Epoxies - Sikadur®-30

High-modulus, high-strength, structural epoxy paste adhesive for use with Sika® CarboDur® reinforcement.

Sikadur®-30 is a 2-component, 100% solids, moisture-tolerant, high-modulus, high-strength, structural epoxy paste adhesive. It conforms to the current ASTM C-881 Type I, IV Grade 3, Class C and AASHTO M-235 specifications.

• Long pot life.
• Long open time.
• Tolerant of moisture before, during and after cure.
• High strength, high modulus, structural paste adhesive.
• Excellent adhesion to concrete, masonry, metals, wood and most structural materials.
• Fully compatible and excellent adhesion to Sika® CarboDur® CFRP composite laminate.
• Paste consistency ideal for vertical and overhead applications of Sika® CarboDur®.
• High abrasion and shock resistance.
• Convenient easy mix ratio A:B=3:1 by volume.
• Solvent-free.
• Color-coded components to ensure proper mixing control.

Usage

• Adhesive for bonding external reinforcement to concrete, masonry, steel, wood, stone, etc.
• Structural bonding of composite laminates (Sika® CarboDur® CFRP) to concrete.
• Structural bonding of steel plates to concrete.
• Suitable for use in vertical and overhead configurations.
• As a binder for epoxy mortar repairs.

Application

Application Information

Component ‘A’: Component ‘B’ = 3:1 by volume.

Approximately 70 minutes @ 73°F (23°C) (1 qt.)

Consumption

Type S 512 CarboDur®: approx. 50 LF/gal.; Type S 812 CarboDur: approx. 32 LF/gal.;
Type S 1012 CarboDur®: approx. 22 LF/gal.

Application Steps

The concrete surface should be prepared to a minimum concrete surface profile (CSP) 3 defined by the ICRI surface-profile chips. Localized out-of-plane variations, including form lines, should not exceed 1/32 in. (1 mm). Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials, and other bond inhibiting materials from the surface. Existing uneven surfaces must be filled with an appropriate repair mortar (e.g., Sikadur® 30 with the addition of 1 part oven-dried sand). The adhesive strength of the concrete must be verified after surface preparation by random pull-off testing (as defined by ACI 503R, ASTM C1583) at the discretion of the engineer. Minimum tensile strength, 200 psi (1.4 MPa)
with concrete substrate failure.

Concrete - Blast clean, shot blast or use other approved mechanical means to provide an open roughened texture.
Steel - Should be cleaned and prepared thoroughly by blast cleaning to a white metal finish.
CarboDur® - Wipe clean with appropriate cleaner (e.g. MEK)

Pre-mix each component. Proportion 1 part Component ‘B’ to 3 parts Component ‘A’ by volume into a clean pail or appropriately sized mixing container. Mix thoroughly for 3 minutes with Sika paddle on low speed (400-600 rpm) drill until uniform in color. Mix only that quantity which can be used within its pot life.

To prepare an epoxy mortar: slowly add up to 1 part by loose volume of an oven-dried aggregate to 1 part of the mixed Sikadur® 30 and mix until uniform in consistency.
