Flow Modifier Enhances Surface Appearance
Modarez MFP-A25P flow modifier for powder coatings was designed to address the surface imperfections, such as orange peel and craters, seen in low-temperature-cure systems for wood and plastic substrates. This silicone-free polymer works well in TGIC polyesters, epoxy hybrids and GMA-acrylic systems, and it can be used in both industrial and automotive formulations. It will not yellow during overbake conditions and delivers enhanced flow, smoothness and recoatability.

Texturing Agent Reduces
Gloss
PowderTex 61 crystalline fluoropolymer texturing agent produces consistent,
reproducible textures in a wide range of powder coatings. It provides good gloss
reduction and texture appearance at low concentrations. This processed
polytetrafluoroethylene produces satin gloss and controlled orange peel-type
textures in general metal finishes and coatings for OEM and aftermarket
automotive parts, farm equipment and electronics.

Hardeners Are
Compatible With Epoxy Resins
Aradur curing agents are suitable for use with Araldite epoxy resins to produce
coatings that are resistant to food, chemicals and fuels. Powder coatings
formulated with these hardeners can be used to protect oil and gas pipelines and
steel reinforcing bars. These products can also serve as an integral part of
special can gold lacquers and stain-resistant white enamels.

Sieve Reclaims Powder
Overspray
Model RVM-22E off-line gyratory sieve reclaims overspray and recovers virgin
powder coatings. This portable unit, vibrating at 3,600 rpm, can accommodate a
50-pound box of powder emptied directly onto the screen surface. Process rates
range from two to four minutes per box, depending on the type of powder coating.
Because the sieve has only two stainless-steel product contact parts, cleanup
and color changes are simplified. A self-feeding hopper allows the operator to
load a new container, while the processed coating is discharged into a clean
box.

Polyester Resin Yields
Low Gloss Coating
Fine-Clad M-8406 is a bi-functional polyester designed to cure by glycidyl-acrylic
hardeners and urethane cross-linker to yield high-performance matte and
semi-gloss powder coatings. When cross-linked with Fine-Clad A-266 acrylic
cross-linker, Fine-Clad M-8406 produces a super-durable matte finish with
excellent exterior durability, superior burnish and mar resistance, excellent
mechanical properties and film smoothness, a stable low gloss at varied
extrusion and baking conditions, as well as the ability to achieve various gloss
levels with formulating technique. Typical applications include automotive
parts, metal furniture and fixtures and aluminum extrusions.
