Is there an additive and thinner for architectural coatings?

Due to the large difference between the use of water as a medium and solvent-based industrial coatings, the main aspects are as follows: the influence of surface tension: the surface tension of water is higher than 72 dynes, so it is much higher than that of general solvents, resulting in a large difference in construction effect, in order to meet the construction requirements, surfactants must be added to reduce the surface tension of water-based coatings; Effects of bubbles:

Because the introduction of surfactants will cause foam, resulting in defects such as pinholes, craters, and shrinkage holes on the surface of the coating, defoamers need to be added to water-based industrial paints; Dispersibility: The structure of the dispersant in the waterborne system will also be different from that of the solvent-based coating, because the hydration chain of the dispersant in the water-based system needs to be stretched in water, so some of the dispersants of the solvent-based coating cannot be applied to the water-based system coating; Tianjin Hepfil New Materials....

Not one. Coating additives, also known as paint excipients, are auxiliary materials for the preparation of coatings, which can improve the performance of coatings and promote the formation of coating films. There are many types, including driers, toughening agents, emulsifiers, thickeners, pigment dispersants, defoamers, leveling agents, anti-crusting agents, matting agents, light stabilizers, antifungal agents, antistatic agents (see plastic additives), etc., among which the largest amounts are driers and toughening agents.

At present, the research of coating additives focuses on additives for water emulsion paints. Coating additives are indispensable components of coatings, which can improve the production process, maintain stable storage, improve construction conditions, improve product quality, and endow special functions. Reasonable and correct selection of additives can reduce costs and improve economic benefits.

Paint thinners are also called "thinners". A volatile organic liquid used to dilute paints. It reduces the viscosity of the paint and makes it suitable for application methods such as brushing, spraying or dipping.

The thinners of general paints include turpentine, rosin, toluene, xylene, etc.; Toluene is often used as a diluent for spray painting, but it is sometimes referred to as a mixture of solvents (such as esters and ketones) and diluents (toluene) (i.e., "banana water").

No, the general coating additives are the added components of the coating, and the thinner is used to adjust the viscosity of the paint during the construction of the coating, so the strict sense of the additives is more like the raw material components of the coating, and the thinner is an auxiliary reagent. However, the addition of thinner can not be confused according to the different coatings, and the specific details can refer to Hangzhou Yasheng Paint.

When buying paint, paint thinner will be purchased as a supporting material, but many people don't know what paint thinner is and what it does. Today we will learn about the role of paint thinner in paint coating.

Oil celery paint thinner is a liquid substance with good miscibility with resin added in order to reduce the viscosity of resin and improve its process performance. Paint thinners are divided into reactive thinners and inactive thinners.

The thermosetting resin in the paint coating needs to add diluents to reduce its viscosity and facilitate further processing, and these diluents are actually organic solvents that are cheaper than resins, so they also play a role in reducing processing costs.

In simple terms, paint thinners can reduce the viscosity or consistency of paint to improve its process performance. Thinners can meet people's requirements, while also reducing processing costs and gaining access to a larger market.

Different types of paints use different thinners, and gasoline is usually used as a paint thinner. For example, nitro paint thinner can be used for nitro varnish, magnetic paint, and primer dilution; Nitro paint thinner can be used as a diluent for nitro paint and primer with low requirements, or used to wash nitro paint construction tools and supplies; Acrylic paint thinner, the thinner is mainly used to dilute various acrylic paints, and can also be used to dilute nitro paints.

Answer] :d solvent-based coating is made of resin, organic solvents, pigments, and fillers. The solvent is volatile and harmful, flammable, and the paint film is tough, water-resistant, and weather-resistant.
