Quick Overview:

Share: Messenger


A tough infusible solvent free advanced composite system developed to be used as a multipurpose high strength casting and grouting polymer. Exhibits excellent chemical resistance, corrosion resistance, and high structural integrity under stress in both compression and tension.
 
This product is designed to be used effectively in hot or cold climates, and is able to be blended with graded aggregate without appreciable loss of strength. Addition of graded aggregate is recommended when installation depth is extreme or to control excessive exotherm under hot conditions.
Suitable for use on a variety of surfaces including steel, wood, and concrete.

INSTALLATION                                                                                                      
Mixing of product should be carried out using slow speed mixers and carried out by adding component “B” to the component “A”. Once uniform in colour, mixed product should be poured directly into the area requiring treatment or applied to surfaces nominated for service. In underwater service, any water within the void will be displaced vertically.                                          
                                                                                                         
When filling large cavities, Epigen 301 may be bulk filled with equal parts by weight 16/30 mesh Silica Sand to reduce the amount of resin used. This is seen as an advantage particularly with high ambient temperature since the addition of aggregate reduces the exotherm and any resultant post cure contraction. The addition at the recommended rate will retain strength and pourability features. The kits have been designed for equal parts aggregate addition by simply topping up the mixed product container with silica sand

CURE
Variations in cure may arise due to the amount of material being applied, the thickness of material being applied, the surface temperature, and the product temperature. The cure may be increased by heating product or by leaving mixed material stand for 15 minutes before use. The cure may be decreased by cooling the product before mixing.
