Vinamold® is a hot melt compound which is meltable compositions used for the preparation of flexible molds. It is an economic alternative to silicone rubber, polyurethane and rubber latex for casting concrete, gypsum, polyester resins.
Vinamold® is an established name within the industry due to the unrivalled quality and versatility. For over 30 years clients know and trust the brand named which is a cost effective material for recreating article in a variety of various materials (i.e. plaster, reconstituted stone articles, polyester, glass fiber laminates…).
A hot melt compound based on vinyl resins for making flexible molds. Suitable for casting polyester, plaster, epoxy, and phenol-formaldehyde resins. Vinamold is flexible, melts at 150-170°C, and pours at 140-150°C. The molds are waterproof, chemical-resistant, and unaffected by climate. They capture fine details and allow multiple casts before being re-melted and reused.
Vinamold can be melted using various methods including microwaves, but for best results, we recommend using thermostatically controlled melting equipment. This ensures the material melts consistently and correctly at a stable temperature. The material should reach a liquid state without any discoloration or smoke. If overheating occurs, as indicated by these signs, the material should be discarded.
After melting Vinamold, pour the molten material slowly and steadily to the required depth, ensuring a minimum coverage of 20mm. To avoid trapping air, it may be necessary to maneuver the assembly, allowing the liquid to fill all details; having an assistant can be helpful. Allow the finished mold to set for at least 8 hours before attempting to release it. For intricate or smooth surfaces, this process may take longer and should involve gentle manipulation rather than tools that could cut or tear the PVC. Minor imperfections, such as air bubbles or tears, can be corrected by carefully touching up with a hot blade. If needed, small pieces of Vinamold can be fused into the mold surface to fill any cavities that may form if not properly addressed.
When handling molten Vinamold, exercise extreme caution as it melts at temperatures above 150°C (302°F) and can cause burns. Avoid inhaling fumes during melting; although not toxic, the vapors from plasticizers can be irritating. Ensure adequate ventilation and extraction in the heating area to minimize discomfort and respiratory irritation.
