EPIKOTE™ Resin 874L-X-90

Description

EPIKOTE Resin 874L is a Bisphenol-A based epoxy resin solution that has been modified to improve flexibility and to reduce solution viscosity. The standard product is supplied as a 90% wt solution in Xylene (EPIKOTE Resin 874L-X-90). This resin solution is ideally suited to formulate ambient temperature curing systems with significantly lower levels of Volatile Organic Compounds (VOC) when compared to conventional solvent-borne epoxy-polyamide systems. 

In ambient cure applications, EPIKOTE 874L-X-90 out-performs standard liquid epoxy resin grades with respect to flexibility of the epoxy coating; as well as, standard solid epoxy resin grades with respect to solvent emissions from the coating formulation. This epoxy resin solution can be combined with the full range of curing agents typically used for liquid epoxy resins. It is recommended for use with high performance types as Mannich bases, cycloaliphatic polyamines and low viscosity polyamides. 

Benefits

• Complies with stringent VOC requirements (<100 g/L VOC) 
• Offers the potential for cost savings 
• Very good flexibility and corrosion resistance 
• Easy application by roller, brush or spray
