The current requirements of paint manufacturers in
choosingmineral fillers really need tobe taken into ac-
count by their suppliers, so that they can improve their
products and even come upwith innovations tomeet
their customer needs. “Without a doubt, key require-
ments includehighpurity,which shouldbe inexcessof

othermaterials,particularlyabrasiveones,being freeof
contaminantsand/orabrasivematerialsthatrapidlywear
out process equipment, leading to high maintenance
costs, a degree of fineness for the finished product to
avoidgrinding (simply by dispersion), and the ability of

While suppliers of mineral fillers keep developing their
products with a view to meeting all customer needs
and requirements, thecurrenteconomiccrisishasbeen

However, thedifficulties imposedby theeconomicenvi-

BIOCIDES - PROTECTION FROMPACKAGINGTODRY
FILM
New developments remain in high demand when it
comes to biocides, notwithstanding the critical situation in
which Brazil’s economy finds itself today. Among themain
requirements of paint manufacturers in choosing a biocide,
efficiency comes in first, followed by lower toxicity, to the
extent possible, and low odor, according to Karina Zanetti,
of Miracema-Nuodex’s technical support team. “We must
alwaysmake itourbusiness to recommend toeachcustomer
a biocide that acts against themicrobiota inherent in their
product.That’s thefirst item tocheckbecause ifweuseapo-
orly sizedpreservative,wecancreatecriticalmicrobiological

is on specifying biocides that will not leave any margin of
error forcontamination tooccurbecauseonce thathappens,
studying the problem and coming upwith a solution takes
time.Microbiological testsdon’talwaysprovidequickresults,

The paint and coatings industry also needs products that
deliver greater value formoney,without impacting theenvi-
ronment,accordingtoPolystellqualityassuranceandtechnical
coordinatorCecíliaCavalcante.“Ideally,thosefactorswillhelp

Evolution in the biocide business will take place following
on two paths at the same time: finding natural assets, and
developing increasingly efficient formulations that provide
excellentprotectionwhileposing lowerriskstohealthandthe
environment, according to LuizWilsonPereira Leite, marke-
ting and international business director at Ipel. “We’requite
advanced in this regard, having replaced inour formulations
all compounds that are subject to any restrictions (despite
beingnotprohibited), suchasEPOsandsolvents.Developing

at affordable costs is another form of evolution, lowering

focusedon these topics, andwe’renow starting to reap the
rewards. We’vemanaged to successfully introduce our pro-
ducts innewapplications, impartingadditional functionalities
