alkyd paint price

> Alkyd paint, also known as alkyd resin paint or alkyd resin paint, is mainly composed of alkyd resin and is currently the largest type of paint produced in China. It has the advantages of low price, simple construction and low requirements on the construction environment. The coating film is plump, hard, durable and weather-resistant, and has good decorative and protective properties.
Indicates the content of weakly polar structures in alkyd resin. Because long-chain fatty acids are less polar than polyester structures, the content of weakly polar structures directly affects the solubility of alkyd resins. For example, long-oil alkyd resins have good solubility and are easily soluble in solvents such as gasoline and medium-oil alkyd resins. Soluble in solvents: gasoline, mixed solvents, short oil alkyd resins have the worst solubility, need to be dissolved with alcohol or alcohol/ester mixed solvents. At the same time, the oil level affects the gloss, brushability, leveling and other construction properties. It also has an impact, with a high content of weakly polar structures, high gloss, and good brushability and leveling properties.
Indicates the content of flexible components in alkyd resin, because long-chain fatty acid residues are flexible segments, while phthalic anhydride polyester is a rigid segment, so it also reflects the glass transition temperature of the resin or what is often called the soft segment. Hardness, the hardness is lower when the oil content is long, and the gloss and color retention is poor.
Alkyd acid resin is produced by the condensation polymerization of polyol phthalic anhydride and fatty acid or oil. for good paint.
Classification and numbering of flammable liquids in Danger Regulations, refer to, page,.
Hazardous characteristics: Flammable, flash point ~℃. There is a danger of burning when exposed to high-temperature open flame oxidants, and the pyrolysis products of the resin are toxic.
Identify the type of accident: fire poisoning container burst.
Firefighting methods Firefighters must wear gas masks and full-body protective clothing. Use foam mist water, dry powder carbon dioxide fire extinguishing agent, and sand to extinguish the fire.
In first aid, patients who have inhaled pyrolysis gas should be removed from the contaminated area, placed to rest and kept warm. Severe cases are sent to the hospital for treatment.
Storage and transportation instructions for dangerous goods.
Packaging marks flammable liquids.
Packaging method Iron drum.
Storage and transportation conditions Store in a cool and ventilated warehouse. Keep away from heat sources and fires, avoid direct sunlight, and store and transport in isolation from oxidants.
To deal with leakage, first cut off all fire sources, wear a gas mask and gloves, absorb it with sand, pour it into an open place for burial or burn it in an incinerator, scrape the contaminated ground with a putty knife, and remove large areas around leakage A mist water curtain should be installed to suppress explosions.
Refers to a new alkyd resin formed by chemical reaction in addition to fatty acid polyol phthalic anhydride or isophthalic acid, such as rosin-modified alkyd resin benzene. Ethylene-modified alkyd resin, benzoic acid-modified alkyd resin, etc. If all fatty acids are replaced by other components, it is called oil-free alkyd resin. Mainly used to prepare coatings and inks. It has the characteristics of quick drying adhesion, good weather resistance and good impact resistance. Alkyd resin can be formulated with other resins to form a variety of self-drying or drying enamel primers, topcoats and varnishes with different properties. They are widely used in the coating of bridges and other buildings as well as machinery, vehicles, ships, aircraft instruments, etc.
