Available in multiple work lives, with rapid cure times, AC-350 increases your workflow flexibility.
- Mixing the Class C version results in a flowable, faying surface grade material that is easily applied by brush, roller, spatula, or extrusion gun. Application and assembly times vary by product, allowing you to design flexibility into your workflow processes.
- When used together, the Class A, B and C variants are ideal for sealing and/or repairing integral fuel tanks and sealing fuselages.
