Quebec, Ontario · More info

The EM9300 Polycarbonate Urethane is an exterior/interior, non-yellowing clear water-based coating designed to allow exceptional adhesion to wood and engineered wood.

Engineered as a final topcoat for achitectural woodwork, doors, cabinetry, trims and other high-end applications which require a strong yet flexible coating under high UV exposure environments. EM9300 offers an excellent chemical resistance as well as an exceptional water resistance during vertical water exposure, such as rain.

The clarity and depth of the EM9300 Polycarbonate Urethane is phenomenal. If buffed to a high gloss using automotive or industrial buffing compounds, EM9300 will exhibit a crystal clear film without the plastic look usually associated with acrylic finishes.

How to use

Preparation: Architectural wood surfaces should be sanded with a minimum of 80-grit, low stearate content aluminum oxide sandpaper to remove mill glaze and any excess material. The final sanding schedule should be reviewed based on the desired final finish. A maximum of 320-grit is suggested.

For application to ferrous metals it is necessary to apply an anti-rust primer such as
Tremclad Water Based Rust Primer prior to application of EM9300.

Surface must be clean, dry and free of any contamination by moisture, grease, oil or dirt. Remove contamination with denatured alcohol and water mixed in equal parts. If heavy grease or oil is evident use a biodegradable wood cleaner to remove the contamination, then follow up with water/alcohol wash down. Wood substrates should be kiln dried and not exceed 10% moisture content

Application: The EM9300 Waterborne Polycabonate Urethane can be applied by brush, roller or spray method. Back brushing with a poly-bristle brush is recommended for applications onto substrates rougher than 180-grit sanding schedule to ensure even surface penetration and film formation. Product may also be applied with a lint free roller and then back brushed into the substrate. Spray methods include Conventional, HVLP, Air-Assisted Airless & Airless sprayers. Consult with your spray equipment manufacturer to determine the appropriate gun set and air pressures based on coating viscosity and intended use.

A minimum of 4 coats of EM9300 Waterborne Polycabonate Urethane should be applied to obtain a durable film formation. All coats should be applied at 3-4 mils wet per coat on a (rough) wood substrate sanded 80g. Each coat should be allowed to dry completely for 1 hour @ 20C before recoating. Application temperatures must be above 10C° and relative humidity below 80%. Do not apply coating to substrates where the moisture content is over 10%. Excess moisture may cause film clouding, adhesion problems and premature film failure. Do not apply coating to exposed areas when rain is forecast or imminent within 24 hours.

Target Coatings EM9300 Waterborne Polycabonate Urethane can be tinted with water-soluble universal colorant and water-soluble dyes. Test each tinting method to ensure proper film formation and adhesion prior to commencing with the entire project.

Maintenance

The expected life cycle of EM9300 will vary based on UV, moisture and ambient pollution exposure. The key to long-term substrate protection is periodic inspection and maintenance of this coating. Inspect the film formation qualities of this coating as it ages. Dulling, oxidation and film thickness reduction of the cured finish is a sign that the coating is breaking down.

A periodic cleaning and re-coating should occur when any of these physical signs begin to appear. Wash the effected surface with a biodegradable wood surface cleaner to remove all surface dirt and inspect for film adhesion integrity. If adhesion of the coating is acceptable, lightly abrade the surface to be recoated with a medium grade 3M Scotch-Brite® pad and rinse off residue with fresh water. Allow the surface to dry and apply 2-3 coats of Target Coatings EM9300 Waterborne Polycabonate Urethane as specified above. If the existing film formation is deteriorated beyond surface recoat repair, power-wash the remaining film formation off of the substrate and prep the surface for complete refinishing.

Freeze/thaw stability

Avoid too many freeze-thaw cycles. If the product has frozen, allow the product to thaw at room temperature for 48 hours without stirring.
