Derakane and Derakane Momentum™ epoxy vinyl ester resins are designed and manufactured by Ashland. These resins possess outstanding corrosion-resistant properties and satisfy critical requirements in Fiber- Reinforced Plastic (FRP). Because they possess outstanding corrosion-resistant properties Derakane and Derakane Momentum resins are particularly well suited for tough industrial applications. This guide briefly describes the various Derakane and Derakane Momentum resins, and it presents detailed chemical resistance data needed to assist engineers in specifying and designing corrosionresistant...

Brief Product Description Derakane and Derakane Momentum™ 411 resins are the globally recognized standard for epoxy vinyl ester resins. They are based on bisphenol-A epoxy resin, and they provide resistance to a wide range of acids, alkalis, bleaches and solvents for use in many chemical processing applications. They offer excellent toughness and fatigue resistance. Derakane and Derakane Momentum 441-400 resins are low styrene monomer bisphenol-A epoxy vinyl ester resins with mechanical, thermal and chemical resistance properties between Derakane 411 and Derakane 470 resins. Their unique combination...

Content This listing of chemical reagents and environments shows the highest known temperature at which equipment made with Derakane and Derakane Momentum™ resins has, in general, either: • given good service in industry or • been tested in the field or in the laboratory (in accordance with ASTM C 581) with results that indicate a good life expectancy in service. It should be noted that this is not necessarily the maximum service temperature. The temperature limits in each row are representative of the whole series of resins (e.g., Derakane 411 resin applies to 411-350, 411-45, 411C-50, etc.)...

Derakane Chemical Resistance Guide English In the chemical resistance tables, a blank space simply indicates that no data was available at the time that temperature ratings were assigned. NR stands for “not recommended” at any temperature. LS stands for “limited service” (at least 3 days to 1 year at maximum 40°C/100°F). Generally in these cases, the respective resins can be used for FRP that is exposed accidentally, and where cleaning and inspection are possible after no more than 3 days. This guide is updated on a regular basis in order to take into consideration all the new experiences and...

Footnotes Information indicated in footnotes is essential in order to ensure a good service life of FRP equipment. It is strongly recommended that they are followed. 1. Double synthetic veil should be used in the CR barrier. 2. Postcure recommended to maximize service life. 3. Benzoyl Peroxide/Amine cure system with postcure recommended to increase service life. 4. Recommended provided that solvent used for dissolution is also recommended. 5. Satisfactory up to maximum stable temperature for product. 6. Check with corrosion technical service lab for specific recommendations. 7. Probably satisfactory...

Derakane Chemical Resistance Guide English Insufficient Information In cases where the environment or exposure conditions are outside the scope of this guide and if, therefore, no specific recommendations can be made, a test laminate should be exposed to the actual, or simulated, conditions proposed so that a final decision on resin suitability is made. Coatings and Linings (reinforced and non-reinforced) Coatings and linings have their own specific properties and may be limited in operating temperatures because of thermal expansion. In special cases, it is recommended to consult with the Ashland...

The information given in this guide represents the performance of full FRP structures under continuous use in contact with the stated chemical environment (unless otherwise indicated). It is sometimes difficult to predict just how aggressive certain combinations of chemicals will be toward FRP. Some mixtures are more aggressive toward FRP than the individual components, so special attention should be paid to aggressively synergistic chemicals that could not be simply predicted from the corrosion properties of the individual components. The chemical resistance also may be negatively influenced...
