What are Acrylic Resins?
Jun 14, 2022 What are Acrylic Resins?
An Acrylic resin is a polymeric material (in solution, dispersion or solid) containing acrylic monomers. These monomers are usually esters of acrylic, methacrylic acids or their derivatives, and can be functionalized by introducing different chemical groups (R groups). Others monomers can also be incorporated in the polymer chains in order to obtain resins with different properties or lower cost. In general Acrylic resins show good chemical and photochemical resistance. They are commonly used in many different applications, from solvent-based and water-based industrial coatings to architectural coatings. Selecting Acrylic Resins: Glass Transition Temperature (Tg) The Glass Transition Temperature (Tg) is the temperature at which a polymeric material will go from a glassy solid state to a liquid state. The Tg of an acrylic resin is defined by the resin formulation. This parameter has a key role on Hardness/flexibility of the final paint film. The following rules can help selecting a resin formulation with suitable Tg: Tg will strongly depend on the resin monomers (methacrylate monomers have a higher Tg than acrylate ones) Tg increases with the degree of cross-linking (number of cross-links between 2 polymer chains) Higher the Tg , harder (less flexible) the film obtained The presence of other monomers (styrene for example), the nature of the reactive or non-reactive R group present or the Tg of the crosslinking agent used (melamine or isocyanate for example) will of course influence the final Tg. Viscosity The viscosity of an acrylic resin depends on the solid content, but the average molecular weight of the polymers in the resin and the molecular weight distribution will also have an impact. Usually the following rules apply: For the same solid content the higher the average molecular weight of the polymer the higher the viscosity. When the average molecular weight is the same, narrower the molecular weight distribution, lower is the viscosity. It is important to notice that the average molecular weight has no influence on the viscosity for latex emulsions. In this specific case viscosity depends on the particle size and size distribution. Acid Value The acid is an indicator of the number of carboxyl group present on in the copolymer. It is usually expressed as the amount of KOH needed to neutralize1gof resin (See DIN 53402 or ISO 2114). The number of carboxyl group has an impact on the adhesion properties of the resin and on the solubility in water. The higher the acid value, the higher the number of carboxyl groups. Hydroxyl Value Number The hydroxyl value is an indicator of the reactivity of the acrylic resins functionalized with hydroxyl functions (ie the number of OH group available). It is usually expressed as the KOH mass in mg equivalent to the amount of acetic acid reacting during the acetylation of1gof resin. The higher the hydroxyl value, the higher the reactivity (and thus the cross-linking possibilities). Minimum Film-forming Temperat...

Holiday Notice of 2022 Dragon Boat Festival
Jun 01, 2022 Holiday Notice of 2022 Dragon Boat Festival
Along with the summer, the annual Dragon Boat Festival is coming. On this speical season, we wish everyone happiness and health, all the best, and a happy Dragon Boat Festival! The fifth day of the fifth lunar month is a traditional Chinese folk festival - the Dragon Boat Festival, which is one of the ancient traditional festivals of the Chinese nation.  Celebrating the Dragon Boat Festival has been a traditional Chinese custom for more than 2,000 years. Due to the vast territory, numerous ethnic groups, and many stories and legends, different customs in different places. Its contents mainly include: hanging calamus and wormwood, wearing sachets, preparing glutinous rice, dragon boat racing, drinking realgar wine, calamus wine, eating five poisonous cakes, salted eggs, zongzi and seasonal fresh fruits, etc. It is a significant holiday in China. It memory of a talented and patriotic poet called Qu Yuan, who drowned in Miluo River on the 5th day of the 5th lunar month in 278 B.C. To celebrate the upcoming 2022 Dragon Boat Festival, Sunman company is scheduled a 3-day holiday which is from June 3th to June 5th. We will be back to work on June 6th, 2022. Sorry for any inconvenience it may have.

Market trend of polyamide resin
May 24, 2022 Market trend of polyamide resin
Polyamide resin is the main raw material for ink production. So it effect cost of ink directly if polyamide resin is keeping rise sharply. Since last year, the price trend of polyamide resin has been on the rise. What causes polyamide resin prices to continue to rise? Let's share some informations as follows; It is well known that the main raw material of polyamide resin is oleic acid. With the development of biodiesel industry, a large number of oleic acid raw materials have poured into the biodiesel market, resulting in a shortage of oleic acid in the plant producing polyamide resin.especially this year the international oil price fluctuates, the overall trend will rise sharply, and the increase will hit a record high in seven years.  China domestic gasoline and diesel prices is keeping rise every month. So it makes there have very large demand for biodiesel in market this year. By the end of 2021, the spread of Omicron mutant virus will bring pressure to the logistics supply chain. Port congestion will continue to ferment, and freight rates will rise all the way. Supply chain congestion has become the biggest driving force for freight rate rise. By this year, the global terminal congestion situation will continue. The freight charges don't drop down. Dow and many other big factories were suddenly suspended due to force majeure from last month. So it makes prices of various chemical raw materials continued to rise, especially the price of ethylenediamine(raw material of polyamide resin) rise sharply. According to this market situation, the price of polyamide resin will continue to keep higher level in the coming months, making it difficult to reduce the cost of polyamide resin. Sunman had export polyamide resin more than 18 years with rich experience So If you need it, welcome to check with us!
