In this segment of the video, the presenter begins by discussing the three main categories of epoxy resins: highly viscous resins for coating surfaces like Honey resin, low viscosity resins for penetrating materials and layering, and UV resins for specialized uses like jewelry making. The importance of industrial safety when working with epoxy resin is emphasized, including the need for proper ventilation, wearing a breathing mask during sanding and mixing, and following safety instructions for health.
00:03:00
In this segment of the video, the key safety precautions for working with epoxy resin are emphasized. It is recommended to wear long clothes to avoid skin contact, use suitable gloves made of Butyl or nitrile, wear goggles when mixing larger quantities to prevent splashes that could harm the eyes, and ensure that any spills on the skin are washed off immediately. It is also advised to seek medical attention if resin comes into contact with the eyes and to wear protective goggles to prevent such incidents. The video also discusses the two options for casting molds: purchasing ready-made silicon molds or building a mold using materials like wooden boards or acrylic glass, ensuring the mold is waterproof to prevent resin leakage.
00:06:00
In this segment of the video, the speaker emphasizes the importance of properly preparing the mold before pouring resin. They discuss sealing holes and coating the mold’s inside to prevent resin sticking. Tips include using adhesive tape, parcel tape, or a wax-based release agent spray. The pouring height is crucial, with overheating a risk if exceeded. It is recommended to check the resin manufacturer’s guidelines for pouring height. The segment also touches on the tools needed for mixing resin, suggesting the use of a silicone pad for frequent epoxy resin users.
00:09:00
In this segment of the video, the focus is on the preparation and mixing of epoxy resin. The key points highlighted include the need for silicone mats for easy cleanup, the use of disposable plastic cups for mixing, the importance of a precise scale for accurate mixing ratios, and the ideal room temperature for working with epoxy resin (20-22 degrees Celsius). Emphasis is placed on the two-component nature of epoxy resin, with resin and hardener components needing to be mixed in the correct ratio (e.g., 2:1) by weight. Details on different resin types and their specific mixing ratios are mentioned, emphasizing the importance of following product instructions for optimal results.
00:12:00
In this part of the video, the speaker emphasizes the importance of maintaining the correct mixing ratio of resin and hardener when working with epoxy resin. They highlight the need to promptly reseal packages to prevent hardeners from reacting with ambient air. The video also discusses different options for coloring epoxy resin, such as dry pigments, pigment pastes, and alcohol colors. The speaker advises adding colors in small quantities to avoid compromising the hardening process. Exploring color options and being creative can lead to interesting color shades.
00:15:00
In this part of the video, the focus is on casting epoxy resin. Key points include ensuring the resin does not exceed the maximum pouring height, allowing time for each layer to harden before adding another, utilizing wet-in-wet casting for better bonding between layers, and sanding the surface if needing to add another layer after hardening. It is recommended to use higher viscosity resins for projects involving greater depths to allow for a one-time pour. Tips are provided for avoiding air inclusions and bubbles, such as pouring resin slowly from a low height and starting at the lowest point of the mold for even spreading.
00:18:00
In this segment of the video, the speaker discusses the use of epoxy resins with long drip times that help air bubbles rise and escape. To remove surface air bubbles, a hot air dryer or a Bunsen burner can be used carefully. A tip is given to apply epoxy resin on wood followed by drying to prevent air bubble issues. After curing the epoxy resin for about seven days, the next steps involve grinding and polishing the surface in three stages: rough grinding, fine grinding, and polishing with specialized pads. Various grit sizes of sandpaper are recommended for each stage of sanding, with a tip to soak the paper before use to prolong its lifespan. The process is described in detail to achieve a smooth and clear surface finish.
00:21:00
In this segment of the video, sandpaper is highlighted as a key tool to remove dust from the surface to prevent scratches. The process involves using a polishing paste with a microfiber cloth to close microscopic scratches and achieve a smooth finish. Polishing and grinding are emphasized as essential steps before concluding epoxy resin processing. The viewer is encouraged to feel confident and ready to work with epoxy resin. The video wraps up by inviting feedback, suggesting subscribing for future projects, and expressing gratitude to the audience.
