WHY USE COASOL®?

Coasol® is a specialist low VOC coalescent product, for use in indoor water-borne architectural paints, owned and trademarked by SEQENS Custom Specialties. Coalescence is defined as the process by which a uniform and compact film is obtained by the drying of organic, polymer-based latex emulsion paints.

SEQENS Custom Specialties is one of Europe’s leading experts in high purity, complex reaction-distillation, and is the only manufacturer of Coasol®, which is a coalescent additive used to promote fusion of the polymer particles to form a uniform and compact film by softening the polymer particles and allowing them to fuse together.

Coalescence and its efficacy are fundamental steps in the formulation of Latex paints, as many of their properties and performance in use are due to the coalescent used.

Coasol® combines an excellent suite of properties to produce non VOC, non-odour coatings and is classed as non VOC under European Directive 2004/42/CE.

Applications

Coasol® is a very high performance coalescing system which gives the formulator flexibility to achieve low VOC targets whilst improving paint performance in a number of areas.

Coasol® finds application in industrial cleaners where its eco-profile distinguishes it from other technologies. It is used in hard surface cleaners, as a component in printing paint cleaners, for removal of floor wax. Certain Graffiti removal formulations use its high degree of solvency.

Coasol® is used with unsaturated polyester resins or epoxy resin systems, and can be used as a low tail solvent in coil coatings, or to reduce VOC in high solid formulations.

Coasol®has been used in a number of oil-field applications including low temperature fluids, wax dispersion and various rig cleaning applications.

Another similar product from SEQENS Custom Specialties that you may be interested in is Coasol® 290 plus, which is ideal if you require a non VOC low-odour coating.
