MMAs are widely used for applications in aerospace, automotive, marine, composites, and transport. Because they cure quickly, they are often used in production lines. They are used for bonding metals including steel, stainless steel, and aluminum. They are used with composites including fiberglass and carbon fiber, unsaturated polyester, vinyl ester, gel-coat, sheet molding compound and epoxy. They are also commonly used with other thermoplastics like acrylics, acrylonitrile butadiene styrene (ABS), polycarbonates and polyvinyl chloride (PVC). Specific uses include:
