1 Voltatex 3110 PUR-Casting Resin Components Casting Resin: Voltatex 3110 Hardener: Voltatex 5131 or Voltatex 5132 Chemical Base Casting Resin: Hardener: hydroxy-functional polyester aromatic polyisocyanate Product description Pigmented, filled and cold-curing two-component polyurethane casting resin with low temperature development while curing. Voltatex 3110 is compliant with the EU-directives /11/EU (polybrominated diphenyl ethers) /121/EU (REACh-directive) /65/EU (RoHS- directive) Special properties flame retardant free of halogens or antimony oxides non-abrasive, filled with chalk elastic low water absorption resistant to transformer oil and organic solvents and gases such as benzines and carbon hydrides good adhesion on most metals and plastics except on anodized, smooth surfaces especially on light metals Temperature Class (E B) UL-approval Flame retardant acc. to UL 94 V-2 UL-File-Nr.: E72640 (M) Underwriters Laboratories Inc, USA Application area Embedding and potting of transformers and electronics, especially of heat-sensitive electronic parts such as transistors, photo cells, etc. Voltatex 3110 contains non-abrasive fillers and is therefore especially suitable for sensitive mixing and dispensing equipment Voltatex 3110 Issue 03/ page 1 of 8

2 Mixing ratio Voltatex 3110 : Voltatex 5131 resp. 5132: 100 : 30 parts by weight Processing Due to the contents of fillers which will settle to the ground during a longer storage period Voltatex 3110 needs to be stirred up homogenously (without including foam) prior to use. In any case the resin shall rest for about 2 hours after stirring to allow degasing The time needed for degasing the resin may be shortened by storing the resin at approx. 60 C or at a vacuum of approx. 20 mbar. Provided the mixture is consumed very soon, the hardener Voltatex 5131 or Voltatex 5132 may be added to the warm resin. Otherwise the resin has to cool down to room temperature again in order to avoid a significant shortening of the mixture s pot life. Casting resin, hardener and mixtures made must be protected against humidity! The temperature in the working area must be above 18 C! The same way it is essential to dry the parts the casting resin shall be applied on. An example for best practice is to extract all humidity on and inside the parts used by drying them at approx. 50 C for about 1 hour, as otherwise the resin may form gas bubbles while curing. Hardener Voltatex 5131 respectively Voltatex 5132 shall be added to the casting resin in the mixing ratio stated above. The mixture has to be stirred homogenously and carefully without including foam. Voltatex 3110 and Voltatex 5131 resp. Voltatex 5132 can be applied on all common mixing and dispensing equipment with our without applying vacuum. Pot life Pot life of Voltatex 5131: approx. 40 min at room temperature Pot life of Voltatex 5132: approx. 50 min at room temperature Curing After curing of 48 hours at 20 C minimum the resin compound can be fully stressed (both mechanically and electro-technically).

3 Cleaning Once cured the resin compound is almost insoluble. Therefore, application equipment should be cleaned regularly with cleaner Voltatex All equipment cleaning and maintenance should be carried out in accordance with the equipment manufacturer s instructions. Delivery and storage Voltatex 3110 is supplied in non-returnable one-way containers of 20 kg and in 250 kg. Additionally 1000 kg containers (returnable) are available (not for oversea export). In closed original cans and at 25 C storage temperature maximum the resin can be stored for 12 months. The hardener can be stored for more than 6 months under the same conditions. Both resin and hardener have to be protected against water and humidity and therefore must not be stored outside. Additionally the respective hardener must be stored and transported frost-protected (above 10 C). Health & Safety Cured resin is biologically inactive and not dangerous to health. When processing the liquid components please refer to the respective Material Safety Data Sheets (MSDS s) and the regulations of your local authority. Voltatex 3110 Issue 03/ page 3 of 8
