Question

37. Constituent of paint that gives random arrangement to pigments is​

Answer 1

Explanation:

Pigments are finely ground natural or synthetic, insoluble particles used to impart color when added to paints and coatings formulations. They are also used to impart bulk or a desired physical and chemical property to the wet or dry film. Some of the main pigment classes include:

Organic pigments

Inorganic pigments

Functional pigments

Special effect pigments

While organic pigments do not disperse easily and form agglomerates (clumps of pigment particles), inorganic pigments get more easily dispersed in the resin. Functional fillers impart a desired property to the coating like corrosion inhibition and special effect pigments create optical effects like metallic, hammer finish and diverse color perceptions depending on the angle.

Answer 2

The constituent of paint that gives random arrangement to pigments is​ a resin

• A form of binder called resin gives the paint its desirable viscosity and sticky characteristics by holding the pigments together.
• There are various types that can be employed such as alkyd resins, polyester and acrylic etc.
• The resin naturally forms a seamless covering around the hues when it is added to the paint, assisting in spreading them out uniformly and preventing them from clumping.
• As a result, the pigments are ideally arranged more randomly and the paint has a more homogeneous appearance.
• The choice of resin depends on the type of paint being produced, the desired paint properties and the manufacturing process.
• In general, the use of a resin can improve the durability, hardness, and flexibility of the paint, as well as its resistance to cracking, peeling, and fading.
