What pigment is used for wall painting?

Propylene pigment is a synthetic polymer pigment, which was invented in 1950s and made of pigment powder and acrylic latex. Acrylic latex is also called acrylic polymer latex. There are many kinds of propylene resins, such as methacrylic resin, so there are also many kinds of propylene pigments. Foreign pigment manufacturers have produced a series of propylene products, such as matt propylene pigment, semi-matt propylene pigment and glossy propylene pigment, as well as propylene matt oil, varnish and plastic ointment.

Acrylic pigments are very popular with painters. Compared with oil painting pigments, it has the following characteristics:

(1) can be released by water, which is beneficial to cleaning.

(2) Quick drying. Pigment can be dried in a few minutes after putting pen to paper, instead of waiting for months to polish it like oil painting. Painters who like slow-drying pigments can use retarders to delay the drying time of pigments.

(3) After drying, the colored layer will quickly lose its solubility and form a tough, elastic and impermeable film. This film is similar to rubber.

(4) The color is full, dense and fresh, and no matter how blended, it will not feel "dirty" or "gray". The color layer will never be stained by oil absorption.

(5) the durability of the work is long. The oil film in oil painting is easy to oxidize, yellow and harden, and it is easy to crack the picture after a long time. Theoretically, acrylic films will never become brittle and yellow.

(6) The biggest difference between acrylic pigment and oil painting is that it has the operational characteristics of general water-based pigment, which can be used as both watercolor and gouache.

(7) There are particles, coarse particles and fine particles in the acrylic plastic ointment, which provides convenience for making texture.

(8) Propylene pigment is nontoxic and will not cause harm to human body.

It should be noted that acrylic painting should be painted on the base made of acrylic primer (gypsum), and oily base painting cannot be used. Material experts also don't advocate the mixed use of propylene and oil painting colors, especially don't paint oil paintings on propylene base, mainly for the permanent preservation of works. Propylene has no adverse reaction with oil painting pigments, and its adhesion needs time to be tested when it is used alternately.
