PC-Seal Tape® CS 102 is a butyl rubber-based sealant specifically designed for joints in precast concrete structures and elements. It is primarily utilized as a waterstop seal for joints in precast components that are installed below ground.

AREAS OF APPLICATION

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

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.

ADVANTAGES

Provides permanently ﬂexible watertight joints.
Low to high temperature workability: -1°C to +50°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 PC-WC 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.

CHEMICAL RESISTANCE

30-Day Immersion Testing:
No visible deterioration observed when exposed to 5% Caustic Potash, 5% Hydrochloric Acid, 5% Sulfuric Acid, and 5% saturated Hydrogen Sulfide.
One-Year Immersion Testing:
No visible deterioration detected when subjected to 5% Formaldehyde, 5% Formic Acid, 5% Sulfuric Acid, 5% Hydrochloric Acid, 5% Sodium Hydroxide, 5% Hydrogen Sulfide, and 5% Potassium Hydroxide.

HYDROSTATIC RESISTANCE

PC-Seal Tape® CS 102 meets the hydrostatic performance requirements outlined in ASTM C-990, section 10.1. (Performance requirement: 10 psi for 10 minutes in a straight alignment, as specified in the in-plant quality control test for joint materials.)

INSTALLATIONS

Cleaning and Installing Sealant on Joint Surfaces Begin by thoroughly cleaning the joint surface with a stiff bristle brush, ensuring the removal of dirt, debris, flashing, and any concrete high points that may obstruct proper joint fitting. If necessary, apply a joint primer, such as PC-Prime CS Adhesive, to enhance the sealant’s adhesion. For additional information, please refer to the product brochure for PC-Wc’s PC-Prime CS Adhesive. Allow the primer to dry before applying the sealant; typically, it will feel tacky or dry to the touch within 15 to 20 minutes. When installing the sealant, exert firm pressure using the palm of your hand on the primed surface, avoiding excessive pressing or flattening. For joints, create a continuous strand by butt joining the ends of the sealant and kneading them together. Avoid stretching the sealant during installation, and refrain from overlapping at the junctions. Once the sealant is applied, refrain from stepping on it or allowing dirt or debris to come into contact with it. A minimum compression of 50% is required, with an optimal target exceeding 50%. Please note that it may take 15 to 20 minutes for the sealant to achieve full compression, depending on ambient temperature and the weight of the element being applied.

STORAGE & SHELF LIFE

24 month from date of production, if stored properly in original, unopened and undamaged sealed packaging, stored in dry conditions out of direct sunlight at temperatures between +5°C to +40°C, PC-Seal Tape® CS 102 will not experience any diminished performance.
