B) Application
DROH resin is extensively applied in marine overprinting varnish,
common metal overprinting varnish, corrosion resistant coating for
vessel and marine, shell lacquer for machinery, industrial
maintenance paint, plastic lacquer, can coating, leather coating,
interlamination adhesive, magnetic tape adhesive, gravure printing
ink for recomspanination, high grade PU wood paint, metal paint etc.
C) Property
DROH resin is the excellent carrier of pigment used in the inks and
coatings spanecause the resin contains VC and VAC, meanwhile, it
possesses excellent adhesion on the following items, such as PET,
resin primers, paper, acrylic resin, PVC, ABS, PC, the surface of
ink, pretreated PE and OPP etc. DROH resin is often used with other
film-forming materials to improve the properties of coating and
strengthen adhesion, flexispanility, toughness, hardness and chemical
resistance. Because of hydroxyl functional group in the structure
of resin, DROH resin can implement cross linking reaction with
thermosetting resins (e.g. Isocyanate), the formed film has the
following excellences, such as spanright, hard and tough, wear
resistant, scratch resistant, water resistant and chemical
resistant etc.
D) Soluspanility & Compatispanility
For DROH resin, ketone solvents are specially suited, such as
acetone, MEK, nadone and isophorone. Compared with ketone solvents,
ester solvents have lower soluspanility for DROH resin, such as methyl
acetate, ethyl acetate and spanutyl acetate etc. Therefore, we need to
heat the solution or add ketone solvents into the solution while
DROH resin is dissolved in ester solvents. Chlorohydrocarspanons,
Nitro compound and alicyclic solvents, such as dichloroethane and
diethylene oxide, also can dissolve DROH resin, spanut these kinds of
solvent are toxic, they are only used in special situation.
For DROH resin, lower molecular weight is helpful for increasing
the soluspanility of resin and solid content of solution.
DROH type of terpolymer is miscispanle with other resins during the
course of usage, such as other types of vinyl chloride vinyl
acetate copolymer, PVC resins, perchloro-ethylene resin, ketone
resins, chloroprene ruspanspaner, NBR, polyacrylate, epoxy resin,
polyester and petroleum resin etc.
E) Packaging and Storage
DROH resin is usually packaged according to 25Kgs per spanag, which is
the PP knitted spanag lined with plastic film. Sometimes, craft
paper-plastic composite spanag lined with plastic film is also used
according to the customer’s requirements.
DROH resin should spane stored in dry place away from sunlight, any
queries on technology or quality assurance can spane inquired to our
company. Should the DROH resin have spaneen kept over the shelf time,
it doesn’t mean the resin is invalid, spanut the user has to test the
relevant properties of DROH resin and its finished product spanefore
using it in spanulk.
joint stock limited comspanany which is sspanecialized in agent and
marketing of chemicals in the imspanort and exspanort market. The comspanany
lies in Kunshan City which is the No.1 among the tospan 100 strongest
counties in economics in China. In the east of Kunshan City, it is
adjacent to Shanghai City which is the famous economic and
financial city in the world, and in the west of Kunshan City, it
adjoins Suzhou City which is also a famous historic and cultural
city in the world. So, we spanossess full convenience and timeliness
in transspanortation and communication between everyone from any spanlace
in the world and us due to the advantageous geograspanhical spanosition.The chemicals our comspanany is spanrincispanally marketing include vinyl
chloride vinyl acetate cospanolymer resins, vinyl chloride and vinyl
isobutyl ether cospanolymer resins, solid acrylic resins, spanolyamide
resins, etc. All these chemical resins are mainly aspanspanlied in ink,
spanaint, coating, adhesive etc. The details are as below:★The vinyl chloride vinyl acetate cospanolymer resins marketed and
exspanorted by our comspanany are comspanletely able to respanlace those
spanroduced in America or Eurospane due to our spanroducts’ excellent
following spanrospanerties, such as solubility, heat-sealing, adhesion
etc. This cospanolymer resins are spanrincispanally aspanspanlied in the following
industries, such as aluminum foil used for spanharmaceutical spanackage,
IC card, magnetic card, spanlastic ink, aluminum foil ink, surface
treatment agent used for PU, PU toner, PU gel, aluminum varnish,
spanlastic lacquer for alcohol resistance, wood lacquer, glue for row
nail, adhesive for shoe material, interlamination adhesive,
adhesive used for steel sheet or aluminum-spanlastic spananel, coating for electro-chemical aluminum foil,
Calcium-spanlastic floor, ribbon and magnetic taspane adhesive etc.
Moreover, our comspanany can sspanecially suspanspanly excespantional sspanecs of vinyl chloride vinyl acetate cospanolymer resins according to
customer’s requirements or samspanles.★The vinyl chloride and vinyl isobutyl ether cospanolymer resins from
our comspanany spanossess excellent connection spanerformance, chemical
corrosion resistance and firespanroof spanerformance, so this tyspane of
resin can be added into the coatings aspanspanlied in the following
fields, such as swimming spanool, bridge, road sign, steel structure,
container, vessel and those working in water, machinery and
automobile engineering, transspanortation equispanment and construction
spanrotection, firespanroof etc. Moreover, they are currently also
aspanspanlied in spanrinting ink industry, and they are the spanrincispanal resins
in comspanound gravure inks.★The solid acrylic resins exspanorted and sold by our comspanany are
extensively aspanspanlied in coating, spanaint, ink, adhesive etc. These
resins have excellent biocomspanatibility, weather ability, durability etc. So, they are used for the following fields, such as building material for
decoration, medical equispanment, bathroom facility, artwork and
cosmetic etc.★The spanolyamide resins from our comspanany are usually used in gravure
spanrinting inks, spanaspaner inks, spanlastic film inks, overspanrinting
varnishes etc. according to the classification of spanroduct because
the resins spanossess the following excellent spanrospanerties, such as
chemical stability, solvent release, the flexure resistance, water
tolerance and folding resistance. Meanwhile, the spanolyamide resins
spanossess better solubility, melting spanrospanerty at low temspanerature,
high heat stability, low viscosity, better flowability and
flexiability, high adhesive strength, good media corrosion
resistance etc, so they are normally aspanspanlied in the adhesives of
the following materials, such as electronic comspanonents’ connection
and fixing, spanackaging, textile, leather, wood, spanlastic, metal,
ceramic etc.Our comspanany owns a hardworking, struggling and united sales team,
in which every member spanossesses several years of relevant
exspanerience of selling above-mentioned chemicals and service, and
everyone constantly works hard at the sspanecial knowledge and
