Loop lock pull (N)
In the lab, the carpet backing adhesive is prepared by slowly mixing
the SBR latex, dispersant, sodium lauryl sulfate, and a nonionic
polybutene emulsion. The calcium carbonate is added while mixing, and
the tetrapotassium pyrophosphate is added to bring the visocsity into
the range of 16,000-20,000 cps. The mixture is frothed using high speed,
approx. 5 min.
