Available standard sizes

PPG offers standard sizes that fit most applications and the

ability to custom design a seal cap to meet your specific

need. For a complete list of sizes, PRC Seal Cap drawings,

or to place an order, contact PPG's worldwide network of

aerospace application support centers (ASCs). For the ASC

Typical applications

Typical applications for PRC Seal Caps may include the

sealing of rivet heads or fasteners.

Storage life

The storage life of pre-mixed and frozen PRC Seal Caps is 30

days at -40°F (40°C) for polysulfide caps and -80°F (-62°C) for

polythioether caps.

Application steps

PRC Seal Caps are provided in easy-to-handle trays. If filled

with pre-mixed and frozen sealant, remove seal caps from the

freezer. Place trays on bench at 70°F to 80°F (21°C to 27°C)

and thaw for 15 to 30 minutes.

Important: Leave tray assembly together during thaw to

prevent condensation being deposited on the PRC Seal

Caps. Once thaw is complete, gently remove the tray from the

aluminized lid. To remove PRC Seal Cap, lightly pinch the cap

and slide off the foil lid, using a sight “flicking” motion.

What are PRC

Seal Caps?

PRC

SEAL CAPS are pre-formed and molded caps made

from any PRC

or PRO-SEAL™ brand sealant including

standard polysulfide or PERMAPOL

polythioether materials.

They are formed and then cured to a flexible rubber shell, and

then filled with additional sealant to be used for dome-sealing

of fasteners.

Why PRC Seal Caps?

Faster

• Decreased application time and elimination of tooling.

• Use of filled and frozen caps eliminates mixing of

cartridges and cap filling.

• Designed to fit specifically to each fastener.

Cleaner

• No wet sealant application or tooling

• Eliminates foreign object damage (FOD).

• Eliminates empty cartridges when pre-mixed and frozen

(PMF) caps are used.

• Requires less solvent for clean up.

Easier

• Custom sizes available.

• Use only what is needed.

PRC Seal Caps technology

PRC Seal Caps are formed using aerospace sealant already

qualified to the appropriate specification. PRC Seal Caps can

be made from either polysulfide or Permapol

polythioether

B-grade materials. PRC Seal Caps can provide significant

improvements in quality, efficiency and ergonomics versus

traditional sealing methods. PRC Seal Caps can be ordered

already filled with pre-mixed and frozen sealant or as empty

caps to be filled at the application station.

Important: Do not lift cap straight up, as this will leave the

wet sealant on the aluminized lid. Apply PRC Seal Cap to

properly cleaned and prepared fastener. Use slight downward

pressure while turning cap one half rotation. Once cap is fully

seated, you should inspect to ensure that a complete squeeze

out of wet sealant is observed around the bottom of the caps

perimeter. This indicates a proper seal.
