NEW TECHNOLOGIES BRING‘EASE OF USE’
Dispersions: Use Our Expertise

Technology: Greater Value for You

SI Group has two centers of expertise for thepreparation and technical support ofemulsions and dispersions: Waldkraiburg,Germany and Nanjing, China. Our
technologists can help develop the best costperformance dispersion or emulsion to meetyour exact needs and enquiries to use
our expertise for the benefit of ourcustomers,
are always welcomed. An extensive range ofdispersions is available directly fromSI Group or from our global network ofpartners specialized in dispersion
technology.

A new ‘self-emulsifying’ form (‘SE’) has beendeveloped for a large number of liquid
products and blends that are used in an
aqueous environment, such as natural orsynthetic latex and the emulsion
polymerization of synthetic elastomers. TheSE products do not contain water; however,they can easily be added to water or latex.
Mild stirring immediately creates theformation of a stable emulsion. The direct
injection of the SE products into theproduction process allows productivity gains
as one handling step is removed.

Benefits of SI Group’s
Dispersion Technologies• Liquid physical form, ease of use• Improved dosage accuracy• Finely dispersed additives, whichguarantee efficiency• Customized particle size and concentration• Synergistic blends and solutions giving
tailored performance for different
applications• Long term stability• Improved HSE environment: No dust, noVOC, no explosion risk

Self-emulsifying technology

Benefits from
Self-emulsifying Technlogy• Simplified process - as direct injection ispossible• Easier handling and dosage• Lower costs - no need to ship water/
dispersions around the world• Lower costs for emulsion preparation–noneed for emulsifiers• No issues related to emulsion/dispersion
stability and storage• Improved productivity as mixing isinstantaneous and homogeneous• Easier dispersion into latex
