Product Description

     Vinnyl Ester Resin Corrosion Resistance REL 470

 

Product Description

REL 470 Epoxy Vinyl Ester Resin

REL 470 resin is a novolac-based vinyl ester designed to provide exceptional
mechanical properties at higher temperatures. This resin offers a high resistance to solvents and
chemicals, good retention of strength and toughness at elevated temperatures, and excellent resistance
to acidic oxidizing environments.

APPLICATIONS AND USE
 
REL 470 resin is suitable for applications involving high temperature chlorination or caustic scrubbing and storage,industrial waste treatment facilities and solvent extraction processes used in mining.

It is also used for hydrochloric acid transport, tank, truck and railcar linings, and gasohol storage.
 
 
REL 470 resin is recommended for most commercial FRP fabrication processes including hand lay-up, spray-up, pultrusion and resin transfer molding. The higher viscosity of REL 470 resin facilitates filament winding and contact molding applications.

 

storage

It is highly recommended that all material is stored at stable temperatures below 25°C (77°F).
Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid contamination of product with water, do not store outdoors. Keep sealed to prevent moisture pick-up and monomer loss.  Mild
mixing is recommended after prolonged storage.  Rotate stock.
