Described are crimped acrylic fibers with a small diameter, a minimum aspect ratio (L/D) in the 20-50 range, and having a crimp of greater than about 3% so as to enhance the viscosity of polymers, resistance to gravity-induced slumping when applied to vertical surfaces, and mix stability, as well as provide matrix reinforcement and toughness. The crimped acrylic fibers are adapted to act as improved physical thixotropes in adhesives, sealants, coatings, paints, grouts, building materials and the like. |
