Datenblätter
The raw rubber requires the addition of a platinum catalyst for vulcanization at elevated temperatures. A homogeneous incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior. Pot life is depending on the used catalyst and storage condition.
ELASTOSIL® R plus 5305/70 and ELASTOSIL® AUX PT 1 are homogeneously mixed in a ratio of 100 : 1.5. Care must be taken to keep the compound cool during mixing. Crosslinking begins when ELASTOSIL® AUX PT 1 has been added. The rate and degree of crosslinking depend on the storage time and temperature. At 23 °C the mixture has a pot life of about 24 h. This can be extended by storing the catalyzed mixture at a lower temperature.
For detailed information please refer to the latest edition of our brochure "SOLID AND LIQUID SILICONE RUBBER - MATERIAL AND PROCESSING GUIDELINES".
Verpackung / Gebinde
This product is available in 20 kg and 540 kg cardboard packaging.
Special delivery forms are possible but depend on several technical and commercial aspects. Please contact your local sales manager in such cases.
Lagerung
Once opened, cardboard boxes should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
