PYROK ACOUSTEMENT™ 40 PRODUCT DATA

1. DESCRIPTION
Pyrok Acoustement 40 is a nominal 41 PCF (air-dried density) portland cement/exfoliated vermiculite spray-applied formulation 100% free from asbestos and mineral fibers, polystyrene and cellulose. Pyrok Acoustement 40 is highly abuse resistant (impact, abrasion, moisture, hostile industrial environments), has excellent adhesion to a variety of substrates, allows substrates to breath and be cleaned by a variety of methods.

2. USES
Pyrok Acoustement 40 can be used as a decorative surfacing material, an acoustically attenuating surfacing material or as a combination of these qualities even in conjunction as a fire- proofing material.

This material is recommended for exterior exposures where resistance to environmental pollution, rain, corrosion and spalling is required. It may be used in interior exposures where superior abuse resistance is required.

Typically Pyrok Acoustement 40 is specified for transportation facilities, correctional projects, lobbies, atriums, tunnels, natatoriums, gymnasiums, manufacturing facilities, contact wall areas, and any other area requiring high abuse resistance and sound absorption qualities.

It can also be used on interior surfaces of walkways, hallways and rooms where a purely decorative finish is desired.

Pyrok Acoustement 40 may also be used on ceilings as a combination acoustical finish and fireproofing material.

Custom integral coloration is available within the limits of iron oxide pigmentation.
