3M™ AC-665C12 Aerospace Sealant 70005203636, 3.5 oz cartridge

3M™ AC-665C12 class C fay surface aerospace sealant is ideal for offering effective barrier against the common causes of corrosion. This product comes in two parts which includes part-A catalyst and part-B base. The liquid part-A catalyst is black in color, while the thixotropic paste part-B base is yellow in color. This slight odored part-A catalyst has a specific gravity of 1.97 and VOC contents of 0 grams per liter. This aromatic odored part-B base has a specific gravity of 1.46 and VOC contents of 53.9 grams per liter. The sealant is supplied in a 3.5-ounce cartridge and can be mixed in a 100 base/10 catalyst ratio by weight to form a mixed compound. It requires 12 hours for application and will be sufficiently cured after 14 days. The product withstands a service temperature range of -65 to 250 degrees F.

Features:

• Standard cure rate helps to meet various process demands
• Efficiently maintains flexibility and bond strength on various metals
• Employs corrosion inhibiting formula and meets multiple aerospace material specifications
• Easy to apply using spatula, extrusion gun or injection dispenser
• Density of 1.97 grams per milliliter for part-A catalyst and 1.46 grams per milliliter for part-B base
