why when working with epoxy resins, always wear protective equipment like gloves, apron, shoe cover rugs, spiked booties or even a disposable coverall to avoid direct skin contact especially when mixing, pouring and spreading on a large work. In case skin contact happens, immediately rub with a clean towel or paper then thoroughly wash with water and soap. Do not clean your skin with cleaning solvents like thinners, acetone, mineral spirits, etc. since these chemicals can penetrate your bare skin.
2. Work in a very well ventilated space and always wear a mask. For poor ventilation and tight working areas, a respirator is required to reduce and/or even eliminate any health risks. Some will smell the resin, some don't. Most people identify the smell as the fumes but they're not the same. Onyx Epoxies are very stable during the reaction and no VOC or fumes is vaporized during the reaction, but continuous, repeated and long term exposure still may cause irritation to the respiratory tract.
3. Use protective goggles or even a face shield to keep your eyes safe especially during sanding and even from accidental contact of the epoxy resin with your eyes. Epoxy can cause eye irritation and swelling. In case this happens, don't rub instead continuously wash with running water for 15 minutes and seek medical attention immediately.
4. Do not swallow this product. Immediately seek medical attention if this happens.
5. Test first this product with a small amount of mixture to minimize mistakes during the actual work.
6. Keep out of reach of children.
