Customer Questions & Answers

  • Question: What is Smooth-Cast Onyx Slow used for?

    Answer: Smooth-Cast Onyx Slow is a high-quality urethane resin designed for creating beautiful, deep black castings. It's ideal for artists and hobbyists who require a strong, durable material for prototyping, sculpture, or unique crafts. The slow-curing aspect makes it perfect for intricate molds or projects requiring longer working times, allowing for greater detail and finesse in casting.
  • Question: How do I mix Smooth-Cast Onyx Slow?

    Answer: To mix Smooth-Cast Onyx Slow, combine equal parts of Part A and Part B by volume. Ensure you stir thoroughly for at least 3 minutes to achieve a uniform mixture. This resin has a specific mix ratio, and accurate measurements are crucial for optimal results. It is recommended to mix small batches to maintain better control over the working time and avoid excess material waste.
  • Question: What is the working time of Smooth-Cast Onyx Slow?

    Answer: Smooth-Cast Onyx Slow offers a working time of approximately 30 minutes at room temperature. This extended working time allows you to mold and shape your project without being rushed, making it suitable for more complicated designs. Note that temperatures can affect curing times, so always consider your workspace environment when planning your project.
  • Question: Can Smooth-Cast Onyx Slow be colored?

    Answer: Yes, Smooth-Cast Onyx Slow can be colored using urethane pigments or tints. This versatility allows artists to create unique projects by adding vibrant hues or custom effects. When adding colorants, it's important to follow the manufacturer's recommendations to ensure compatibility and maintain the integrity of the final cast.
  • Question: Is Smooth-Cast Onyx Slow food safe?

    Answer: Smooth-Cast Onyx Slow is not considered food safe once cured. While it creates a strong and attractive finish, it's important to avoid using this resin for items that will come into direct contact with food. If you need a food-safe alternative, consider using specific food-grade resins designed for such applications.
  • Question: What should I use as a mold for casting Smooth-Cast Onyx Slow?

    Answer: For casting with Smooth-Cast Onyx Slow, you can use a variety of materials such as silicone, plastic, or metal molds. Silicone molds are particularly popular due to their flexibility and ease of release, allowing for intricate designs. Ensure the mold is thoroughly cleaned and optionally treated with a mold release agent for easier demolding.
  • Question: Can I use Smooth-Cast Onyx Slow outdoors?

    Answer: While you can use Smooth-Cast Onyx Slow for outdoor projects, it's advisable to keep the curing process in a controlled environment. Direct sunlight and extreme temperatures can affect the curing and final properties of the resin. Once cured, you can use the castings outdoors, but consider applying a UV-resistant topcoat for protection against weathering.
  • Question: What safety precautions should I take when using Smooth-Cast Onyx Slow?

    Answer: When working with Smooth-Cast Onyx Slow, always use gloves, goggles, and a mask to protect against fumes and skin contact. Working in a well-ventilated area is essential for safety, as even low levels of urethane can cause irritation. Always follow the manufacturer’s safety guidelines for effective handling and application.
  • Question: How long does it take for Smooth-Cast Onyx Slow to cure completely?

    Answer: Smooth-Cast Onyx Slow typically cures to a hard state within 24 hours at room temperature. Depending on your project's thickness and environmental conditions, complete curing may take longer. It's best to avoid handling or demolding pieces until fully cured to ensure the best quality and strength.

    Answer: You can purchase Smooth-Cast Onyx Slow - Ultra-Black Urethane Resin - Pint Unit from Ubuy in Brunei. Ubuy offers a reliable option for obtaining this premium urethane resin, ensuring access to quality products that meet your crafting and artistic needs.

Smooth-On Molding & Casting Editorial Review

**** The Onyx-Slow casting resin has garnered a polarized set of reactions from users, marred by a mix of high expectations and disappointing experiences. Many customers appreciate the product for its decent finish and the ample working time it allegedly provides for multi-pour tasks. Stressing the advantages of ease in cold and resin casting, several users have highlighted the benefits of using the product when done correctly. However, these positive notes are overshadowed by striking criticisms regarding its inConsistency and poor reliability. Numerous customers report significant discrepancies with the advertised cure time, stating that it can take up to two to three hours longer than promised. This misinformation leads to frustration, especially for those familiar with similar products, who find themselves wrestling with an excessively short pot life and the need for meticulous mixing that seems almost excessive. Indeed, a fundamental misunderstanding of how to properly use Onyx-Slow appears prevalent among users—the notion that one can simply pour after a casual mix is quickly dispelled by the product's finicky nature. Unfortunately, many have faced disheartening experiences where their casting attempts failed to set correctly, resulting in a sticky, gooey mess rather than the intended solid form. Common feedback includes that a staggering percentage of attempts end with incomplete cures, contributing to a widespread impression that the product is ineffective. In essence, while Onyx-Slow holds promise through its initial appeal and familiarity with the Smooth-On brand, it falls prey to significant execution flaws that render it a less favorable option for both novice and seasoned users alike. **
