Use Recommendations
COBRA™ 521 has seen usage and success in the areas of core & mold making using chemical resin systems. The release will be affected by usage rates and intricacy of the core produced. Generally, the release agent can be applied using conventional spraying equipment such as an airless sprayer, a pressurized canister type sprayer or a molders siphon sprayer. In the latter instance it may be necessary to reduce the airflow in the inlet orifice of the container.
Since COBRA™ 521 is a non-flammable organic material, proper care should be taken when handling and applying this product.
