Abstract

New fully saturated, long chain, linear primary alcohols are disclosed. Previously available up to molecular weight values (Mn) of approximately 700 daltons, the new products extend the range to approximately 2000 daltons. The new products are produced via controlled polymerization to yield products with consistent alcohol functionality of about 80% through the entire molecular weight range with a relatively narrow polydispersity of approximately 1.10. The products have a low viscosity while molten, and form highly crystalline, hard solid particles. The products can be micronized to particles as small as six microns.

Long Chain Primary Alcohols for Coatings, Toners, Inks, Textiles, Encapsulants, and Chemical Intermediate Applications

New fully saturated, long chain, linear primary alcohols are disclosed.  Previously available up to molecular weight values (Mn) of approximately 700 daltons, the new products extend the range to approximately 2000 daltons.  The new products are produced via controlled polymerization to yield products with consistent alcohol functionality of about 80% through the entire molecular weight range with a relatively narrow polydispersity of approximately 1.10.  The products have a low viscosity while molten, and form highly crystalline, hard solid particles.  The products can be micronized to particles as small as six microns.

The new products have the following application benefits:

·                As pigment dispersants for organic or inorganic pigments.  The new alcohols can be used to improve the dispersion of pigments into coatings.  The primary alcohol functionality combined with low viscosity from the linear structure helps wet the pigments and enable better color development and improved loading. The new alcohols can be used at levels up to 35% by weight on the pigment.

·                As dispersants for inorganic particles such as silica or talc.  The new alcohols can be used to improve the dispersion of inorganic particles into coatings.  The primary alcohol functionality combined with low viscosity from the linear structure helps wet the inorganic particles and enable better stability and improved loading. The new alcohols can be used at levels up to 10% by weight on the pigment.

·                As additives to modify the surface characteristics of the architectural paints.  The new alcohols can be used as additives to modify the appearance of the surface to a matte finish.  The new wax alcohols can also modify the coefficient of friction (also known as “slip”) of the finished paint.  The new alcohols can also improve the water resistance of the finished paint.  The new wax alcohols can be used at levels up to 5% by weight in the coating formulation, and can be added as pastilles or prills to the milling stage, or as micronized particles in the letdown stage.

·                As additives for powder coatings.  The low viscosity of the new alcohols can be used to improve the melt flow of the powder coating during the curing process.   After curing, the new alcohols can alter the surface appearance by migrating to the surface to provide a matte finish.  The primary alcohol functionality can improve the stability with pigments, resins, and other powder coating ingredients.  The new alcohols can be used at levels up to 5% by weight in the coating formulation.

·                As pigment dispersants for organic or inorganic pigments.  The new alcohols can be used to improve the dispersion of pigments into toners.  The primary alcohol functionality helps wet the pigments and enable better color development and the low viscosity helps allow improved loading.
