- Additional Benefits
- StrongBondTM 200 Adhesive Putty System is formulated to improve the intimate bond between the epoxy adhesive and cured carbon fabric laminate. This formulation technique results in increased physical properties due to better surface wetting and increased bond strength. Of equal, if not greater significance is the retention of physical properties after exposure to heat, cycle fatigue, water, expected adverse environmental reagents such as salt spray, acid rain, etc.
- The formulation of StrongBondTM 200 Adhesive Putty System results in minimal degradation of the cured adhesive’s physical properties as compared to epoxy systems not containing the proprietary formulation constituents of StrongBondTM 200 Adhesive Putty System. This technology offers the fabricator not only a superior adhesive today, but more importantly, increased product life and long-term durability.

- Applications
- Use StrongBondTM 200 Adhesive Putty System to bond carbon fabric to carbon fabric materials or other materials such as concrete, metal, wood, and many plastics. It is recommended StrongBondTM 200 Adhesive Putty System be used on large composite parts such as utility scale wind rotor blades, truck panels, railroad or ocean freight containers, etc.
- StrongBondTM 200 Adhesive Putty System is highly recommended for bonding pre-cured epoxy laminate to itself and dissimilar materials (concrete, steel, aluminum) in the areas of seismic retrofit and structural upgrades

Technical Details & Test Data
- Recommended Curing of StrongBond™ 200 Adhesive Putty System
- Gel at ambient + 8 hours at 50 ℃
- Gel at ambient + 6 hours at 70 ℃
- Gel at ambient + 7 days at ambient
- Surface Preparation
- All surfaces should be mechanically abraded or in the case of carbon fabric laminate, the use of peel ply on the bonding surfaces is acceptable. All dust, grease, and standing water must be removed prior to the application of StrongBondTM 200 Adhesive Putty System.
- Steel: Remove all oil and grease from surface with an SSPC SP1 solvent wipe prior to blasting. Abrasive blast to an SSPC SP10 near white metal blast with profile more than 3 mils (more than 75 microns).
- Steel (Atmospheric Corrosion): Remove all oil and grease from surface with an SSPC SP1 solvent wipe. StrongBondTM Page 3 of 4 200 Adhesive Putty System Minimum surface preparation of SSPCSP2 hand tool cleaning must be performed. For enhanced performance, an SSPCSP6 commercial blast cleaning with surface profile of 2+ mils should be used.
- Concrete: Refer to SSPCSP13/ NACE 6, Section 4.3.1 or ICRI No. 310.2, CSP 1-3 for concrete preparation guidelines. Surface should be thoroughly cleaned and dry. Concrete and mortar must be cured at least 28 days at 75 °F. Surface must be free of laitance, concrete dust, dirt, form release, curing aids and other foreign material.
- Concrete (Atmospheric Corrosion): Refer to SSPCSP13/ NACE 6, Section 4.3.1 or ICRI No. 310.2, CSP 1-3 for concrete preparation guidelines.
- Previously Coated Surfaces: Consult with ALD Technical Solutions LLC to ensure previous coating is compatible. If compatible and previous coating is in good condition, remove all loose coating and foreign materials. Brush blast or grind all glossy areas to a uniform dull finish. Remove dust, oil and debris with SSPC SP1 solvent wipe prior to coating.
