Process treatment of polymers
- in wet or dry form
NAST® supplies customized surface coatings in one significant segment of applications.
Our surface processes of improved performance also increase the lifetime of components used in a large market every single day.
A large variety of industrial and consumer-related finished applications or semi-finished products continuously flows through our processing plant and satisfies individual levels of use.
NAST® advanced processing plants are equipped with water compatible coating lines consisting of multi-point process and equipment controls that ensure 100% compliance and repeatability.
Finished products consisting of conveyor lines with individually temperature-controlled curing ovens which enable parallel application processes to take place at the same time and at all times serve our customers with shortened delivery times.
Parts of our processing plant for dry form polymer as well as wet coating are also ready to process product units with significant weight and lengths.
R2R process
Semi-finished products are served through process lines for Coil (R2R) in width dimensions from 140 mm to 1500 mm in material thicknesses from 0.08 to 1.5 mm. Technical surface treatment covers a considerable range based on the area of application, be it organic (food- safe) nano chemistry for packaging purposes or other industry-oriented purposes based on other environmental impacts.
Advanced process lines handle single or double-sided surface treatment in a parallel process. Process lines have incorporated processing stations where coils are largely changed into dimensioned plate products.
Optimally adapted processes
Our processes are adapted for each individual substrate with the corresponding degree of use.
Fully staffed research and development team
Our experienced research and development team determines chemistry formulations and processing techniques, as well as performance and quality testing procedures specifically designed for the substrate being coated.
Conscious ability to meet exact requirements
We have the expertise to overcome technical challenges related to surface coatings thanks to our ability to control the use of fine particles, granules on the surface of a treated substrate. Ideal for materials whose performance requirements depend on surface composition more than the underlying substrate, and materials that require high value additives on the final product.
Each metal substrate has its own specifications
Optimal surface engineering solutions are available for every case of standard products as well as innovative technology and design. The purpose of surface treatment is to increase the product's corrosion resistance, wear resistance, friction ratio, aesthetics, or other functional requirements.
The development of sustainable solutions for surface engineering is necessary for the modern industrial sector where process parameters and chemical substances should be carefully selected to meet the demand for environmentally friendly technologies.
Prerequisites for achieving a successful surface treatment is the essential first stage treatment of a metal substrate.
This pretreatment process should not only clean the metal, but also add a custom profile to receive the protective coating.
Each metal requires its own, specific method to achieve optimal bonding to the polymer- coated surface structure, where we recommend with our knowledge what is required to secure the product, whether it is machined, otherwise processed or contaminated.
Suitable passivation procedure for each metal substrate and passivation of different metals is an important part and has a major focus in our business.
