Gloss Control With Confidence

Gloss Control with Allnex RESINS

Resins for every aspect of
Powder Coatings Gloss Control

allnex offers a broad range of performance polyester resins and additives for adjusting the gloss levels of powder coatings

The allnex Gloss Control palette

The CRYLCOAT®, SETAPOLL™ and SYNTHACRYL® polyester and acrylic products range from allnex offers resins for every gloss level for all aspects of Industrial and Architectural Coatings. Our polyester resins are designed to cure with all the major crosslinker groups: hydroxy-alkylamide (HAA), triglycidylisocyanurate (TGIC), glycidylester and isocyanates (PU).

Compared to hybrid powder coatings, the efficiency of common matting methods like adding fillers and matting aids to outdoor powder coatings, often results in a reduction of matting control. Most popular gloss levels of approximately 35±5 GU, 25±5 GU and even dull matte (<10 GU) are achievable only by the following methods:

  1. Matte Dry Blend (or 2 Component) Systems where two different individual powders are prepared that differ in reactivity and viscosity. Mixing of the two together leads to a controlled incompatibility and consequently to a controlled low gloss of the final finish.
  2. One Shot Matte (or Single Component) Systems where two individual resins of different functionality, reactivity and/or viscosity are combined together before the extrusion process. This method provides almost the maximum in gloss reduction but cannot be applied for all chemistries.

A whole variety of factors can influence the effect, specific pairs of resins provide unique performances to meet market demands in various coatings segments.

In practice there are often cases where it is desirable to reduce the curing temperatures or to shorten cure times of powders. That’s the moment so-called catalysts come into play. They have the ability to reduce the activation energy of the curing process and can exactly fulfill this requirement. In the form of a masterbatch powder coating, manufacturers are able to easily disperse a relative small amount of highly active catalyst into the bulk of the powder and to achieve an even effect.

The active ingredient is optimized to facilitate the conversion of the reaction between carboxy and epoxy that is the base for the curing process in hybrids and outdoor durable powders with TGIC and Glycidyl esters as hardeners. ADDITOL P 964 and ADDITOL P 966 are two masterbatches containing 10% of active ingredient on a carboxyl functional polyester carrier resin that will be built into the polymer backbone during the curing process. ADDITOL P 964 is based on a standard durable polyester carrier resin and is widely used in hybrids and TGIC formulations whereas ADDITOL P 966 has a superdurable polyester resin as carrier and is preferably added in superdurable coatings systems.

Preferred matting methods for outdoor durable powder coatings are matte dry blend (MDB) and one shot matte (OSM) formulations. For both methods the matting mechanism is mainly based on differences in reactivity of the components. The addition of catalysts to a high functional, fast reacting component can enlarge the delta in reactivity and hence provide a further down-glossing. In this way a certain resin combination can cover a whole range of different gloss levels.

Advantages of Powder coating

Very environmental friendly

Powder coating enhances the appeal and longevity

Re-useable powder coating overspray

High heat and chemical resistance

Powder coating can be applied directly to the substrate (primers not needed)

Minimal powder coating waste

Powder coating is used to finish a vast variety of applications like architectural, furniture, agricultural and construction equipment, as well as household appliances.

Unlike liquid paints and coatings that are delivered through the evaporation of a solvent, powder coating is typically applied electrostatically, melted and cured under heat. Thermosetting powder coatings are usually based on functional, solid polyester resins as binder combined with hardeners, pigments and fillers. Modern polyester resins enable formulators to meet all requirements of high quality coatings in many application segments.

Applied as dry powders, the coatings are excellently suited for applications on metals like automobile parts, aluminum extrusions, household appliances, furniture as well as agricultural and construction equipment. Powder coatings show high heat, corrosion and chemical resistance, great hardness and flexibility. Furthermore, the coating process releases few to no volatile organic compounds (VOCs) rendering powder coatings an excellent choice for indoor and outdoor applications. Excess powder can also be collected and re-used to minimize product waste and pollution of surrounding areas.
