J-SEAL® CJ-102 BUTYL RUBBER SEALANT

• Provides permanently flexible watertight joints.
• Low to high temperature workability: -1°C to +48°C
• Rugged service temperature: -34°C to +93°C
  Excellent chemical and mechanical adhesion to clean dry surfaces.
• Greater cohesive and adhesive strengths.
• Sealed joints will not shrink, harden or oxidize upon aging.
• Controlled flow resistance for application ease.
• No priming normally necessary. When confronted with difficult installation conditions, such as wet concrete or temperatures below 4°C, priming the concrete will improve the bonding action. Consult
  CORKJOINT for the proper primer to meet the application.
• More forgiving then a cured rubber gasket which requires perfectly formed joint areas. Butyl-rubber
  sealant has the ability to accommodate minor imperfections in the joint area.

J-SEAL® CJ-102 used predominantly as a waterstop seal for joints in precast elements that are placed below the ground.

• Manholes
• Vaults
• Septic Tanks
• Construction Joints (Non-moving Joints)
• Concrete Pipes
  Box Culverts
• Vertical and Horizontal Joints in Precast Wall

Note : The product’s design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

J-Seal® CJ-102 meets or exceeds all of the requirements of Federal Specification SS-S-210 (210-A), and ASTM C-990-91.

J-Seal® CJ-102 meets the hydrostatic performance requirement as set forth in ASTM C-990 section 10.1.

(Performance requirement: 10psi for 10 minutes in straight alignment – in plant, quality control test for joint materials.)

30-Day Immersion Testing:
No visible deterioration when tested in 5% Caustic Potash, 5% Hydrochloric Acid, 5% Sulfuric Acid, and 5%
saturated Hydrogen Sulfide.

One Year Immersion Testing:
No visible deterioration when tested in 5% Formaldehyde, 5% Formic Acid, 5% Sulfuric Acid, 5% Hydrochloric Acid, 5% Sodium Hydroxide, 5% Hydrogen Sulfide, and 5% Potassium Hydroxide.

The following procedures should be followed for optimum sealant performance.

1. Clean the joint surface with a stiff bristle brush. Remove any dirt, debris, flashing, or concrete high points, which could keep the joint from coming together.
    • If necessary, a joint primer (CJ-200-15 Adhesive) can be applied to improve sealant adhesion.
   Refer to CORKJOINT’s CJ-200-15 Adhesive product brochure for further information.
   • When using a primer, allow the primer to dry before placing sealant. The primer will normally be tacky or dry to touch within 15 – 20 minutes.
2. Install the sealant onto the primed surface with a firm force from the palm of your hand. Do not over press or flatten the sealant.
3. For joins, butt join the sealant into one continuous strand by kneading the ends together where they meet. Do not stretch the sealant during installation and do not overlap the sealant at the join areas.
4. Once the sealant is installed, do not step on or allow dirt or debris to fall on the sealant.
5. A minimum compression of 50% is required. Greater than 50% compression is optimal. It may take 15 – 20 minutes for the sealant to fully compress. This will vary according to the ambient temperature and the
   weight of the element being applied.

Waterstops where shown on the drawings shall be Superswell® 47B controlled expansion waterstop as supplied by CORKJOINT. The waterstop is to have a built-in expansion control system to minimise any pre-expansion prior to the second pour taking place and be able to withstand up to 60 metres (6.0 Bar) hydrostatic head pressure resistance. The waterstop is to be placed in accordance with the manufacturer’s installation guidelines, and the Design Engineer’s specification.
