Due to the contents of fillers which will settle to the ground during a longer storage period Voltacast 3200 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 Voltacast H132 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 Voltacast H132 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. Provided the product shall be blended with extra fillers, these fillers must be completely dried prior to adding them to the casting resin.
Best practice to add fillers to the product is to add the respective amount slowly and to stir the product until a homogenous mixture is ensured. The same way it is useful to heat up the mixture moderately to 60 °C or to establish vacuum in order to accelerate the degasing as mentioned above. Voltacast 3200 can be applied on all common mixing and dispensing equipment with or without applying vacuum.
