A substance, device, or treatment applied to prevent or slow the creeping (gradual deformation) of materials.
From anti- + creeper (agent noun of creep). This technical term emerged in materials science and engineering to describe protective substances used in construction and manufacturing.
Modern building codes require anticreepers in steel-frame buildings because uncontrolled creeping in hot climates once caused skyscrapers to literally sink—a invisible problem until buildings started collapsing.
