thermosetting resins
Instructions:
In pre-filled products it is a good practice to check and carefully rehomogenize the material if some settlement is present. Add the proper quantity of the hardener to the resin, mix carefully. Avoide air trapping. For some applications it can be useful pre-heat the components and/or carry on a dearation step under vacuum of the mixture before casting.
Post-curing
For room temperature curing system the post-curing allows the fast stabilization of the material and the obtainment of the best electrical and mechanical properties. For hot curing systems it is advisable to follow the indications reported in the present data sheet verifiyng the correctness for the components under development. During curing process it is advisable to avoid thermal variations higher than 10°C/hour.
Storage:
Filled epoxy resins and relative hardeners can be stored respectively for one year and two years in the original sealed containers stored in a cool and dry place. After that period, or if the material has been stocked in anomalous conditions, pre-filled resins can be settled down and their use is possible only if they are accurately re-homogenized with the help, if necessary, of a mechanical mixer. The hardeners are moisture sensitive therefore it is a good practice to close the vessel immediately after each use.
Handling precautions:
Refer to the safety data sheet and comply with regulations relating to industrial health and waste disposal.
The information given in this publication is based on the present state of our technical knowledge but buyers and users should make their own assessments of our products under their own application conditions.
