Here the resin / hardener mixture is stirred very carefully and decanted in a clean mixing vessel and stirred again. Use instruction: 1. Background: on wood normally light grinding is enough; on polyester- or two component primer the surface must be ground before application. on metal the surface must be sand-blasted and the primer or plastering must be used within 2 hours to prevent an oxidation of the surface.. 2. Consider the temperature of the support. It must be higher than the dew point to prevent a condensation of moisture between the layers. 3. Work in a shadowy area, protected from rain or dew, in good ventilated rooms and at temperatures above 15 C. 4. Use fresh products on jellied material resp. fresh products on hardened material which was ground before. Normally hardening and post-curing isn t necessary. Storage recommendation: At proper storage the shelf life of epoxy resin and the corresponding hardener is 2 years, if both are stored in sealed original containers, in dry and cool rooms Precautions whilst handling: Read the safety data sheet and comply with regulations referring work protection and disposal.

Add the corresponding quantity hardener and resin and mix carefully. An extremely good mixing will be achieved by repotting. Thereby the resin/hardener mixture is stirred carefully, filled in a clean mixing vessel and stirred once again. Whilst preparation of the surface (mould resp. model) please adhere to the separating agent data sheet. Hardening / post-curing: Post-curing is always recommended at RT hardening systems, to stabilize the component on the one hand and to achieve the best mechanical characteristics on the other hand. Although this system already reaches a higher thermal resistance at room temperature than the common systems, it is post-cured at a temperature of around 60 C and so it s possible to achieve a good thermal resistance. Hardening and post-curing should be made before use to give the necessary thermal resistance to the mould. Whilst post-curing the component should heat step by step around 10 C/h. The user should evaluate the best conditions for hardening resp. post-curing depending on the size and shape of the component. At bit components you should reduce the thermal gradient and increase the post-curing time. At thin layers and composites make post-curing on a clamping device. Storage recommendation: At proper storage the shelf life of epoxy resin and the corresponding hardener is 2 years, if both are stored in sealed original containers, in dry and cool rooms. Since the hardeners are moisture sensitive it s recommended to close each package again at once after use.

10 Hardening / Post-curing: Post-curing is always recommended at RT hardening systems to stabilize the component on the one hand and to achieve the best mechanical characteristics on the other hand. This is necessary when the component is used at high temperatures. The level of the temperature and the indicated post-curing time refer to standard sample sizes. Depending on size and shape of the component the user should appreciate the best conditions for hardening resp. post-curing. At large components the thermal gradient should be reduced and the post-curing time increased. At thin layers and composites make the post-curing on a clamping device. As general guidance to reduce the risk of thermal deformation we recommend to make the post-curing as follows: In moulds: 24 h RT + 6 h 40 C + 6 h 50 C + 6 h 60 C + 12 h 70 C Outside the mould but in the clamping device: 7 days RT + 6 h 50 C + 6 h 60 C + 12 h 70 C. The glass transition temperature under these conditions is near the max. Tg. Storage recommendation: At proper storage the shelf life of epoxy resin and the corresponding hardener is 2 years, if both are stored in sealed original containers, in dry and cool rooms. Since the hardeners are moisture sensitive, it s recommended to close each package again at once after use.
