ORCHEM™ – 907 is a medium viscosity, high reactivity, non pre accelerated, non thixotropic, high heat deflection thickenable unsaturated polyester resin based on isophthalic acid. It is intended for SMC & DMC production in low shrink and controlled shrink applications ,designed for compression and injection molding. It can easily be pigmented, exhibits excellent catalyzed stability and shows uniform thickening response with extended wet out time.It is compatible with all types of LPA. Moulded parts exhibit excellent surface finish, high toughness , crack resistance , higher corrosion resistance, hydrolytic stability, improved mechanical strength and thermal and electrical insulating properties
