APPENDIX 5 Reference
TYPES OF HARMONIOUS COLOR COMBINATIONS

1. The use of the color of paints and varnishes to create the appropriate color solutions for products is determined by the psychological (emotional) and physiological impact of individual colors and color combinations on a person.

When choosing color combinations of coatings, their harmony should be the first and main condition.

2. To obtain harmonious color combinations, it is necessary that there is a certain relationship between the colors (contrast or similarity between colors in hue, lightness or saturation).

3. The relationship between colors is achieved using the principles of choosing color combinations on the color wheel (Fig. 1).

Color circle

F - yellow; ZhO - yellow-orange; O - orange; KO - red-orange; K - red; P - purple; FP - violet-purple; F - purple; C - blue; SZ - blue-green; З - green; ZhZ - yellow-green; I, II, W, IV - color zones

Heck. one

4. When choosing color combinations, the characteristics of four psychological optimal primary colors - yellow (221), red (7), blue (427), green (324) and intermediate - orange, violet-purple, yellow-green - are taken into account.

5. Color combinations are divided into five main groups according to psychophysiological characteristics: contrasting, related, related-contrasting, equitonal, complex.

9. The car is operated in atmospheric conditions of a temperate and tropical climate, it is contaminated with road dust, dirt and is subjected to periodic washing with hot and cold water using brushes. The overhaul period is 3 years, and the car is maintained on a permanent basis.

10. The specified operating conditions are satisfied by paint and varnish coatings obtained on the basis of ML-12 melamine-alkyd enamel, KhV-110 perchlorovinyl enamel.

The coating system, consisting of two layers of ML-12 enamel, applied to the primed surface, is stable in atmospheric conditions of temperate and tropical climates for 3 years.

The coating system, consisting of two layers of XB-110 enamel, applied to a phosphated and primed surface, is also stable in temperate and tropical climates for 3 years.

11. In terms of color, texture, gloss and class of enamel ML-12 and XB-110 meet the requirements: enamel color ML-12 orange (121, 128), enamel XB-110 yellow (285, 286), coatings according to the recommended - smooth , glossy (ML-12), semi-gloss (XB-110), the maximum achievable coating class II for ML-12 enamel and III for XB-110 enamel.

12. Taking into account the level of production of the painting area (production - serial, painting on flow conveyors by pneumatic spraying or spraying in an electric field, drying in thermo-radiation drying chambers at a temperature of 130 ºС), you should choose ML-12 enamel, which is applied by the specified method and has a mode thermo-radiation drying at a temperature of 130 ºС for 20 minutes.

PAINT COATINGS

Paints and varnishes (oil and enamel paints, as well as nitro enamels) are used for protective and decorative purposes.

Oil paints, prepared with oils and drying oils, are produced in different colors in a pasty form. Before use, they are diluted with linseed oil to a working viscosity and applied to the product with a brush or spray bottle. Oil paint coatings have a low gloss.

Enamel paints are prepared on varnishes; distinguish between oil enamels, alcohol and nitro enamels prepared on varnishes of cellulose ethers.

The enamels are produced ready-to-use. Oil enamels are applied with a brush or a spray bottle, and nitro enamels - mainly with a spray bottle, as they dry quickly.

Enamel coatings are distinguished by good gloss and increased hardness, resistant to temperature changes from -40 to + 60 ° C.

GROUPS, TECHNICAL REQUIREMENTS AND CLASSES OF PAINT COATINGS

GOST 9.032-74 applies to paint coatings (hereinafter referred to as coatings) of product surfaces and establishes groups, technical requirements and designations of coatings.
