Customer Questions & Answers
-
Question:
What is the BJB - Rigid 78SHORE D Urethane Casting System used for?
Answer: The BJB - Rigid 78SHORE D Urethane Casting System is designed for creating durable, rigid castings with exceptional dimensional stability. This is ideal for applications such as prototypes, molds, and industrial parts. The formulation offers high tensile strength and resistance to impact, making it perfect for projects that require both resilience and precision. -
Question:
What are the key features of the TC-808 A/B system?
Answer: The TC-808 A/B system features a 78 Shore D hardness, providing a tough and wear-resistant finish. It has a low viscosity, which facilitates easy mixing and pouring, ensuring smooth flow into molds. Additionally, its quick curing time makes it an efficient choice for production runs, allowing users to produce consistent parts rapidly. -
Question:
Can I use the BJB TC-808 Urethane for outdoor applications?
Answer: Yes, the TC-808 Urethane Casting System can be used for outdoor applications when properly formulated. Its resistance to moisture and UV light makes it suitable for items exposed to the elements. For best results, consider using a UV-resistant coating on finished pieces that will be regularly outdoors. -
Question:
How do I mix the TC-808 A/B components correctly?
Answer: To mix the TC-808 A/B components, first ensure both parts are at room temperature. Using a clean mixing container, combine equal parts by weight of the A and B components. Stir thoroughly for at least two minutes, scraping the sides and bottom to ensure an even blend. Mixing correctly is crucial for achieving optimal performance and cure. -
Question:
What safety precautions should I take when using this casting system?
Answer: When working with the BJB TC-808 system, it's important to use appropriate personal protective equipment (PPE). This includes gloves, goggles, and a mask to avoid any skin or respiratory irritation. Ensure you work in a well-ventilated area to minimize inhalation of fumes. Following these precautions will help ensure a safe working environment. -
Question:
Can the hardened urethane be painted or finished?
Answer: Yes, the cured urethane from the TC-808 system can be painted or finished to achieve the desired aesthetics. Before applying paint, sand the surface lightly for better adhesion. It’s advisable to use paints suitable for plastic or urethane materials to ensure compatibility and durability in the finish. -
Question:
What is the pot life of the TC-808 A/B mixture?
Answer: The pot life of the TC-808 A/B mixture typically ranges from 30 to 45 minutes at room temperature. During this period, the mixed material remains workable enough for pouring into molds. Monitor ambient conditions, as temperature and humidity can influence this timeframe, affecting the mixture’s potency and curing speed. -
Question:
Is this casting system suitable for jewelry making?
Answer: Yes, the BJB TC-808 system is suitable for jewelry making, especially for creating durable molds for casting various materials. Its fine detail capture capabilities allow for intricate designs, and the resulting pieces are robust enough for wear. The low viscosity also works well for capturing fine details of the original model. -
Question:
How do I clean tools used with this casting system?
Answer: To clean tools used with the BJB TC-808 system, it’s best to do so before the product fully cures. Use a solvent such as acetone or a designated urethane cleaner to wipe the tools and containers. Cleaning promptly helps prevent residue build-up, ensuring that your tools remain in good condition for future projects. -
