CHINACOAT2013 Preview
many performance advantages when used as the single Direct-to-Metal (DTM) coating.
This presentation will highlight the performance properties of
the waterborne DTM technology, as well as the mechanisms and
fundamentals which have been used in the resin development.
Theme 5: Polyurethane Coatings will feature a presentation, “Innovative PU Solutions for Coatings,” given by
Frank Zhang, segment head for application development
APAC, Bayer MaterialScience. Polyurethane coatings had
been widely used in varies applications. With the increasing
requirements on Environment, Efficiency & higher performance, the new requirements to conventional solventborne
polyurethane coatings had been raised as well. In this session, we will discuss how waterborne PU or WB UV to
achieve high performance as well as environment friendly
& efficiency at the same time. This is also the trends for
coatings in the future.
Theme 6: Tackifiers will offer a presentation from Won
Suk Kong of Kolon Industries. His presentation is” Synthesis
and Characterization of Hydrogenated Sorbic Acid Grafted
Dicyclopentadiene Tackifier.”
Typically, hydrocarbon resins are non-polar, and thus highly
compatible with non-polar rubbers and polymer. However, they
are poorly compatible with polar system, such as acrylic copoly-
mer, polyurethanes and polyamides. Moreover, recently the raw
materials of tackifier from naphtha cracking had been decreased
because of light feed cracking such as gas cracking. To overcome
this problem, novel hydrocarbon resins were designed to have
a highly polar chemical structure. And, it was synthesized by
Diels-Alder reaction of dicyclopentadiene monomer and sorbic
acid from blueberry as renewable resources. Acrylic resins were
formulated with various tackifiers solution including hydroge-
nated sorbic acid grafted dicyclopentadiene tackifier in acrylic
adhesive and rolling ball tack, loop tack, 180° peel adhesion
strength, and shear adhesion strength were measured. And
Rheometer, DSC (Differential Scanning Calorimetry) and XRD
(X-ray diffraction), the properties depend on the softening point
and polar content of tackifiers. CW
CHINACOAT2013 will take place Nov. 20-22 at the Shanghai New International Expo Center. There will be six exhibit zones featuring a total of 920 exhibitors
from 33 countries/regions who will showcase their goods and services.
