Concentrol have launched a new range of antifoaming agents based on vegetable oils: biodegradable, emission-free and very effective
Controlling the formation of foam in the coatings sector has always been a challenge, since the antifoaming agent must be effective during the manufacturing process and while offering excellent efficiency during the life of the coating, which in many cases it is long. In addition, coating formulations must currently comply with strict environmental regulations that limit, for example, the amount of volatile compounds (VOC and SVOC) that can take part in atmospheric photochemical processes and are considered to favour the formation of ozone at the surface level.
Traditionally, antifoaming agents used to control foaming in these applications are based on mineral oils whose origin is petroleum. These antifoaming agents are economical and effective, but they are virtually toxic (to a greater or lesser extent depending on the type and origin of the mineral oil used) and in many cases they contain high amounts of VOC and SVOC. Recently, the European Commission and countries such as Germany have started risk assessment processes associated with these materials, 2,3 generating the need to declare the presence of mineral oils and aromatic mineral oils (MOSH and MOAH) in many food products. For this reason, the replacement of these mineral oils with alternatives of lower toxicity, lower emissions, of a non-petroleum origin and environmentally more favourable is an increasingly important requirement.
NEW SOLUTIONS FOR FOAM CONTROL IN PAINTS
Concentrol have launched the new antifoaming agent EMULTROL DFM OLV-24, the first one of a new range of products, designed following the criteria of biodegradability, low or no toxicity and low or zero missions of volatile components (VOC and SVOC). It is based on vegetable esters that are obtained sustainably and totally free of traditional mineral oils.
Even with these changes, the careful formulation and selection of raw materials has enabled us to obtain an antifoaming agent that offers a performance equal to or in some cases superior to that obtained with traditional antifoaming agents based on mineral oils.
