Product catalog summary
Product Overview: HEMPASIL NEXUS X-TEND 27500 is a high solids, silicone-based humidity curing tiecoat designed for use with HEMPAGUARD®/HEMPASIL topcoats. It is primarily used for touch-up and repair of damaged silicone top coats, ensuring adhesion between the anticorrosive system and the topcoat. It can also be used as a low-temperature tiecoat in combination with HEMPEL'S NEXUS II 27400 for full coat applications.
Specifications: The product has a semi-gloss finish with a volume solids percentage of 65%. The theoretical spreading rate is 5.4 m²/l at 120 microns. The VOC content is 252 g/l, and the product is fully cured in 2 days at 20°C. The flash point is 28°C, and the specific gravity is 1.2 kg/litre. The shelf life is 18 months from production.
Application Details: Application methods include airless spray and brush/roller for touch-ups. No thinning is recommended, and the nozzle orifice should be 0.019 - 0.021 inches with a pressure of 150 bar. The indicated dry film thickness is 120 microns, and the wet film thickness is 175 microns. Overcoat intervals are specified according to the system requirements.
Surface Preparation and Conditions: Surfaces must be dry and clean, with temperatures above the dew point to prevent condensation. Application and curing should occur at temperatures above 5°C for maintenance and above 0°C for low-temperature tiecoat applications. Adequate ventilation is necessary in confined spaces, with relative humidity between 30% and 85%.
Preceding and Subsequent Coats: Recommended preceding systems include HEMPADUR 15570 or HEMPEL’S NEXUS II 27400. Subsequent coats should be HEMPASIL or Hempaguard® systems.
Remarks: Thorough protection and cleaning procedures are essential before and after application. It is advised to apply the HEMPAGUARD®/HEMPASIL SYSTEM after completing other exterior painting to avoid contamination. Equipment should be cleaned thoroughly with THINNER 08080, and solvents should not be reused.
Safety and Handling: Handle with care, observing all safety labels and regulations. Consult HEMPEL Safety Data Sheets for detailed safety information.
Storage and Disposal: Store under dry conditions, protecting against humidity. Dispose of cleaning solvents after use.
