Dow introduces a family of Superwetter Additives for high-performance water-based and UV cured inks, coatings and overprint varnishes:

  • DOWSIL™ 67 Additive
  • DOWSIL™ 500W Additive
  • DOWSIL™ 501W Additive
  • DOWSIL™ 502W Additive

Do you have difficulty achieving effective substrate wetting with your waterborne or UV cured formulations, particularly on challenging substrates like wood, plastic and metal? Have you tried other silicone additives, only to see undesirable effects on slip properties?

With its range of functionalities and hydrophilicities, the new family of superwetter additives from Dow can be used in waterborne, solventborne and solventless radiation curable coatings. These additives can help you obtain the wetting performance you want for your formulation and substrate – and do so with little or no impact on slip properties.

Making an informed choice of Superwetter

Dow understands that every formulation is different. By providing more information about structure, end capping and hydrophilicity/HLB, Dow seeks to improve the quality of wetting additive choices. All four products in this DOWSIL™ Superwetter family are 100% silicone polyether copolymers and are characterized by being usable in both waterborne and UV coatings formulations, offering recoatability and a high level of consistency across different types of binders.

In addition:

DOWSIL™ 502W Additive 100 49-75 13.2 OH 22.4

Key features of DOWSIL™ 502W Additive

Besides excellent wetting performance at low addition levels, DOWSIL™ 502W Additive can be used when consistent low dynamic surface tensions under shear is required, which could provide benefits in high-speed coatings or printing and spray coatings.

High performance at low use levels

DOWSIL™ 67 Additive, DOWSIL™ 500W Additive, DOWSIL™ 501W Additive and DOWSIL™ 502W Additive provide excellent wetting performance at low addition levels with little or no influence on slip. In a waterborne PUD-based flooring coating, for example, all four additives provide excellent wetting performance versus competitive organic and silicone wetting additives over different substrates. The toolbox approach also enables formulators to choose the right product for a specific application, while at the same time reducing the number of products they must maintain in their raw material portfolios. The superior performance can be measured in multiple waterborne coatings by the surface appearance and coefficient of friction (Figures 1 and 2).

High performance in high speed applications

DOWSIL™ 502W Additive can be used when consistent low dynamic surface tensions under shear is required, which could provide benefits in high-speed coatings or printing and spray coatings. When the dynamic surface tension is measured using a bubble tensiometer, DOWSIL™ 502W almost maintain its ST even at higher speeds. This gives an indication that DOWSIL™ 502W will be useful for wetting in high speed applications.
