I. Core Material for Simulated Dinosaur Skin

The reason why simulated dinosaur skin can achieve a realistic appearance and soft touch lies in its core material: glass glue — a type of silica gel, scientifically named silicone sealant, with silicon as its main component. In actual production, the industry generally uses Type B silica gel as the base material for the skin. Its key advantage is excellent stretchability, which can perfectly adapt to various movement ranges of simulated dinosaurs, avoiding cracking during movement. This is also the core prerequisite for ensuring the texture and durability of the skin.

II. Main Classifications of Glass Glue

Glass glue is not a single type. According to its composition and purpose, it can be divided into two major categories, and the characteristics of different types also meet the production needs of simulated dinosaur skin:

Silicone glue: Further subdivided into acid glue, neutral glue, structural glue, etc. Among them, neutral glue and structural glue have better adhesion and weather resistance, making them the mainstream choice for simulated dinosaur skin;Polyurethane glue (PU): Divided into adhesive glue and sealant, which are used as auxiliary materials in some scenarios to enhance the fit between the skin and the internal skeleton.

III. Core Advantages of Glass Glue as Dinosaur Skin Material

Superior Weather Resistance: It has excellent ozone resistance and UV resistance. Even when exposed to outdoor environments for a long time, it can effectively resist wind, sun and rain, extend the service life of the skin, and avoid fading and aging;Wide Bonding Range: It can firmly bond with various substrates such as metal, glass, aluminum, ceramic tiles, acrylic, concrete, and wood. Without the need for additional primers, it can achieve tight connection between the skin and the internal skeleton and filling materials of the dinosaur;Excellent Physical Properties: It has strong adhesion, high tensile strength, and good vibration resistance, moisture resistance and odor resistance. It can adapt to environmental changes of alternating cold and heat, and will not become hard, brittle or cracked due to temperature fluctuations;Good Construction Adaptability: It will not flow due to its own weight, and can be used for joint treatment of any part of the simulated dinosaur such as the top and side walls, avoiding sagging, collapsing or sagging, and ensuring the flatness of the skin surface.

IV. Optimization and Upgrade of Skin Performance

To further improve the tensile strength and service life of the simulated dinosaur skin, elastic fibers are added during the production of glass glue. This optimized design greatly enhances the toughness of the skin without damaging the original elasticity and soft texture of the silica gel. It effectively solves the problem of fatigue loss that may occur in pure glass glue after long-term repeated stretching, allowing the skin to maintain a "touchable and textured" experience while withstanding high-frequency motion simulation and extending the overall service life.
