PC® 136 adhesive is a reactive cementitious product that is mixed with water to form an inorganic, noncombustible adhesive or coating for fabricating, or bore coating. PC® 136 adhesive is normally used at ambient and above temperatures to 900°F (482°C) where stresscrack corrosion is a concern with stainless steel.

HOLD Catalyst is a solution of an organometallic compound in mineral spirits. It is applied by a suitable small sprayer to an applied PC® 88 adhesive ( FI-125) layer. It provides quick set and will reduce or eliminate the time needed for temporary support in unsupported or overhead FOAMGLAS® insulation applications. It may be used to fabricate FOAMGLAS® insulation shapes using PC® 88 adhesive as the bonding agent.

Hydrocal® B-11 is a reactive gypsum product that is mixed with water to form an inorganic, noncombustible adhesive or coating for fabricating, bore coating, or forming HT reinforced FOAMGLAS® insulation shapes. Hydrocal® B-11 is normally used at operating temperatures above 200°F (93°C), or in other special situations.

PC® Fabric 79 is an open mesh, synthetic fabric for reinforcing PITTCOTE® 404 (FI 138) or PITTCOTE® 300 (FI-120) coating over FOAMGLAS® insulation. The large mesh openings allow the coating to easily penetrate and bond to the insulation and fabric. The thickness of the fabric assures that the proper thickness of the coating is applied and gives the required strength. The high elongation accommodates large and mechanical movements without rupture and allows maximum movement of the coating.

PC® RTV 450 Silicone Adhesive is a one-part, acetoxy cure, silicone adhesive/sealant formulated for use at high temperatures. It is particularly suited for use in conjunction with FOAMGLAS® insulation systems that require adhering or sealing the insulation to itself or to hot surfaces. It cures to an elastomeric solid at room temperature.

PITTCOTE® 300 finish is a vapor and weather barrier asphalt coating especially formulated for use with FOAMGLAS® insulation in the low to moderate temperature range. PITTCOTE® 300 finish is available in trowel and spray grades. Spray grade is a special order. Application is by spray, trowel or glove.

PITTCOTE® 404 coating is a highly flexible, acrylic latex coating used with FOAMGLAS® insulation where a superior weather barrier coating is required PITTCOTE® 404 coating is available in colors and may be applied by glove, trowel, brush, or spray.

PITTSEAL® 444N sealant is a specially formulated butyl sealant used for sealing joints in FOAMGLAS® insulation systems, and to seal protrusions and metal jacket laps. This single component sealant is certified to meet stainless steel service requirements of MIL-I-24244 and NRC Regulatory Guide 1.36.

PITTSEAL® 727 sealant is a specially formulated styrene-butadiene rubber sealant used for sealing joints in FOAMGLAS® insulation systems, and to seal protrusions and metal jacket laps. It is the prefered sealant for chilled water applications. PITTSEAL® 727 sealant is compatible with a wide variety of coatings.

PITTWRAP® CW30 jacketing is a 30 mil thick self-sealing, non-metallic sheet for protecting above ground FOAMGLAS® insulation systems on chilled water and hot service pipelines. Manual pressure seals the jacketing without the use of a torch or heater. Metal jacketing must be used over the PITTWRAP® CW30 jacketing for UV protection. PITTWRAP® CW30 jacketing consists of a polymer modified bituminous compound reinforced with a 4 mil. high density cross laminate polyethylene top film and release paper backing.

PITTWRAP® CW PLUS jacketing is a 50 mil thick self-sealing, modified bituminous membrane for protecting underground FOAMGLAS® insulation systems on chilled water and hot service pipelines. Manual pressure seals the jacketing without the use of a torch or heater. PITTWRAP® CW PLUS jacketing may also be factory-applied on the insulation. PITTWRAP® CW PLUS jacketing consists of a polymer modified bituminous compound reinforced with a glass fabric and a 1 mil aluminum top film and release paper backing.

PITTWRAP® IW50 jacketing is a 50 mil thick self-sealing, non-metallic sheet for protecting above ground FOAMGLAS® insulation systems on chilled water and hot service pipelines. Manual pressure seals the jacketing without the use of a torch or heater. Metal jacketing must be used over the PITTWRAP® IW50 jacketing for UV protection PITTWRAP® IW50 jacketing consists of a polymer modified bituminous compound reinforced with a glass fabric, a 1 mil polyester film and release paper backing.

PITTWRAP® jacketing is a heat sealable, multiply laminate for protecting underground FOAMGLAS® insulation systems for outer surface temperatures below 190°F. PITTWRAP® jacketing consists of three layers of a polymer modified bituminous compound separated by glass fabric reinforcement and aluminum foil. An outer layer of polyester film is laminated to the bituminous compound. An outer layer of polyester film is laminated to the bituminous compound. A release paper prevents sticking in the roll before use.

PITTWRAP® SS jacketing is a 70 mil thick self-sealing, modified bituminous membrane for protecting underground FOAMGLAS® insulation systems with outer surface temperatures below 170°F (76.7°C). Manual pressure seals the jacketing without the use of a torch or heater. PITTWRAP® SS jacketing may also be factory-applied on the insulation. PITTWRAP® SS jacketing consists of a polymer modified bituminous compound reinforced with a woven glass fabric and a 1 mil aluminum top film and release paper backing.

PITTWRAP® SS Primer is specially formulated to promote adhesion of PITTWRAP® self-sealing jacketing when the laps are slightly dusty or the application is below 50°F (10°C).

Terostat PC is a vapor/ weather barrier coating and sealant/adhesive especially formulated for use with FOAMGLAS® insulation in the low to moderate temperature range. Terostat PC is available in trowel/extrusion grade. Application is by trowel, glove or extrusion.
