PRODUCT DESCRIPTION


NCL DH-50 ACRYLIC SEAL is an acrylic-based, low viscosity waterproofing resin and curtain grouting material designed to stop water leakages especially underground infrastructure in permanent water contact such as tunnel, subway, basement etc. Generally, the acrylic resin is injected behind leaking concrete structure into the soil layer. The reaction time of the material is controllable with the addition of Catalyst to cope with different site condition. Once cured, NCL DH-50 ACRYLIC SEAL forms a highly elastic water-impermeable layer which prevent concrete structure from damages caused by external groundwater infiltration.
 
 
COMPOSITION
 

NCL DH-50 Acrylate Seal is a multi-component acrylic gel system which consists of Part (A) Resin, Part (A) Catalyst, Part (B) Resin and Part (B) Hardener. The sub-components are pre-mixed with the main components before application (refer to NCL DH-50 Mixing Method). All components are then intermixed during application to form highly flexible acrylic gel.

STORAGE & HANDLING
It is recommended to keep container tightly closed in a cool (20 - 25°C), dry and well-ventilated place. Partly used drums/pails should be properly sealed to prevent ingress of moisture. To increase the material life expectancy, partially used drum/pail can be filled with nitrogen gas and sealed tightly to prevent contamination. When the material is stored properly, the shelf life is approximately twelve (12) months from the production date.
 


WASTE DISPOSAL

Waste disposal should be in accordance with all applicable local and national regulations. Kindly check with the local authorities on proper disposal method. Empty drums/pails should be punctured to clear the content. Care must be taken to prevent environmental contamination from the use of this material.
