What is Epoxy Resin?

Epoxy resin is a versatile and popular material used in modeling and diorama projects for its remarkable properties and wide range of applications. It is a type of synthetic polymer that, when combined with a hardener, undergoes a chemical reaction to create a strong and durable material.

In the realm of modeling, it offers several benefits that make it an excellent choice for various applications. One of its key advantages is its exceptional clarity. The standard epoxy resin dries to a crystal-clear finish, allowing for the creation of transparent or translucent elements such as water effects, glass-like surfaces, or simulated liquids. This clarity adds a realistic and visually appealing touch to models and dioramas, enhancing their overall aesthetic appeal.

Another noteworthy characteristic is its excellent self-leveling properties. When poured or applied to a surface, it spreads out evenly, creating a smooth and level finish. This feature is particularly useful when creating flat surfaces, tabletops, or terrain elements in dioramas. Its self-leveling nature helps eliminate unevenness or imperfections, resulting in a professional and polished look.

This product also boasts exceptional hardness and durability once cured. It forms a robust and sturdy material that can withstand physical impact, making it suitable for creating durable components or surfaces. This durability ensures that any sort of encapsulations will remain intact even when handled or displayed over time, maintaining their quality and longevity.

Furthermore, this material, once cured, exhibits excellent chemical and moisture resistance. Once fully cured, it becomes highly resistant to chemicals, including solvents, oils, and household cleaners. This resistance protects models and dioramas from damage or discoloration caused by exposure to various substances. Additionally, this product is moisture-resistant, making it suitable for applications that require contact with water, such as creating water features, ponds, or streams in dioramas.

Additionally, It is known for its versatility in terms of coloring and customization. It can be easily tinted or pigmented using dyes for resins, allowing modelers to achieve a wide range of desired effects. Whether it's creating vibrant landscapes, replicating specific materials, or adding artistic touches, epoxy resin provides a versatile medium for expressing creativity.

Moreover, epoxy resin offers a wide window of working time before it begins to cure. This allows modelers and diorama builders to work on intricate details, complex structures, or multiple layers without feeling rushed. The extended working time ensures that every aspect of the project can be carefully executed, resulting in precise and refined final outcomes.

How to make an encapsulation with epoxy resin?

Creating an encapsulation with epoxy resin is a straightforward process that requires careful preparation and attention to detail. Here's a step-by-step guide on how to make an encapsulation:

1. Prepare the materials: Gather all the necessary materials, including mixing cups, stirring sticks, a silicone mold, and the items you want to encapsulate.
2. Set up a clean workspace: Ensure you have a clean and well-ventilated area to work in. Lay down a protective covering to prevent any accidental spills or damage.
3. Measuring: Follow the manufacturer's instructions to measure the appropriate amount of both components. Pour them into separate mixing cups in the recommended ratio.
4. Mix both components: Use a clean stirring stick to thoroughly mix them together. Stir slowly and methodically to minimize the introduction of air bubbles.
5. Let the mixture rest: After stirring, allow the mixture to rest for a few minutes. This will help any air bubbles rise to the surface and dissipate.
6. Pour the mixture into the mold: Slowly and evenly pour it into the silicone mold, ensuring that it covers the items you want to encapsulate completely. Take care not to overfill the mold.
7. Remove air bubbles: To eliminate any remaining air bubbles, gently blow on the surface of the resin or use a heat gun or torch on low heat, moving it evenly over the surface. Be cautious not to overheat or scorch the resin.
8. Allow to cure: Place the mold in a dust-free area and allow it to cure for 24 hours. The curing time can vary based on the specific product used and whether the mix is properly done, but it typically takes several hours or even overnight.
9. Demold the encapsulated item: Once it has fully cured, carefully remove the encapsulated item from the silicone mold. If needed, use a releasing agent or gently flex the mold to aid in demolding.
10. Finishing touches: After demolding, you may need to trim any excess resin or sand the edges for a smooth and polished finish. You can also apply a clear gloss varnish or polish the encapsulated item to further enhance its appearance.

How do flat epoxy resin edges? 

Achieving flat and smooth epoxy resin edges requires careful attention to detail and a few essential steps. Firstly, start by assessing the current state of the edges. If there are any irregularities or bumps, they will need to be addressed before attempting to flatten the surface. Use sandpaper with a grit of around 800 and continue with 1200 to gently sand the edges. Sanding in a circular motion can help ensure the even removal of any uneven areas. Be cautious not to apply too much pressure, as this may result in creating new unevenness or damaging the surrounding resin surface.

After sanding, thoroughly clean the edges to remove any sanding residue or particles. A lint-free cloth can be used to wipe the surface and ensure it is free from dust and debris. Once the edges are clean, apply a thin layer of epoxy resin over the entire surface, including the edges. The resin will help fill in any remaining unevenness and create a level surface. 

To achieve a truly flat finish, it may be necessary to repeat the process of sanding and applying a thin layer of epoxy resin multiple times until the desired result is achieved. Take care to allow it to fully cure between each layer. This process can help gradually build up a smooth and level surface on the edges.
