What is the substance on the skin of a decorative rat? - briefly
The outer layer consists of synthetic fur adhered to a preserved hide, typically sealed with an acrylic coating. This creates a glossy, decorative surface on the animal.
What is the substance on the skin of a decorative rat? - in detail
The exterior of a decorative rodent is typically treated with a protective coating applied after taxidermy or sculpting. The coating serves three functions: preservation, visual enhancement, and resistance to handling.
The most common substances include:
- Acrylic polymer resin – clear, UV‑resistant, dries to a hard, glossy finish. Applied in thin layers with a soft brush or airbrush.
- Nitrocellulose lacquer – fast‑drying, yields a high‑gloss surface. Often mixed with pigments for colored effects.
- Polyurethane varnish – provides a durable, matte or satin finish. Used when the piece must endure frequent contact.
- Silicone sealant – flexible, water‑proof, used on pieces with intricate details to prevent cracking.
When the rat is prepared by taxidermy, the skin is first cleaned, degreased, and treated with a preservative solution such as a diluted formaldehyde or phenolic resin. This stabilizes the tissue, reduces microbial growth, and makes the skin more receptive to the final coating.
Application steps:
- Preparation – remove residual moisture, smooth any imperfections with fine sandpaper.
- Primer – a thin layer of compatible primer (often an acrylic base) improves adhesion.
- Main coating – apply 2–3 coats of the chosen polymer, allowing each layer to cure fully (typically 15–30 minutes for acrylics, longer for polyurethane).
- Topcoat – optional clear varnish adds extra protection and enhances depth of color.
- Curing – store the finished piece in a dust‑free environment for 24–48 hours before handling.
Safety considerations: work in a ventilated area, wear gloves and a mask to avoid inhalation of volatile organic compounds. Disposal of excess material must follow local hazardous‑waste regulations.
The result is a stable, aesthetically pleasing surface that preserves the original texture of the fur while allowing the decorative piece to withstand display conditions.
