Handling Instructions: Weigh 100 parts of activator to 100 parts resin. Mix for a period of time until mixing is complete. Degas for 5 minutes under a vacuum of 25-29 inches of Mercury. Apply material. Cure according to the cure schedule desired. If dual cartridges are used, the material may be directly applied using a static mixer.
Note: Certain substances may inhibit the cure of Metasil 5060 by direct or indirect contact. Metallic salts, butyl, PVC plasticizers, chlorinated rubber, amines and sulfur containing materials may all inhibit the cure.
Storage and Handling: Mereco Metasil 5060 has a shelf-life of six months from date of shipment when stored in original unopened containers at a temperature below 25°C.
