SynChem – Resins & Varnishes Voltahyd® 2220 Polyacrylate Coating Varnish
Voltahyd® 2220 is a red pigemented, water based hybrid resin.
Voltahyd® 2220 is a water-based, ready to use, quick drying and pigmented topcoat with good adhesion to steel, galvanized substrates and aluminium. It is suitable for additional protection against external influences, especially against humidity and corrosion. Voltahyd® 2220 has also a good adhesion to impregnating resins* respectively on impregnated goods.
*tested on styrene based impregnating resins

Red
Storage
A temperature range of above 5 °C and below 35 °C is recommended as storage temperature. As Voltahyd® 2220 is a water-based product, it must be protected against frost! In orginally closed delivery items, the product has a shelf-life of 6 months. Opened containers have to be closed tightly after material withdrawal!. We recommend storing the product between 20-25 °C.
Hardening
Air-drying at room temperature (20-25 °C) is preferred for this product:
- 45-60 min tack free
- 2-3 h touch dry
- 24-36 h ready to assemble
Accelerated drying:
- 60-70 °C: 2-3 h ready to assemble
Protection
Voltahyd® 2220 is intended for industrial / professional usage only. For further information please refer to the safety data sheet.
Processing
The coat can be applied to the object by dipping, brushing or spraying. Since the pigments and fillers contained in the coating may settle over time, Voltahyd® 2220 should be thoroughly stirred before application. Adding Voltatex® T041 is possible to adjust the optimal processing viscosity of Voltahyd® 2220.
