DELTA-FC®1521 is a silicon-free defoamer that is effective in a wide range of water-based systems especially those based on styrene-butadiene, polyvinyl acetate, acrylic and water-soluble alkyds (mat to semi-glossy).
DELTA-FC®1521 is suited for coatings and printing inks.
Composition :Mixture of mineral oils and hydrophobic components, silicone-free

Applications and usage:
DELTA-FC®1521 is a silicone-free wide spectrum defoamer based on complex hydrocarbons.
DELTA-FC®1521 causes no discoloration and may be used in formaldehyde sensitive systems.
DELTA-FC®1521 controls the foaming tendency of surfactants in water-based coating and ink formulations (mill-base and let-down) especially those based on styrene-butadiene, polyvinyl acetate, acrylic and water-soluble alkyds.
DELTA-FC®1521 can be also effective in other applications such as the ceramic and paper industries and rubber/latex formulations.
Due to its high incompatibility, which makes it strong in defoaming, the influence of DELTA-FC®1521 upon the transparency of clear or non-pigmented systems must be evaluated.
It can be added at any stage of manufacture. For effective foam destabilization, it is advisable though to add a part of the dosage of DELTA-FC®1521 prior to processing and a part during the let-down stage.

Safety and Handling:
DELTA-FC®1521 should be handled in accordance with good industrial practice. Detailed information can be found in the Safety Data Sheet.
DELTA-FC®1521 should be stored in a cool dry place. When kept in an original unopened container, it will keep up to 1 year from the date of manufacture. The production date is indicated on the container. Stir well before use as a slight sedimentation may occur after long storage time but this does not have any influence on the product performance.
50 kg and 180 kg non-returnable plastic containers.
