Service Case | Extend the pot life of waterborne polyurethane by replacing the toxic isocyanate curing agent
The main material used by a customer in the post-processing stage of the product is two-component waterborne polyurethane, and isocyanate is used as the curing agent. However, during the specific production process, the customer found that if the formulated water-based polyurethane is not used up in time, the gel will deteriorate the next day and […]
Service case | replace the toxic curing agent in fabric printing industry with eco-friendly crosslinking agent
A clothing customer’s orders are mainly from the European Union. The EU has been strict in chemical control. Many batches of clothing exported by the customer were found containing chemical substances banned by the EU. The loss of direct goods and the sharp decline in subsequent orders have caused huge losses to the customer. After inspection […]

What is polycarbodiimide crosslinking agent?
What is polycarbodiimide crosslinking agent? 1. polycarbodiimide crosslinking agent Polycarbodiimide is a new type of crosslinking agent in the coating industry. Because it can be emulsified in water by introducing hydrophilic groups, it can be used for crosslinking of water-dispersed coating agents. When polycarbodiimide crosslinking agent is used, the coating agent is required to have […]
Application of carbodiimide
Overview of carbodiimide Polyurethane materials have a wide range of uses. Polyurethane elastomer is an important part of polyurethane materials. The products obtained by the reaction of polyester polyols and isocyanates have been recognized by the market for their excellent impact resistance and abrasion resistance. application of carbodiimide Carbodiimide’s application include polyurethane thermoplastic elastomers, polyurethane microporous […]
What is carbodiimide?
Carbodiimide, contains N=C=N functional groups, and is a commonly used dehydrating agent. It is generally prepared by thiourea losing hydrogen sulfide or urea losing water, and hydrolyzed to obtain urea derivatives. Mainly used to activate carboxyl groups to promote the formation of amides and esters. Basic Information of carbodiimide English name: Carbodiimide Alias: 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride […]
What are biological degradable polymer materials?
Concept and degradation mechanism of biological degradable polymer materials The biodegradable polymer material refers to a polymer material that degrades under the action of the microbes or their secretions under certain times and certain conditions. The mechanism of biodegradability roughly the following three ways: It is generally believed that biodegradable polymer materials are carried out through […]
How to extend the degradation cycle of polylactic acid (PLA) 3D printing materials
3D printing is also known as additive manufacturing. Compared with the large-scale production of traditional manufacturing, 3D printing meets the needs of many customized products. Although the cost of the product is higher, the marginal benefit also increases. 3D printing materials are an important material foundation and key material for the development of 3D printing […]
How to improve the service life of polylactic acid (PLA)
Polylatic acid, or PLA, is also referred to as polypropylene. PLA is a thermoplastic polymer obtained by polymerizing lactic acid as a main raw material. It has good biocompatibility, which can be completely degraded by natural microorganisms, and is an ideal green molecular material. Polylactic acid molecular structure PLA is a polymer material having good biocompatibility, high biological decomposition […]
