Surface Adjusting Additive MFA-08

Surface Adjusting Additive For Metal Powder Coating MFA-08A


■ Introduction

Surface Adjusting Additive For Metal Powder Coating MFA-08 is an compound multifunctional additive which use for the various metal powder coating bottom powder , with leveling, dispersion, wetting, defoaming, improve the system compatibility and other characteristics. Can replace leveling agent, wetting accelerator(or brightener),benzoin,wax powder and other additives in the formula, help to eliminate the bottom powder’s shrinkage cavity and improve the film’s black dot for the metal powder coating also meet the RoHS requirement.


■ General Character

Appearance: ....................................................................White powder or granules

Non- volatile(%):................................................................. ≥99.5%

Apparent gravity (g/cm3):....................................................0.8-1.2

Active components(%):..................................................... ...85-90%


■ Features

●Provides excellent flow and leveling properties and improve the coating’s fullness;

●It can help get rid of bubble and pinhole on the coating;

●Good anti-interference ability ,reduce the melt viscosity in the molten/curing process,adjust the surface tension,help to eliminate the bottom powder’s shrinkage cavity and improve the film’s black dot for the metal powder coating;

●effectively improve the coating’s tarnish resistance and chemical resistance ability;

●Effectively improve the coating surface hardness and scratch resistance property;

●Good temperature resistance and yellowing resistance property;

●Can effectively improve the coating’s adhesion and impact strength resistance and other physical mechanical property;

●Outstanding pigment wettability to help disperse the pigment;

●Good compatibility and processing performance;

●Can significantly improve the paint loose, flow, smoothness and stable storage property;

●Perfect anti-static property, improve the powder ratio;

●No impact on the re-coating;

●Used for matte formula, no impact on the matting;


■ Usage

Applied in pure epoxy, epoxy polyester, polyester TGIC(HAA), polyurethane, acrylic acid and other thermosetting powder coating formula, not limit on gloss.


■ Use Method

●Recommended dosage: 2% to 4% of total formula, usually 3%, but different equipment with different dispersion effect, the best dosage should be based on the individual test. In general, when the equipment dispersion is not good enough, please consider to increase MFA-08 dosage.


●Usage:

MFA-08 should evenly dry mix with other materials in the formula, and heat melting and mixing extrude, pay attention to the parameter settings.
