The perfect addition: top coats

The requirements for topcoats are high; as a result, Doerken Corporation offers a large range with different characteristics.

TOPCOATS – THE PRINCIPLE

Topcoats complement the characteristics of the basecoat or galvanic substrate: they increase corrosion resistance. However, their primary tasks are set coefficient of friction, chemical and mechanical resistance and color etc.

All products with integrated lubricant (GZ) have a set coefficient of friction, variously customized to different market requirements with the different coefficient of friction windows.

  • 0.09-0.14 µtot at VDA & VW
  • 0.11-0.17 µtot at Ford
  • 0.10-0.16 µtot at GM and
  • 0.12-0.18 µtot at PSA/Renault or the
  • K-factor 0.18-0.21 at Hyundai-Kia.

YOUR REQUIREMENTS: RESISTANCE TO MEDIA

Do you require topcoats with a high resistance to media such as chemicals and fertilizer? The use of selected acrylic, epoxy and polyurethane resins ensures that our topcoats deliver outstanding resistance to various different media with corresponding coverage/curing.

OUR SOLUTIONS:

DELTA®-SEAL variants, the black DELTA-PROTEKT® VL 450 or DELTA-PROTEKT® VT 600, but also the silver DELTA-PROTEKT® VL 411 GZ.

YOUR REQUIREMENTS: RESISTANCE TO WEATHERING

Resistance to weathering, such as UV effects, represents a different requirement. Here we use bonding agent systems that are not destroyed by UV exposure. This allows us to do away with the need for normal organic epoxy resins as well as other typical components, as these begin to chalk when exposed to UV rays, resulting in the destruction of the film or at least yellowing. Combinations of different bonding agents (such as acrylic and polyurethane) are used to achieve an optimal result with regard to appearance and function.

OUR SOLUTIONS:

The black DELTA-PROTEKT® VL 450, specially developed for weather resistance. Or the white DELTA-PROTEKT® VL 420.

YOUR REQUIREMENTS: SCRATCH RESISTANCE

If a coating is required for especially high scratch resistance, we use a very hard, low-molecular bonding agent as the basis for the coating. These bonding agents form a highly stable and close-knit network, which prevents damage to the film.

OUR SOLUTIONS:

DELTA-PROTEKT® VH 340 or a DELTA® -SEAL variant.

THE PERFECT COATING FOR YOUR APPLICATION

The choice of the coating system best suited to you is a complex one. We are therefore always ready to help with advice and assistance. Simply tell us your specifications and we will be happy to find the matching solution for you, including color, gloss, adhesion etc. If we do not have a suitable product in our portfolio, we will also develop an individual one for you.

  • DELTA-PROTEKT® VH 301.1 GZ sets new standards on the market: it enables multiple tightening against different surfaces with just one finish and prevents loosening under temperature. This makes it a tribological premium product.
  • The black topcoat DELTA-PROTEKT® VH 321 GZ combines an attractive appearance with the highest requirements regarding fastening properties and corrosion protection. In addition, in combination with the DELTA-PROTEKT® KL 120 basecoat it is scarcely susceptible to white rust.
  • The teflon-based deep black DELTA-PROTEKT® VT 600 has excellent sliding properties and is an alternative to classic sliding lacquer. In addition, it also reliably reduces squeaking in different installation situations. It is often used for purely optical reasons: it is deep black and glossy.
  • The DELTA-PROTEKT® VH 340 seal combines organic and inorganic benefits. It is watery, silvery and extremely scratch resistant. This makes it an ideal solution for large components – although it can also be used for dip spin applications with bulk products.
