Cellulose acetate butyrate (CAB) is a thermoplastic cellulose ester with a butyryl content of 30-55 % by weight. It is the most commercially important blended cellulose ester, with many attractive properties such as low viscosity, high clarity and surface gloss, improved resistance to moisture and ultraviolet (UV) light, and excellent intercoating adhesion. CAB is compatible with many resin systems, including most acrylates, polyesters, phenols, ureas, and isocyanates. However, they are generally incompatible with melamine, urea-aldehydes, and many alkynes. Both solubility and miscibility depend on the butyl-group content; Generally, solubility in many resins and solvents increases with increasing butylyl content. For example, CAB resins with high butylyl content are soluble in many mixtures of esters, ketones, glycol ethers, alcohols, and aromatic hydrocarbons. CAB is commonly used in coating formulations that require low application viscosity at relatively high solids content. When added to a coating formulation, it enhances many of the properties of the coating, such as hardness, leveling, solvent resistance, clarity and shine, while reducing dry contact time, pitting, orange streaks and blocking. Because of CAB's superior property, it has many uses in coatings, including metal and wood coatings, gravure and flexographic inks, graphic art, inkjet printing inks, nail paint topcoats, automotive varnishes and primers, and general industrial coatings. We can supply many grades of cellulose acetate butyrate, so if you need more informations, pls contact us now.

In view of the fact that the numbers of COVID-19 confirmed cases in Guangdong Province of P.R. China remain high lately, as well as according to the relevant Government Departments’ requirements on epidemic prevent and control, after careful consideration the Organizers herewith announce that CHINACOAT and SFCHINA2022, originally scheduled to be held at the China Import and Export Fair Complex (CIEFC), Guangzhou, P.R. China from 6th to 8th December 2022, will be rescheduled.  The Organizer can now inform the exhibitions are rescheduled to February 22-24, 2023(Rescheduled Exhibition Date) and is to be held at the original venue of Area A, China Import and Export Fair Complex (CIEFC), Guangzhou, P.R. China. Please take special note that the Rescheduled Exhibition Date at this moment is still subject to re-confirmation and cannot be finalized yet, due to the prevailing pandemic situation in Guangzhou. If the rescheduled exhibitions cannot be held on the rescheduled exhibition date in later time, the exhibitions will be officially cancelled. When the new show date can finally be confirmed, the Organizer will issue a revised timetable with all other related information for exhibitors to prepare for the exhibitions.

Anticorrosive coatings are generally divided into conventional anticorrosive coatings and heavy anticorrosive coatings, which are an essential coating in paint coatings. Conventional anti-corrosive coatings are used to prevent corrosion of metals and other materials under normal conditions and protect the life of non-ferrous metals. Heavy anticorrosive coating refers to a type of anticorrosive coating that can be applied in relatively severe corrosive environments and has a longer protection period than conventional anticorrosive coatings compared to conventional anticorrosive coatings. What are the categories of anticorrosive coatings？ (1) Classified by chemical composition Divided into: acrylic anticorrosive paint, polyurethane anticorrosive paint, inorganic anticorrosive paint, epoxy anticorrosive paint, perchloroethylene anticorrosive paint, high chlorinated polyethylene anticorrosive paint, chlorinated rubber anticorrosive paint. These kinds of imitation decay paints have different functions due to their different main chemical components. They are suitable for different kinds of objects. Among them, perchloroethylene anticorrosive paint is suitable for the surface of wood and construction metal. It can also prevent the corrosion of acidic and alkaline substances of chemical products. (2) Classified by solvent Divided into: water-based anti-corrosive paint and oil-based anti-corrosive paint. Water-based paint can be diluted with water, its hardness climbs slowly but it has good water resistance after drying. The biggest feature of water-based anticorrosive paint is environmental. Oily anticorrosive paints use banana water and tianna water as diluents and contain some chemicals that are not good for the human body. It contains a strong pungent odor. However, the drying time of oily paint is shorter than that of water-based anticorrosive paint. The anticorrosive effect is also very good. (3) Classification by functions It is divided into seven categories: furniture anticorrosive paint, metal anticorrosive paint, marine anticorrosive paint, automotive anticorrosive paint, steel structure anticorrosive paint and rubber anticorrosive paint. The classification of anticorrosive paints has special physical and chemical reasons. We must be careful when selecting them. Never mix different types of paints or choose paints in other fields.
