How We Test Every Batch of Epoxy So You Get Superior Results

In this episode, the hosts visit iCoat’s offices to explore the rigorous quality control and production processes behind their epoxy resin products. The focus is on the steps taken to ensure every batch of resin is consistent, reliable, and meets high standards for both performance and safety. The discussion covers sourcing of raw materials, extensive testing protocols, batch retention for traceability, best practices for users, troubleshooting common issues, and the importance of maintaining controlled production environments. It’s no wonder iCoat is the clear industry leader in quality epoxy resin products.

Important Notes and Points:

• iCoat sources all raw materials from the United States to ensure quality and avoid issues associated with cheaper, less regulated imports from countries like India and China.
• Extensive testing is performed before, during, and after production, including drawdown and bubble release tests, to ensure batch consistency.
• Each batch is tested before bottling and again after bottling, with samples (retains) kept for at least a year and records maintained for up to five years for traceability.
• Testing includes casting samples in various molds to check for bubble release and clarity without using vacuum chambers or heat, relying on the resin’s natural properties.
• Production and testing are conducted in a controlled environment (72°F, controlled humidity) to minimize variables and ensure consistent results.
• Users are encouraged to replicate these controlled conditions in their own studios using heating mats, dehumidifiers, or air conditioning as needed.
• All epoxies will amber (yellow) slightly over time, but using high-quality, clean raw materials and UV-resistant additives minimizes this effect.
• iCoat’s products meet LEED Platinum standards and are food-grade/USDA approved, ensuring safety for food contact and environmental responsibility.
• Proper storage and prompt unboxing of finished pieces are important to prevent premature aging or yellowing of resin projects.
• Troubleshooting customer issues involves pulling retained samples from the relevant batch and recreating the customer’s conditions to diagnose problems, which are often due to user error such as incorrect mixing ratios or improper measuring tools.
• Maintaining accurate mixing ratios is critical; for their one-to-one epoxy, both parts must be equal by volume, not weight, as the components have different densities.
• Small deviations (up to 5%) in mixing ratios are generally acceptable, but larger discrepancies can cause curing issues.
• Warming resin before mixing (ideally to 80°F) reduces viscosity, making mixing easier and improving bubble release, but overheating should be avoided.
• Mixing techniques, such as using a drill mixer and ensuring thorough blending, are recommended for best results.
• The expected lifespan of a resin project depends on storage conditions and user handling; samples from as far back as 2019 still show excellent clarity and durability when properly stored.

This episode provides a comprehensive look at how iCoat maintains high standards in resin production and offers practical advice for both professionals and hobbyists to achieve the best results with their products.
