2 2 Damival Casting Systems We Enable Energy As one of the oldest industrial companies in Switzerland, founded in 1803, we focus on products and systems for power generion, transmission and distribution, roting machines and mechanical engineering. Von Roll is the global market leader for insulion products and the only company to offer the complete range of insulion products, composites, consulting, tests and services for the electrotechnical industry. For more than 100 years, we have been making outstanding contributions to this market, developing a number of highly innovive products th have enabled both steady increases in power output and smaller and more compact machines. Customers enjoy the following benefits:» One single source for all insuling merials» Thorough expertise from power generion and transmission to its efficient utilizion» Proven compibility for system components» Testing Von Roll of both merials and systems» Consulting for applicions and technologies» Training in insulion merials and systems The requirements of the electrical and electronic industries for resins are very broad but also very specific and exacting. As a result of long and continuous work in selecting and combining approprie raw merials, Von Roll has developed a range of twocomponent potting resins Damival resins specially designed to fulfill the most demanding conditions of the electrical insulion and electronic protection markets. The Damival product range has properties excellently suited to:» Overmolding, encapsulion, impregnion» Bonding, sealing, covering, filling up empty spaces» Protecting against moisture, shocks and vibrions, harsh environments» Increasing thermal dissipion Von Roll provides an extensive range of systems designed to insule and protect electrical and electronic components.

3 Damival Casting Systems 3 Damival Casting Systems Polyurethane and Epoxy Systems for Potting and Encapsulion Von Roll s expertise in formuling and producing resins has enabled innovive Damival resins th simplify processing and save manufacturing time with low shrinkage and low sensitivity to moisture, and smooth outgassing during curing. In accordance with industrial environmental programs and directives, all grades are free of halogens and volile organic compounds (VOCs). Damival formulions comply with the Restriction on Hazardous Substances (RoHS) regulion (2002/95/EC). Several systems are UL approved (file E108253). We provide customers with global expertise and an in-depth understanding of their needs. Our Damival formulions can be adapted to mch specific requirements based on the properties desired. Our tailored solutions are developed in partnership with customers to achieve the most approprie resin system for your applicion, equipment and expected performance. The Damival range includes cold-curing systems, polyurethanes and epoxies, as well as hot-curing epoxies for mospheric and vacuum casting technologies. Damival formulions are designed to meet the most demanding specificions in numerous industries, with optimizion of mechanical and thermal characteristics as well as clients processes. Protection and insulion of capacitive and inductive components used to filter the power coming from the windmill generor Encapsulion of transformers and PCBA used in trains and subways, compliant with high safety standards Casting of motors and sensors used for oil research and extraction

4 4 Damival Casting Systems Polyurethane Damival Polyurethane systems improve overall productivity. Potting and casting can be quickly achieved thanks to fast hardening room temperure. This is a noticeable advantage over traditional merials such as silicones and epoxies. A variety of resin formulions can be blended with several hardeners to produce many different grades, each having selected properties th mch processing requirements and adeque characteristics on finished products. Our polyurethane resins are used for potting, encapsulion, impregnion and insulion of electric devices. These tailored solutions optimize mechanical and thermal characteristics as well as clients processes. The main advantages of polyurethane Damival are:» Adaptable viscosity and gel time» Customized processability» Variable flexibility of the cured resin» Low shrinkage» Low exothermic reactions» Good adhesion on most surfaces» Excellent resistance to vibrions and rising temperure» Suitable for a wide range of opering temperures, from 60 C up to 155 C Von Roll has available a twofold range of Damival polyurethane resins: 135xx and 136xx. The 136xx resin systems are real elastomer merials th combine outstanding adhesion, flexibility even very low temperure as well as very low moisture absorption. These are cost-effective substitutes for silicone elastomers. The TMA method shows a high stability of the coefficient of thermal expansion from 60 C up to 120 C for Damival Probe Position (mm) Temperure ( C) Damival polyurethane resin is designed to efficiently integre many fields of applicion in the electronic, electrical, power-supply device, medical, automotive, marine, railway, aircraft and military industries.
