Properties of ARALDITE PT 912:
Polyester / ARALDITE PT 912 coatings exhibit a very compact structure.
Owing to the pure addition mechanism of the crosslinking reaction, no volatiles are released; therefore coatings are obtained, which are free of pores and voids of any kind.
Such coatings can be processed without any severe cure window or film thickness limitation.
There is no lack of adhesion, e.g. between coating layers (re-coatability) or with sealants.
When formulated with suitable polyester resins, ARALDITE PT 912 supplies a very attractive and consistent product quality profile including storage stability, appearance, curability and over bake stability (especially in gas fired ovens).
Processing Data of ARALDITE PT 912:
A very intensive homogenisation of the binder components upon premixing and extrusion processing is required to achieve the desired product quality.
Due to the large viscosity gap between ARALDITE PT 912 and the suitable polyester resins in the typical extrusion temperature range, i.e. 90-140°C, a relatively high shear is needed to ensure a homogeneous mixture.
Single-screw as well as twin-screw extruders are suitable.
Screw configuration and extrusion parameters are to be set according to the manufacturer’s guidelines.
Owing to the strong relaxation, which takes place in a freshly made Polyester/ARALDITE PT 912 powder, it is particularly advisable to blend silica or aluminium oxide anti-caking additives in order to ensure powder fluidity upon storage at elevated temperature.
