Excellent product quality is our pursuit. We get customers’ trust by quality reliability.

Intimate Cooperation with customers is our strategy.New products and solutions are carried out by cooperating with customers on projects.

Product Description:

MULTIMOD™ is a series of polyester-based modified products. We use a variety of modification methods to improve the product performance to meet customer needs.

MULTIMOD has the following three series: LM series low molecular weight polyester, APT series polyester-based adhesion promoter and SMP series high-performance special modified polyester.


LM series low molecular weight polyester

It contains a series of low molecular weight polyester with specially designed structures. Low molecular weight and plenty of cross-linking groups make it be wide used in coatings, inks and adhesives to promote adhesion. At the same time, as LM series products are all solid with good solubility, its application range is further expended.

APT series adhesion promoters

It contains a series of polyester-based adhesion promoters. It can improve the adhesion to substrates or coatings of many coating, ink and adhesive systems.

SMP series high-performance modified polyester

It contains a series of special modified resins based on the molecular skeleton of polyester structure. We fully integrate the performance advantages of both polyester and other resins by grafting, hybridization and other modification methods. We can also provide customized development service to meet customer’s different demand.
