Revised: 7/20
CORVE8190 is a promoted, thixotropic, corrosion resistant, epoxy vinyl ester resin for use in the manufacture of liner pipe
using cured-in-place techniques. The corrosion resistance of this resin is comparable to that of CORVE8100. Data on any
specific testing or corrosion recommendations will be supplied upon request.
FEATURES BENEFITS
Moderate Composite Exotherm Resistant to distortion during cure cycle
Fast Cure Time Shorter cycle times and fast hardness development
Good Fiberglass Wet-Out High composites physical properties
Tested Under ASTM D2990 for Flexural Modulus
Creep
Retains structural integrity under load in severe
conditions

* Gel time and reactivity will vary due to the type and concentration of Free Radical Initiator (catalyst), shop temperature, humidity, and type of fillers used. In order to meet
your individual needs, consult our technical sales representative for assistance. If using methyl ethyl ketone peroxide (MEKP) to gel and cure CoREZYN
vinyl ester resins
we recommend only these three brands: Cadox L-50a (Nouryon); Luperox DHD-9 (Arkema); and Norox MEKP-925 (United Initiators). These must be used at the
appropriate percentage and suitable temperature. Contact your Interplastic Corporation representative for assistance.
