Dow Expands Portfolio of Innovative MDI-based Products

MIDLAND, MICH. – June 24, 2015 – Dow Polyurethanes, a business of The Dow Chemical Company

(NYSE: DOW), today announced the expansion of their methylene diphenyl diisocyante (MDI) product

family. As highly, versatile chemistry, the expanded MDI offering provides customers the option of

these products as components or in fully formulated systems for opportunities in a wide range of

markets. The new products include VORAMERTM MN 2314 Prepolymer, PAPITM 23 High Airflow

Isocyanate, VORASTARTM 7000 Spray Elastomer System, and ISONATETM 128 modified MDI.

“These new MDI products are core to our commitment to addressing societal challenges in markets with

the power of material science and innovation,” said Chris Chrisafides, commercial vice president, Dow

Polyurethanes. “We have strengthened our offering and that shows commitment to our customers and

the markets they serve. Our comprehensive portfolio of performance products and tailor-made

solutions – from polyether polyols, propylene oxide and propylene glycol to quality isocyanates,

including MDI – combined with industry leading experts provide the support and quality materials that

customers need to grow.”

VORAMER MN 2314 Prepolymer is a highly-processable, cost-effective polyurethane solution

for formulating concrete adhesives and sealants. Providing desirable processing and reactivity

for use in moisture-cure systems because of its low viscosity, VORAMER MN Prepolymer

eliminates extra work and time associated with stripping old coatings and provides distinct

advantages when compared to incumbent products, including performance in standing water,

resistance to dirt pick up and strong adhesion and paintability.

PAPI 23 High Airflow Isocyanate is a superior performing MDI for use in high-end viscoelastic

foams for the bedding industry, helping customers provide consumers with quality bedding to

achieve a cool sleep effect. PAPITM 23 High Airflow Isocyanate has high o,p' content providing

excellent processing, and enhanced foam physical properties. Inherent to the polymer’s

molecular design, PAPI 23 enables good airflow in and out of the foam cells to help consumers

achieve a better night’s rest.

VORASTAR 7000 polyurethane spray elastomer system is a novel product designed for use in

surface protection of porous concrete containment structures and steel exposed to advanced

chemical attack. A high performance, two-component polyurea hybrid coating material,

infrastructure owners using VORASTAR 7000 system can extend the life of steel tanks, pipeline

and chemical holding tanks thus enabling lower total cost of ownership. The low viscosity of

VORASTAR 7000 facilitates processing and allows applicators to achieve a smooth high gloss

finish and fast return to service, as well as a good balance of strength and elongation, abrasion,

and wear and tear resistance due to its elastomeric properties. The system performs very well in

low temperature environments and maintains its flexibility even in temperatures down to

negative 50 degrees Celsius.

 ISONATE 128 is a modified MDI offering superior handling and storage stability. ISONATE 128

MDI was designed to balance needs for ease of processing without sacrificing excellent

mechanical properties in end use applications, like elastomers. Also, the new ISONATE 128

enables less energy consumption required for storage, providing customers the flexibility to

manufacture products through a longer period of the year without additional insulation during

storage.
