HETRON 197 resin is a non-thixotropic, unpromoted, halogenated, flame retardant
(1) clear
polyester. HETRON 197 resin may be used for closed molding applications. HETRON 197 resin can
be formulated into other HETRON resins of the 197 series (except HETRON 197AT resin) with the
addition of styrene, thixotrope agents or promoters.
– Excellent corrosion resistance to acidic and other oxidizing environments
– High heat resistance – gases and vapor to 177 C (350 F)
– Excellent strength retention at elevated temperatures
– Good fire retardancy – Has met ASTM E-84 Class II rating with 5% antimony trioxide
APPLICATIONS AND
USE
Corrosion resistant fiberglass reinforced plastic equipment including press molded and pultruded
pipe, flanges, fittings, pumps, pump housings, mist eliminator blades and other equipment
handling corrosive gases, vapors or liquids.

(1) HETRON polyester resin will burn if provided with a sufficient amount of heat and oxygen. The
degree of flame retardancy of the cured polyester resin is characgterized by the ASTM E-84 tunnel
test. This test is performed under strictly controlled conditions where a flame spread rating is
assigned according to comparisons with test set-point materials. The behavior of the cured
composite under these controlled conditions can vary from an actual fire situation.
(2) Properties are typical values based on material tested in our laboratories. Typical values should
not be construed as a guaranteed analysis of any specific lot or as specification items.

CERTIFICATES AND
APPROVALS
The manufacturing, quality control and distribution of products, by INEOS Composites, comply with
one or more of the following programs or standards: ISO 9001, ISO 14001 and OHSAS 18001.
STANDARD PACKAGE Non-Returnable Drum with Net Weight of 240 Kgs (529 Lbs)
DOT Label Requirement: Flammable Liquid
COMMERCIAL
WARRANTY
Three months from date of shipment, when stored in accordance with the conditions stated below.
STORAGE Drums - Store at temperatures below 25 C (77 F). Storage life decreases with increasing storage
temperature. Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid
contamination of product with water, do not store outdoors. Keep containers sealed to prevent
moisture pick-up and monomer loss. Mild mixing is recommended after prolonged storage. Rotate
stock.
Bulk - See INEOS Composites's Bulk Storage and Handling Manual for Polyesters and Vinyl Esters. A
copy of this may be obtained from INEOS Composites at +1-614-790-3333 or 800-523-6963.
All other conditions being equal, higher storage temperatures will reduce product stability and
lower storage temperatures will extend product stability.
