Type: Enamel is a suspension of pigments in alkyd melamine varnish with the addition of organic solvents and functional additives.
Scope: Enamel is intended for painting primed metal surfaces, including parts for bicycle, motorcycle and other products, and to obtain a coating with a metallic effect.

Benefits: Enamel provides a highly glossy finish with a metallic effect. Enamel coatings have high decorative properties when used in atmospheric conditions and indoors. The enamel coating is minus 60 ° C to plus 60 ° C.
Surface preparation: Before applying the enamel, the primed surface is sanded, dedusted, degreased and dried thoroughly if necessary. The surface is mechanically cleaned, dehydrated, degreased and dried. The temperature should not be below 3 ° C. Recommended primers: EP-045,
EP-045K (TU BY 5000021625.106), GF-0119 (GOST 23343) produced by Lakokraska.
Recommendations for application: Enamel is applied to the primed surface using pneumatic and electrostatic spraying. When tinting small areas of enamel can be applied with a brush.
Before use, the enamel is thoroughly mixed and, if necessary, filtered. When applied by pneumatic spraying, the enamel is diluted with xylene (GOST 9949 or GOST 9410), orthoxylene
(TU BY 300042199.015) or thinner P-197 (TU 6-10-1100) in an amount of 18 – 25% by weight of undiluted enamel, when applied by electrostatic method sputtering – RE-2B diluent (GOST 18187) in the quantity necessary to achieve specific volume electrical resistance in the range from 5 · 104 to 5 · 105 Ohm · m. When applied with a brush, the enamel, if necessary, is diluted with xylene
(GOST 9949 or GOST 9410), orthoxylene (TU BY 300042199.015) or thinner P-197 (TU 6-10-1100) in an amount of not more than 5% by weight of the undiluted enamel.
The temperature is between 15–25 ° C and the temperature of (20 ± 2) ° C and final drying a temperature of 130 to 135 ° C within 30 min. After drying, should not be at least 40 microns.
Of The ENAMEL consumption for a to two two-dried coating of layer with a thickness of
30–40 µm is 70–100 g / m² without reference to the preparation of the personnel and other factors.
Enamel Coating Service life: A coating system applied on a primed surface (primer EP-045
(TU BY 5000021625.106) 10-15 microns thick for 1 year.
