Although many factors exist which will promote or inhibit adhesion of the acrylic paint onto the solid plastic, the most important element is the ability of the liquid to ‘wet-out’ the solid onto which it is painted. Lv 6. In this situation, the liquid is said to “wet out” or adhere to the surface. When paint runoff from an acrylic pour dries on a smooth surface, you can peel this paint off like dry dead skin after a sunburn. Did you know you can read answers researched by wikiHow Staff? wikiHow is where trusted research and expert knowledge come together. When the contact angle (θ) is large (greater than 90°), the liquid will tend to bead upon the solid indicating poor wetting. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The application of a tie-coat directly to the plastic’s surface may eliminate the need for a scuffing process which often results in visible scratch marks. 2. add paint to the ornaments.

When the contact angle (θ) is small (less than 90°), the liquid will tend to spread across the surface of the solid indicating good wetting. Acrylic Plastics (PMMA), ABS plastics and Polycarbonates are examples of polar plastics and therefore, typically have higher surface energy and improved adhesion for acrylic paints. Bond strengths and functional performance can be dramatically improved by increasing the water-loving (hydrophilic) and surface energy characteristics to promote adhesion, thereby adding value to the product and the process. The specialty primer can create a foundation that helps the paint stick. This can damage your brushes by fraying the bristles. Silanes are a popular class of adhesion promoters used if the plastic has appropriate functional groups. Surface contamination is the most common reason for premature coating failures.

Use magenta and cyan to tint the clear plastic of a police car’s bar lights.

For this to happen, either the surface tension of the substrate or the paint must break loose of the logjam in Figure 2. For models smaller than 1 foot (30 cm), a 1–2 in (2.5–5.1 cm) brush is appropriate. As you’re applying the paint, adjust your distance from the model based on whether or not you’re happy with the coverage of your spray paint.

Humidity and temperature degrade the treatment rapidly and it is imperative that the surface be coated within a short period of time, usually minutes. If you don’t cover the entire miniature, it will be difficult to clean, and you’ll probably have to soak it again. Purchase acrylic modelling paint at a standard arts and crafts store. ", "Good basic intro to paints and model painting. On plastics or metals, acrylic paint will only work if applied in between a sealing base coat and a top coat. Spray paint really only works if you need to apply large sections of color or add your base coat.

After you’ve dried your brushes, you can rub petroleum jelly on the bristles to preserve them. Unless polyethylene or polypropylene are specially treated (such as flame treatment), their surface energy is so low as to severely limit adhesion. Those would certainly include the acrylic, polycarbonate, polyester (PET), urethane plastics and some of the hard PVC Plastics. The more you practice though, the better you’ll get at it.

Flame treatment is used in treating PE, PP and PET. The sanded or etched surface will provide opportunities for the acrylic coating to find many small areas to attach to.
