FLOWING AGENT TP88 for powder coatings
The powder flow modifier TP88 equivalent to worleee resin flow PV88 can be applicable to any powder coating systems such as EP.PES/EP hybrid, PES/TGIC.PES/Primid and PU etc.
1. Properties
Appearance free flowing white powder
Active contents(%,wt) ＞＝65
Volatileness, (%wt) ＜＝4
Bulk density,(g/cm3) 0.58－0.64
2.The name of molecular : Sio2 + polybutylacrylate
3．Advantages
Be applicable to any powder coatings therefore no considering its comportibility with adove coatings.
Provides superior flow, leveling and dispersing properties in powder coatings.
Decreases probably the cost of powder coatings due to the less added amounts in the formulations than that of normal flow modifiers such as the form of mastarbatch resins based on epoxy or polyester.
Can be post added a wide range of powder coatings to impart fine texture finish
4. Incorporation
TP88 can be added at the premix stage of powder coating manufacture and extruded with the other components of formulation by any suitable extruder then grinding ,but for post addition
It must to be incorporated into the final coating powder by dry blending way.
5. Usage level
its optimum usage level will be determined by yours thorough experiments
as a rule, at concentrations of 1.0~1.2% based on the total weight of the formulation, Bat for post addition, at 0.7~2.5% depend on the finishing formulations.
6. storage
store in cool dry place to avoid moisture absorption, keep away from fire.
7. package
Packaging with PE bag lined fiber drums, Net weight 25kg per drum
