Paint knowledge | polyurethane paint classification

Core tip: polyurethane coating is a kind of common coating, which can be divided into two-component polyurethane coating and one component polyurethane coating Two component polyurethane paint -- wood paint coating is generally composed of isocyanate prepolymer (also known as low molecular carbamate polymer) and hydroxy tree ester, commonly known as curing agent component and main agent component It can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane and other varieties according to different hydroxyl components According to the type of packaging, it can be divided into single can polyurethane paint, double can polyurethane paint and three can polyurethane paint Three cans of polyurethane are usually used for home decoration Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: polyurethane coating is a common kind of coating, which can be divided into two-component polyurethane coating and one component polyurethane coating Two component polyurethane paint -- wood paint coating is generally composed of isocyanate prepolymer (also known as low molecular carbamate polymer) and hydroxy tree ester, commonly known as curing agent component and main agent component It can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane and other varieties according to different hydroxyl components According to the type of packaging, it can be divided into single can polyurethane paint, double can polyurethane paint and three can polyurethane paint Three cans of polyurethane paint (i.e one can of main paint, one can of curing agent and one can of diluent) are usually used for home decoration According to its composition and film forming mechanism, it can be divided into five categories: polyurethane modified oil coating, moisture curing polyurethane coating, closed polyurethane coating, catalytic curing polyurethane coating and hydroxyl curing polyurethane coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
