Sound damping plaster compsn. - of quartz sand and poly-satd. polybutadiene binder

摘要

Plaster comprises a mixture of 97wt.% quartz sand of which half has a particle size of 0.063-0.25mm and half has a particle size of 1.25-2mm and 3wt.% of a bonding agent which is a polyunsatd. polybutadiene. USE/ADVANTAGE - The plaster has hollow spaces giving it good compression strength, flexibility and ability to suppress the sound of feet making it useful as a covering for underfloor heating apparatus.
