polyester resin / composite / water-resistant / chemical-resistant

The Reichhold DION® 250-410 is a medium reactive isophtalic neopenthylglycol and pre-accelerated polyester resin. It is specially engineered to deliver optimum hydrolytic stability as well as optimum repelling of water, salts oil and diluted acids. This in turn makes it suitable for rehabilitation of sewage pipes. This can exhibit minimal water absorption as well as reliable protection from acidic environments like sewage, diluted organics and mineral acids. This can be utilized with ATH and CaCO3 elements as fillers. This strictly complies with Type 1140 resin in accordance to DIN 16946/2 as well as Group 3 classification in accordance with DIN 18820/1.
