Choose from 711 high-viscosity through 719 ultra-high-viscosity according to pipe size and site conditions: high viscosity for small-bore thin-wall work, ultra-high viscosity where a thicker film and better gap filling are needed on large diameters.
P-68 and P-70 surface-softening primers quickly soften the pipe wall so the cement forms a stronger chemical fusion layer, measurably raising bond strength.
For chemically resistant piping systems, and for service with hypochlorite, mineral acids, hard water and saline aqueous solutions, as well as PVC chemical pipework.
A complete range from 1/2" (20mm) to 30" (800mm), so a single order covers small-bore through very large-diameter fabrication.
Curing time extends automatically in cold, humid conditions, and dedicated weather-resistant and cold-grade cements keep the joint sound in both summer heat and winter cold.
Full curing tables by temperature band, diameter, relative humidity and pressure class, plus joints-per-gallon figures, so site scheduling and consumption can be calculated in advance.
