Olin D.E.N. Novolac Resins
High performance epoxy resins for high temperature, great adhesion & chemical resistance.


Olin Corporation is a leading vertically integrated global manufacturer and distributor of chemical products and a leading US manufacturer of ammunition. The chemical products produced include chlorine and caustic soda, vinyls, epoxies, chlorinated organics, bleach and hydrochloric acid. Winchester's principal manufacturing facilities produce and distribute sporting ammunition, law enforcement ammunition, reloading components, small caliber military ammunition and components, and industrial cartridges.
Olin began in 1892 as a small blasting powder supplier in East Alton, Illinois, and expanded with the acquisition of Mathieson Chemical Corporation. Olin now encompasses several complementary business units, including Olin Chlor Alkali Products & Vinyls and Olin Epoxy. In 1931, Olin brought Winchester, the leading manufacturer of ammunition in the United States, into the fold. Collectively, these business segments operate in more than 20 countries with customers in nearly 100 countries across the globe.


Olin's D.E.N. epoxy novolac resins provide reliable protection in tough applications like containment tanks, concrete, pipes and marine environments. These resins are ideal for coatings, encapsulants, composites and adhesives and provide:
- Superior mechanical performance for heat and chemical resistance in comparison to Bisphenol A resin and unsaturated polyester systems
- Minimal shrinkage in encapsulant, composite, adhesive and binder applications
- Improved adhesion at elevated temperatures in adhesives. Excellent adhesion & cohesion to fibers and fillers in composite formulations
Advancion's high-purity ULTRA PC™-grade amino alcohols are designed to deliver robust multifunctional performance and broad formulating latitude across a wide range of beauty and personal care applications. With efficient neutralization and buffering properties, as well as superior compatibility with a broad spectrum of other well-known formulating ingredients, ULTRA PC-grade amino alcohols aid in the formulation of beauty and personal care products with improved performance, enhanced stability, and exceptional aesthetic properties.

Product | Viscosity @25 °C (mPa•s) | Description |
D.E.N.™ 424 | 5,700-6,800 | Low viscosity epoxy novolac resin with a similar equivalent weight to standard Bisphenol A and Bisphenol F yet having increased chemical resistance and high temperature performance. Uses would include composites, coatings, adhesives and encapsulants where a lower viscosity is needed. |
D.E.N.™ 426 | 18,000-23,000 | Epoxy novolac resin with a viscosity similar to standard bisphenol A epoxy resins but increased chemical resistance and high temperature performance. Application would include high build coatings, adhesives and encapsulants. |
D.E.N.™ 428 | 35,000-45,000 | Developed to fill the gap between the two functional standard bisphenol F based liquid epoxy resins and high viscosity novolac resins with increased functionality, producing more cross-linkage and improving high temperature performance and chemical resistance. |
D.E.N.™ 440 | 50,000-90,000a | Highly functional epoxy novolac resin creating a high crosslink density. The highest performance is achieved in regards to mechanical, temperature and chemical resistance properties. |
