DURA-FILL® 1190 NR

Joint Sealant for Moderate Climates

General Information

Description: Dura-Fill 1190 NR is a hot pour crack and joint sealing compound for portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, Dura-Fill pro-longs pavement service life by sealing cracks and surface joints from water penetration. Dura-Fill 1190 NR is a single component, specially formulated mix of asphaltic resins, synthetic polymeric rubbers, plasticiz-ers, stabilizers and organic reinforcing fillers. When properly melted and applied, it forms a resilient and adhesive compound for both cement and asphaltic pavements. Dura-Fill 1190 NR forms a long lasting seal which resists tracking in warm temperatures and cracking in cold. 

2-2021 Recommended Uses: Dura-Fill 1190 NR is recommended for sealing joints and cracks in portland cement and asphaltic pavements. It is designed to seal expansion and contraction joints, longitudinal and trans-verse cracks, joints between concrete and asphaltic shoulders and random cracks. 

Surface Preparation: Proper surface preparation facilitates adhesion and consequently the maximum service life of the sealant. In order for proper adhesion to occur, the crack/joint must be free of moisture, dust, loose aggregate and other contaminates. The substrate and air temperatures must be 40°F or above. Sawing, routing and/or sandblasting are the preferred methods of preparation. Use oil-free compressed air and heat to clean and dry the crack/joint immediately prior to sealing. Cracks/joints should be sized so that the maximum extension and compression do not exceed 50% of the width. Best results are obtained when the cracks/joints are opened at least ½ inch wide. 

Melting and Application: Melt Dura-Fill 1190 NR using a conventional oil jacketed kettle equipped with agitator and temperature control devices for both the material and heat transfer oil. Carefully insert small quantities of Dura-Fill and the plastic bag into the melting equipment while the agitator is turned off. Load material slowly to avoid splash back. After the initial load has reached the recommended pouring temperature, fresh material may be added to the melter as sealant is used. Melt only the material that will be used during that day. Purge material remaining in the melting kettle lines at the end of each sealing operation. The material may be safely reheated and can be applied using a pressure fed wand system or a pour pot. 

Note: The temperature of the heat transfer oil should not exceed 525°F. Do not heat Dura-Fill above the maximum heating temperature and do not maintain it at that temperature for prolonged periods of time. This could cause the material to gel in the equipment or fail in the joints. A significant viscosity increase accompanied by stringiness signals the approach of gelation. If this occurs, immediately remove the materi-al from the melter and dispose of it.
