Technical Details & Test Data
- Hardener Application Recommendations
- All hardeners reach sufficient strength for return to service or demolding after an overnight ambient cure. The fastest StrongBond™ 420B Saturant Hardener-Part B, is useful for winter applications or for mixing in smaller batches.
- StrongBond™ 410B Saturant Hardener-Part B is the standard 30-minute system hardener used for 4:1 volume mixing applications.
- StrongBond™ 430B Saturant Hardener-Part B is used in high temperature applications (up to 240˚F) and is 4:1 by volume which is also useful in hot weather or for large areas.
- StrongBond™ 400B Saturant Hardener-Part B is the standard 1-hour, general purpose hardener and may be certified to NSF Standard 61 for potable water.
- Cure Schedule for StrongBond™ 400 Saturant Resin System
- Allow the composite to cure at the recommended temperature as listed in the physical properties chart (above).
- In the case of all listed hardeners, allow at least 6 – 8 hours at ambient (>65°F) temperature or 2-3 hours at 130°F before attempting to return the composite to service.
- In colder weather (less than 65°F) allow additional time for the composite to cure. After the recommended elevated temperature cure, all systems may be exposed to the listed service temperatures.
- In all cases, an elevated temperature cure of 2-4 hours at 120°F-140°F assures the highest quality product.
- Surface Preparation
- 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. 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.
