Description:
Sartomer has a diverse offering of monomers and oligomers that
are based on naturally derived raw materials - oils and polyols
from plant sources, including soy beans and linseeds. The product
line is described in Table 1. Detailed technical information
can be accessed from Sartomer's website by clicking the links
in the table.
The naturally derived
products offer a wide range of performance benefits to the ink
or coating formulator. CN293, CN294E, CN2001, and CN2295 are
primarily used in ink formulations. They impart good pigment
wetting, water balance, and cure speeds to UV/EB-cured inks.
CN111US and CN160 enhance flow and pigment wetting properties
in ink formulations and are often used in coating formulations
to decrease Tg and increase flexibility.The fatty acid modification
to CN116 and CN118 improves pigment wetting and reduces shrinkage
and embrittlement in cured systems.
CD611, SR203, and
SR285 are (meth)acrylates of tetrahydrofurfuryl (THF) alcohol.
CD611 is an alkoxylated acrylate version of SR285 that reduces
irritancy. THF monomers are used to improve adhesion to a variety
of non-porous substrates. SR423 and SR506A are isobornyl (meth)acrylates
and are characterized by high Tg, low shrinkage, and low crosslinking.
SR313 grades have a low Tg and are used to impart flexibility
to formulations.
Figure 1 shows the
naturally derived carbon content for each product as calculated
from the carbon contribution of source materials.
The (meth)acrylate
monomers offer fairly high levels of naturally derived content.
CD611 is an exception as alkoxylation dilutes the base alcohol.
CN111US and CN160 are direct acrylates of epoxidized natural
oils, and thus, are especially high in naturally derived content.
The (meth)acrylate
products based on naturally derived raw materials deliver performance
enhancements to energy-curable inks and coatings. Sartomer is
committed to the development of products from natural sources
and is working on the next generation of products to fill our
customers' needs.
