Product Description

 REL 510 Epoxy Vinyl Ester Resin

 

Product Description

 

REL 510 is a brominated epoxy vinyl ester resin that offers a high degree of fire retardance while providing excellent chemical resistance and toughness. Optimum fire retardance is achieved when antimony compounds are added to the resin. Laminates made with REL 510 resin have met ASTM E-84 Flame Spread "Class 2" rating (less than 75). With the use of antimony synergists,"Class 1" ratings can be achieved.


 

Our resins are a new generation of resins that can be used to improve fabrication efficiency and product quality. Their lighter color makes defects easier to see and correct while the resin is still workable. The resin's improved reactivity properties often permit an increase in lay-up thickness wet on wet. The superior stability also provides additional storage and handling flexibility for the fabricator. REL 510  resin contains only 37 weight % styrene, resulting in reduced styrene emissions.

 

 

Equipment fabricated with REL 510 resin offer excellent corrosion resistance to a wide range of acids, alkalis, bleaches and organic compounds and retains its strength, heat and chemical resistant properties when exposed to hot gases and flamable liquids.

Features & Applications

REL 510 resin is designed for ease of fabrication using hand lay-up, spray-up, flament winding, compression molding, resin transfer molding and pultrusion techniques. This resin is used extensively in FRP duct work, stacks and stack-liner applications. it is also suitable for equipment handling mixtures of air and hot gases, building panels and flooring compounds where a degree of ignition inhibiting properties are needed.

 

REL 510 resin resists mechanical and chemical damage enabling use in various caustic environments such as sodium hypochlorite, chlorine dioxide and alkaline hydrogen peroxide.
