- Uses
Phenodur VPW 1946 is a formulated phenolic/epoxide resin, intended as a sole binder for corrosion resistant industrial stoving systems. When compared to Phenodur VPW 1942, VPW 1946 cures at lower temperatures.
For spray applications, Phenodur VPW 1946 has to be diluted with water in the usual ways. For applications on roller coaters, the viscosity should be increased by means of thickening agents and/or organic solvents. In both cases, additions of organic solvents like hexylglycol improve flow and surface wetting and reduce the tendency of a quick physical drying.
The usual stoving cycle is 10-12 min at 170 - 200 °C, "shock curing" is possible. The cured films at a thickness of approx. 5 µm exhibit a golden color and very good adhesion, corrosion protection, flexibility and solvent resistance.

Technical Details & Test Data
- Dilutabilty
Phenodur VPW 1946 is unlimited dilutable with deionized water. In order to improve flow and leveling properties, organic solvents such as glycol ethers and alcohols can be added to the formulation.
- Compatibility
Phenodur VPW 1946 is designed as a sole binder, the compatibility with other resins is limited. Combinations with other polymer dispersions and water-dilutable melamine resins are possible, storage stability and compatibility have to be tested in advance. Such additions of other resins might influence the rheological behavior of Phenodur VPW 1946 greatly.

- Storage and Handling
At temperatures up to 25 °C storage stability packed in original containers amounts to at least 730 days.
It is important to protect Phenodur VPW 1946/46WA from frost; at low temperatures it has therefore to be stored under frostproof conditions.
