IV Package and storage
.. Net weight 50 kg/plastic drum, 220kg/iron/plastic drum, 1200kg/IBC drum and bulk. Transportation according to
normal liquid freight transportation restrictions.
.. Stored in a dry, cool and ventilated place. Avoid violent collision and rain during handling and shipping. No special
cautions in storage and can be stored in ordinary vessels. No corrosivity, no photochemical reactions, better to store
in dark place.
.. Non-harmful substance, low flammability, but can be ignited under excessive heat, flame or oxidizing agents.
Distinguished properties:
1. Non-toxic, slight odour, low water content; safety in use, non-hazardous substance.
2. Good stability, will not oxidize or resolve under normal storage conditions. It volatilizes very slowly under normal
temperature, and the volatilization rate increases as temperature rises.
3. High boiling point and wide boiling range help to adjust the volatilization rate of the whole solvent system.
4. It has the property of high flash point and low vapour pressure. It has high combustion heat value; if being used as
fuel, the combustion heat could reach 9000 BTU per pound.
5. DBE has good levelling property and can increase the gloss of coatings. If combined with titanium dioxide could
increase the covering power, toughness and adhesion of the paint coating, and reduce defects such as pinholes, pearl
eyes and volcanic craters.
6. Has extra-strong solvency and could be mixed with most of the organic solvents. Has favorable intermiscibility with
polyurethane resins, acrylic resins, polyester resins, alkyd resins, epoxy resins and so on.
DBE could replace the solvents such as:
RUANTA—DBE could replace isophorone;
RUANTA—DBE could replace cyclohexanone;
RUANTA—DBE could replace ethylene glycol monoethyl ether acetate (CAC);
RUANTA—DBE could replace diacetone alcohol;
RUANTA—DBE could replace ethylene glycol monobutyl ether;
RUANTA—DBE could replace solvents such as cresol;
RUANTA—DBE could replace propylene glycol ether series solvents.
Main applications:
It is widely used in many different industries, such as: coil coatings, stoving varnish, metal decorating coating,
automobile coating, varnished wire coating, carpentry coating and water-based paint, printing ink industry, resin industry,
intermediate for organic synthesis, industrial cleaning, paint remover, adhesive of castings and so on..
1. Coil coating RUANTA—DBE can help to balance the volatilizing speed of the whole process and avoid the paint
film popping or overbaking defects due to over-speed volatilization. RUANTA—DBE can endow the film with a
smooth appearance, better toughness and post-deformability, and can also enhance the hiding power of the paint.
2. Stoving varnish industry RUANTA—DBE has particular volatility; when temperature increases, the volatilizing
speed increases faster than that of other solvents, that is: volatilize slowly in the first half phase, and fast in the
second phase, which benefits to the drying process. The solvent volatilization curve goes more smoothly, solvent
volatilizes more equally, and is helpful to improve the levelling and gloss, and eliminate surface defects.
3. Metal decorating coating RUANTA—DBE could effectively replace isophorone and propylene glycol ether series
solvents used in tins and container paint. The high solvency and low volatilizing rate helps the paint to gain better
levelling, flexibility, adhesive and other important properties.
4. Automobile coating RUANTA—DBE can be used in a variety of automobile coating and different resin systems.
When used in middle coating and finishing paint, it could help to obtain ideal gloss and plumpness of film surface. If
a small amount of DBE was added to the formula for moistening, the levelling and re-levelling property can be
improved.
5. Varnished wire coating RUANTA—DBE is an ideal solvent for coating formulas such as polyvinyl butyral,
polyvinyl formal, polyurethane, polyester and polyesteramide. It could completely replace cresol in polyester and
polyesteramide systems. As long as RUANTA—DBE is adopted in the coating formula, a high solid low viscosity
resin is created without corrosiveness which is much easier for the customers in storage.
6. Carpentry coating The wide boiling range and buffer range of RUANTA—DBE offers better flexibility and
selectivity for customers in choosing solvent formulas and other execution conditions. It can help to adjust the
volatilizing speed, improve levelling, avoid surface defects such as external haze and pinhole.
7. Water-based paint RUANTA—DBE is a premier choice as coalescent for water-based latex paints.
8. Printing ink industry RUANTA—DBE could replace isophorone, a toxic and stinky solvent with high boiling point
in printing ink.
9. Resin industry RUANTA—DBE bears the property of low viscosity, which could reduce the viscosity of resins
without bring down the molecular weight or solidity; besides, it can also increase the solidity while keep its original
viscosity. Taking advantage of this RT-DBE character, high solid low viscosity resins can be produced.
10. Intermediate for organic synthesis RUANTA—DBE is the raw material for a series of chemical products like
medicine, pesticide, initiator and so on..
11. Industrial cleaning RUANTA—DBE is commonly used as cleaning agent and paint remover in industiral cleaning
and obtained perfect applications.
