Coating classification: curing agent for PU matte surface

Core tip: Introduction: The curing agent for PU matte surface is suitable for PU matte finish series Characteristic: Pu curing agent for matte surface has high solid content, fast drying speed, good leveling, high hardness, good matte effect, pure odor, low toxicity and environmental protection, which is suitable for matte paint Deployment ratio: Pu matte finish: curing agent: diluent = 100:50: (70-80) Construction precautions: 1 When using each time, mix the paint from the bottom to the surface to ensure the unity of luster and color 2 During construction spraying, ensure that the base material is well polished 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: Introduction: Pu curing agent for matte surface is suitable for PU matte finish series of supporting curing agent Features: Pu curing agent for matte surface has high solid content, fast drying speed, good leveling, high hardness, good matte effect, pure odor, low toxicity and environmental protection, suitable for matte paint Formulation ratio: Pu matte finish: curing agent: diluent = 100:50: (70-80) Construction precautions: 1 When using each time, mix the paint evenly from the bottom to the surface to ensure the unity of luster and color 2 During construction spraying, ensure that the base material is fully polished, dry and clean, and remove sweat, oil, dust, etc., tools and equipment are fully degreased and dehydrated, and keep the environmental humidity not too high, so as to avoid rough, separated layer, shrinkage cavity, oil leakage and other adverse phenomena 3 During paint mixing, according to the site construction conditions, add a proper amount of special Pu bottom and mix evenly with diluent, and use it after placing for 10-20min During the use process, if the construction placing time is long, mix it fully in time before spraying 4 The paint shall be mixed reasonably according to the construction amount The mixed paint shall not be placed too long The longer the time is, the more the gloss will decrease After mixing, each component and the prepared coating shall be sealed in time to avoid deterioration and pollution 5 Before spraying, filter with a filter cloth of more than 300 meshes During spraying, the gun should be evenly run, and it should not be too thick at one time In order to obtain a thick paint film, thin spraying should be carried out many times 6 During paint preparation, the amount of curing agent should not be increased or decreased excessively to avoid affecting the luster, hardness, etc 7 When the temperature of the environment is high, 5-20% of the slow dry water can be added properly, which can eliminate the bad phenomena such as orange peel and poor leveling 8 The viscosity of paint changes with the change of temperature, decreases with the increase of temperature, and increases with the decrease of temperature When the temperature is low, the viscosity will increase a lot, which will cause the diluent to increase At this time, the gloss and fullness of the paint may be affected (decreased) 9 If it is to be recoated after drying, it shall be fully polished before spraying, so as to avoid separation, fogging, shrinkage, oil leakage and other phenomena 10 The amount of diluent shall be properly adjusted according to the different construction environment, spray gun diameter, temperature and humidity, and spraying thickness, so as to make it easy to spray construction, level well and do not hang 11 Use supporting curing agent and diluent 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,
