TECHNICAL DATA
1/2
CRC RIGID SEAL
For machined flanges
Ref. : 10769
1. GENERAL DESCRIPTION
Anaerobic adhesive based on methacrylate esters, developed to replace preformed gaskets
on machined flanges.
The adhesive has a relative fast initial setting to allow the application of moderate pressure.
2. FEATURES
• Moderate and controlled shear strength.
• Thixotropy and high viscosity provide the adhesive with a good filling capacity.
• Suitable for machined metal flanges.
• Seals immediately under low pressure (< 10 kg/cm²).
• Great resistance to: temperature, corrosion, vibrations, water, gas, oils, hydrocarbons
and most chemicals.
• Difficult to dismount with normal tools, even after some years.
• Does not run or drip off.
• Does not migrate after assembly.
• Not suitable for plastic connections.
• Soluble in oil.
3. APPLICATIONS
Adhesive specially recommended for:
• Sealing of metallic, machined flanges, where all the composing parts have a limited
difference in thermal expansion coefficient.
• Replaces and eliminates the use of pre-cut gaskets.
4. DIRECTIONS
Best results are obtained on clean, dry and grease free surfaces. For best results, use CRC
Industrial degreaser. In general, roughened surfaces give higher bond strengths than
polished or ground surfaces.
Apply a bead of CRC Rigid Seal along the complete flange and around the bolt-holes and
studs.
Assemble and apply the needed pre-torque when applicable. The assembly can be put
immediately under low pressure (< 10 kg/cm²). The functional curing time is obtained after 1
to 3 hours and full resistance can be expected 12 to 24 hours from application. When
assembled, any possible excess adhesive can be removed with a dry cloth or tissue.
Clean cured product by tramping the part for 10 min. into CRC Super Gasket Remover.
Flush with water and remove remnants with a nylon brush.
