ARALDITE PT 910 ensures strong UV stability, outdoor durability, and long-term gloss retention in exterior applications.
Chemical resistance:
ARALDITE PT 910 enhances resistance against solvents, cleaning agents, moisture, and mildly corrosive environments.
Smooth surface finish:
ARALDITE PT 910 promotes good melt flow during curing and helps form uniform, smooth, and defect-free coating surfaces.
TGIC-free formulation support:
ARALDITE PT 910 enables the development of TGIC-free powder coating systems, supporting regulatory compliance.
Solvent-free compatibility:
ARALDITE PT 910 is suitable for VOC-free powder coating technologies and contributes to environmentally responsible formulations.
Processing stability:
ARALDITE PT 910 maintains consistent behavior during extrusion, grinding, storage, and electrostatic application.
High crosslink density:
ARALDITE PT 910 forms a tightly crosslinked polymer network, which increases mechanical strength and overall coating performance.
Properties of ARALDITE PT 910:
Polyester / ARALDITE PT 910 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 910 supplies a very attractive and consistent product quality profile including storage stability, appearance, curability, mechanical performance and over bake stability (especially in gas fired ovens).
Processing Data of ARALDITE PT 910:
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 910 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 910 powder, ARALDITE PT 910 is particularly advisable to blend silica or aluminium oxide anti-caking additives in order to ensure powder fluidity upon storage at elevated temperature.
