Polytek® NaturForm™ 74 Molding Latex Rubber is a high solids (70-74%) natural latex with excellent tear strength and elongation properties. To make a mold, multiple layers of this latex are brushed (spray application is not recommended) onto an original model to form a tough rubber blanket mold (each layer must dry before the next layer is applied). These thin molds are typically backed with a supportive mold shell.
Molds made with natural latex are often used for casting plaster, concrete (e.g., veneer stone manufacturing and statuary) and limited casting with some resins.
NOTES: Exposure to temperatures <40°F and >80°F may damage latex, causing irreversible coagulation. DO NOT ALLOW TO FREEZE. Always store and use at room temperature.
SHIPPING: Latex cannot be shipped in temperatures near or below 32°F. Expedited Shipping Service is available at an additional cost, but cannot be purchased online. Please call Polytek Customer Service (1-800-858-5990) for more information.
