Abstract

A composition for a snow- or ice-accretion inhibiting member which has a static friction coefficient of less than 1.3 relative to snow having a temperature range of 0 to -10.degree. C. The composition of the present invention can show not only a good snow- or ice-accretion inhabiting property upon snowfall but also an improved snow slipping-off property upon temperature rise.
