Coathylene

Paints and varnishes

Coathylene powder additives can be used for:

- Anti-slip effect

- Structuring

- Matting

- Improving scratch resistance of a paint or a coating

Using Coathylene ultra-fine powder will reduce the gloss of the paint, and also provide an improved abrasion and scratch resistance.

Glass fibre reinforced plastics (SMC/BMC)

Glass fibre reinforced plastics are composite materials made from a polymer matrix reinforced by glass fibres. Pressed, finished parts are used in the automotive, aerospace and construction industries. Due to their mechanical stability, light weight and longevity they become an essential material for a very broad range of applications. For compounds such as SMC, BMC or pultrusion, Axalta offers high performance thermoplastic powder additives with following advantages:

- Anti-Shrink additive for low profile

- Improved surface finish and appearance

- Improved dimensional stability and mechanical properties

- A complete list of benefits is shown in the download flyer

Masterbatch

A Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heating process into a carrier resin, which is then cooled and cut into a granular shape. Using a Masterbatch allows the processor to homogenize raw polymer economically during the plastics manufacturing process. Masterbatches are made by dry blending ingredients with carrier resin, ideally in powder form. The key benefit of using a powdered polymer compared to granules is a more uniform dispersion. This shows as a higher color efficiency for color masterbatches, whilst keeping the pigment level, and hence cost, to a minimum. The major benefits are:

- Excellent pigment and additive dispersion

- Color efficiency

- Cost Optimization

Alkaline batteries

Coathylene thermoplastic powder may be used as binder for the cathode rings in alkaline batteries.

High cathode mechanical strength is one of the key factors in battery technology, as it determines production efficiency. By adding a small amount of Coathylene, the force required to break the cathode can be increased dramatically. The Coathylene powder is electrochemically inert, and hence does not have any influence on resistivity.

Flooring

Epoxy or PVC based materials are intrinsically brittle, which compromises their use in applications requiring flexibility and toughness. In order to increase flexural properties and impact resistance, Coathylene thermoplastic micro powders can be incorporated into the resin matrix. Coathylene powders also modify the flow characteristics of the system and reduce dripping.

Ceramic and metal parts

For ceramic and metal sintering Coathylene powders may be used as porosity agent and binder. The key benefits include:

- No residues after burning

- Various viscosity grades available

- Various particle size ranges available

Tooling block

Epoxy and polyurethane tooling blocks used for modelling and prototyping are brittle and can be severely damaged during the deburring step. If damage occurs during this critical phase, the tooling block is destroyed. In order to increase flexural properties and impact resistance, Coathylene thermoplastic micro powders can be incorporated into the resin matrix. This will increase resistance of the entire block, bring flexibility and consequently reduce the risk of damage during the moulding process.

3D printing (selective laser sintering)

3D Printing is an automatic method used for the manufacture of objects, models or prototype parts. This technology enables accurate prototypes in a complex shape to be manufactured, and in a reduced time. Different technologies are available, including Selective Laser Sintering using thermoplastic powders. With Coathylene Sint Series (Polystyrene or Polypropylene based) Axalta fulfills the technical requirements for this very demanding market:

- Very fine particle size distribution

- X50 = 45-60 microns            

- Excellent free-flow characteristics

- High dimensional stability

- No water absorption

- Ash content <0.01%

Toll manufacturing services

Micronization of a polymeric material extends the application fields and increases the processing windows significantly due to the higher specific surface of the materials in powder forms. Axalta offers several tolling services for the micronisation of thermoplastic materials, from pilot scale to production sized runs. We also have the analysis tools required to support your micronisation project.
