UreCoat™ Matting Powder /300 gr

UreCoat™ Matting Powder is dissolved in solvent (99% isopropyl alcohol or acetone) and then mixed with UreCoat™ Urethane to create a coating that can be applied to a variety of surfaces to eliminate gloss or shine. Coating can be brushed or sprayed using an HVLP spray gun onto some surfaces to create a lasting matte finish. Compatible surfaces include Smooth-On flexible urethane elastomers, urethane foams and epoxies.


Features

Use this system to create matte surface finishes on artificial vines, tree branches or bark, rocks, etc. for themed environment effects. It is also suitable for creating a matte finish on movie and cosplay props, costume elements, animatronic skins, taxidermy, latex mask repair and more. In addition to providing a matte finish, the cured UreCoat™ coating is highly water, impact, ultra-violet and abrasion resistant.

Safety - Store and use all materials at room temperature 23°C. This product has a limited shelf life and should be used as soon as possible. Powder should be kept as dry as possible to minimize chance of moisture reaction with urethane. Keep containers air-tight closed when not in use. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question. Wearing a NIOSH respirator is required when using this product.

Read the UreCoat™ technical bulletin prior to using. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Because this product is mixed with either alcohol or acetone solvent, use only in a properly ventilated area and wear a NIOSH respirator. If spraying, a Tyvek® suit with independent air supply is recommended.

WARNING - FLAMMABLE: Keep solvents and solvent mixtures away from all ignition sources.

PROCEDURE - You must use an accurate gram scale to be successful. You will first measure and mix Matting Powder with solvent. You will then add this mixture to UreCoat™, mix all components and apply.

MEASURING & MIXING...

When measuring, use an accurate gram scale. The following chart provides an example ratio for a brushable mix. For best results, use new, clean 99% isopropyl alcohol or acetone to dilute Matting Powder mixture.

UreCoat™ Matting Powder 10 parts - 99% Isopropyl Alcohol Or Acetone 200 part - UreCoat 00 Parts A | 10 Parts B - Pot Life 30-45 min. - Cure Time 24 hours

STEP 1. MEASURE AND MIX SOLVENT AND MATTING POWDER - Due to flammability of solvents, we recommend hand mixing only with flat edge wooden paint stirring stick. Sift proper amount of UreCoat™ Matting Powder into solvent and mix thoroughly. Important: Be sure to scrape the sides and bottom of the mixing container several times while mixing.

STEP 2. MEASURE AND MIX URECOAT™ - Read technical bulletin for UreCoat™ and follow instructions. After dispensing proper amounts of UreCoat™ into a mixing container, mix thoroughly for 2 - 3 minutes using a square edged mixing stick. Aggressively scrape the sides and bottom of the mixing container several times. Use the square edge of the stick to bring material off of the sides of the container and blend.

STEP 3. COMBINE MATTING POWDER MIXTURE AND URECOAT™ MIXTURE - After dispensing mixed UreCoat™ and Matting Powder mixture into a mixing container, mix thoroughly for 2 - 3 minutes using a square edged mixing stick. Aggressively scrape the sides and bottom of the mixing container several times. Use the square edge of the stick to bring material off of the sides of the container and blend.

BRUSH ON APPLICATION...

Apply In Thin Layers By Brush - Use a disposable chip brush or foam brush to apply material with UreCoat™ added. Apply a thin layer to the surface, minimizing the brush strokes. Wait 30 minutes (at 23°C) for material to partially cure and apply another layer if needed. Do not let previous layer fully cure if applying another layer as delamination between layers may result.

MEASURING AND MIXING FOR SPRAY APPLICATION USING HVLP SPRAY GUN...
When measuring, use an accurate gram scale. The following chart provides an example ratio for a sprayable mix For best results, use new, clean acetone to dilute Matting Powder concentrate.

UreCoat™ Matting Powder 10 parts - Acetone 400 parts -UreCoat 100 Parts A | 10 Parts B 45 min-Pot Life 45 min- Cure Time 24 hours

STEP 1. MEASURE AND MIX ACETONE AND MATTING POWDER - Due to flammability of solvents, we recommend hand mixing only with flat edge wooden paint stirring stick. Sift proper amount of UreCoat™ Matting Powder into solvent and mix thoroughly. Important: Be sure to scrape the sides and bottom of the mixing container several times while mixing. The use of a strainer, such as a cone funnel strainer (190 micron) is recommended after mixing Matting Powder with the solvent.

STEP 2. MEASURE AND MIX URECOAT™ - Read technical bulletin for UreCoat™ and follow instructions. After dispensing proper amounts of UreCoat™ into a mixing container, mix thoroughly for 2 - 3 minutes using a square edged mixing stick. Aggressively scrape the sides and bottom of the mixing container several times. Use the square edge of the stick to bring material off of the sides of the container and blend.

STEP 3. COMBINE MATTING POWDER MIXTURE AND URECOAT™ MIXTURE - After dispensing mixed UreCoat™ and Matting Powder mixture into a mixing container, mix thoroughly for 2 - 3 minutes using a square edged mixing stick. Aggressively scrape the sides and bottom of the mixing container several times. Use the square edge of the stick to bring material off of the sides of the container and blend.

SPRAYING - Use an HVLP spray gun with a nozzle size of 1.4 mm. Pour mixture into HVLP gun canister and spray in a thin layer. Wait 30 minutes (at23°C) for material to partially cure and apply another layer if needed. Do not let previous layer fully cure if applying another layer as delamination between layers may result.

CURING...

After application of final layer, let all layers cure for at least 24 hours at 23°C before handling. Adding UreCoat™ Matting Powder slows the pot life and cure time of these materials. Material may appear “dry” but will remain tacky until fully cured and can be easily marred, overworked, or displaced if handled during this tacky state.
