Product Description
Product Details
Introduction
PVDC emulsion is made by polymerization of vinylidene chloride and acrylic esters, and can be directly coated on the surface of the substrate. Because its medium is water, it is easy to use, safe and reliable. It is widely used in BOPP, BOPET, PVC sheets, disposable environmentally friendly tableware, paper packaging inner layer and other packaging in the tobacco, food and pharmaceutical industries.
Physical and chemical properties
Milky white acidic low viscosity liquid, odorless, relative density 1.2-1.32g/cm3(20℃). Its PVC composite material is characterized by high moisture resistance, high oxygen resistance, good flexibility, printable and high transparency.
Application
Suitable for primers of PVC sheets, cardboard and other substrates, petroleum coatings, etc.
