Applications of COASOL TM in coatings
COASOL TM is used as coalescing agent in water
based coatings.Characteristic criteria for the use of
COASOL TM are:
?Non VOC(V apour pressure<0.01kPa at20°C)
?Low odour
? Meets Ecolabel regulation
?Extended open time
?Hydrolytically stable
?Better scrub resistance due to more complete coales-
cence of hard polymers and less affinity to water than
other coalescence agents
?Better water resistance of the dried coating
?Lower MFFT with V A polymers
COASOL TM is used in floor lacquers,coatings for concrete
surfaces and other coatings where high perfor mance is
needed.The amount used is normally2–5%of the binder
calculated as solid.

Applicatio ns in the industrial cleaners &polymer industry
COASOL TM is used as a low toxicity solvent in a range of
industrial cleaner&polymer applications due to the following
key properties:
?Dissolves most resins
?Blends with Hydrocarbons
?Blends with T erpenes and d-limonene
?Does not contain chlorinated compounds
?High solvency power for polar and non polar soils
?Non VOC
COASO TM L is miscible with most commonly used solvents
including:
?Alcohols
?Glycol Ethers
?Esters
?T erpenes
?Hydrocarbons
?Chlorinated Solvents
?Glycol Ether Acetates
?Ketones.
COASOL TM can also be applied in emulsified products due to
the good hydrolytic stability.
