SynChem – Resins & Varnishes Voltatex® 2020 Alkyd finishing varnish
Voltatex® 2020 is a red or grey pigmented, air-drying, 1-c-finishing-varnish with espcially excellent adhesion to metals and plastics based on modified alkyd resin.
Pigmented varnish that dries fast in air with outstanding adhesion to metals and plastics, suitable as additional protection against external influences, particularly against moisture. Compatible with all common enamelled wires. Voltatex® 2020 has corrosion-protective properties. In combination with Voltatex® 1-c dipping resin the standards of DIN 5510-2 (preventive fire-protection in rail vehicles) can be fulfilled - depending on certain components and applications.
Application
Electrically-insulating finish on impregnated coils, windings and other components in electrical engineering and electronics.
Delivery forms
12.1 kg can or 20 kg barrel
Color
Red or grey pigmented.
Storage
Voltatex® 2020 can be stored at room temperature in sealed containers for 12 months (max. 25 °C). The varnish must be stored in a proper location protected from direct sunlight, UV radiation and sources of heat. Always observe the standard official rules and regulations.
Hardening
Curing is possible in explosion-protected environments beneath a fume hood under the following ambient conditions:
Air-drying times at 23 °C and 50 % rel. humidity:
0.5 h dust-dry
2 h touch dry
48 h entirely dry
Air-drying times at:
40°C - 20 h entirely dry
50°C - 16 h entirely dry
60°C - 3.5 h entirely dry
80°C - 1 h entirely dry
Protection
Cured Voltatex® 2020 is biologically inactive and not damaging to health. Always refer to the safety data sheet.
Cleaning
Equipment should be cleaned promptly using Voltatex® T023 solvent. Maintenance and care of coating plants, especially cleaning, must be carried out according to operational requirements. Always refer to the operating instructions of the plant.
Processing
Voltatex® 2020 can be used as dip coating, painting or spraying. Because the pigments and fillers of this varnish can sediment after long-time storage, Voltatex® 2020 should be well stirred before usage. In order to achieve an optimum viscosity up to 15 % Voltatex® T023 can be added.
