The amino resin
used in the material is a linear polymer, as the matrix of the composites; the resin plays the role of connecting coal particles and transferring stress.
Conventional amino resins
with light color and excellent yellowing resistance include the etherified product of urea or melamine condensates with formaldehyde.
Thermosetting polymers such as urea formaldehyde and melamine formaldehyde are the mostly widely used amino resins
(Conner, 1996; Pizzi, et al., 2001 and Updegraff, 1990).
To gain insight into the physical properties of the resins, we adopted an instrument for characterization of the dispersion state, Turbiscan, which uses a multiple light scattering method to monitor the storage stability of amino resins
as a function of turbidity.
has obtained a patent for a coating composition comprised of one or more organic resins comprising functional groups reactive toward alkoxyalkyl groups or alkylol groups; and a crosslinker composition comprising at least one functionalized crosslinker comprising an amino resin
core; and as substituents on the core: one or more olefin functional groups derived from the compounds selected from the group consisting of amino-functional olefins, hydroxyl functional olefins, aminoalkyl esters of unsaturated carboxylic acids and acrylamide-functional olefins; at least one silicon-containing group; and at least one group selected from the group consisting of alkoxyalkyl, alkylol and mixtures.
EBCI also produces specialty chemicals of downstream petrochemical such as synthetic latex resin (with annual capacity of 30,000 tons), unsaturated polyester resin (UPR) with an annual capacity of (20,000 tons an alkyd & amino resin
PT Petrowidada, a subsidiary of the Eterindo Group, also produces maleic anhydride (MA) which is used widely as feedstock for synthetic resin in unsaturated polyester resin, alkyd & amino resin
, fumaric acid and vinyl resin industries.
* Volatiles from amino resin
cure reactions, moisture-curable polyurethane crosslinking, and 2K waterborne urethane cure, especially if the reactions are rapid [see "More on Popping," JCT CoatingsTech, 3 (11), 120 (Nov./Dec.
Among them are synthetic latex resin (30,000 tons per annum), unsaturated polyester resin (20,000 tons per annum) and alkyd & amino resin
(20,000 tons per annum).

An earlier column (June 2004) discussed popping, but did not cover some important, but less common causes for such defects, such as volatiles produced by melamine-formaldehyde and other amino resin
crosslinking reactions, C[O.sub.2] produced by moisture-cure urethanes and 2K waterborne urethanes, and popping/gassing in powder coatings.
In May, members of the Society attended a technical meeting on "Catalysis of Amino Resin
Crosslinked and Isocyanate Crosslinked Reactions." During the presentation, John Florio, of King Industries, reviewed the primary components of acid catalyzed coatings, including the amino resin
, vehicle resin, acid catalyst, and heat.
