In water-borne coatings, an aqueous polymer dispersion creates a film on the substrate once the solvent has evaporated. Surface functionalization of the polymer particles is a key component of a coating formulation allowing control over such properties as dispersion, film formation temperature, and the coating rheology. Dispersing aids often involve steric or electrostatic repulsion of the polymer particles, providing colloidal stability. The dispersing aids adsorb (as in a grafting onto scheme) onto latex particles giving them functionality. The association of other additives, such as thickeners shown in the schematic to the right, with adsorbed polymer material give rise to complex rheological behavior and excellent control over a coating's flow properties. Prices of such coatings are also affordable at our stop.

Silicones are polymers that include any inert, synthetic compound made up of repeating units of Siloxane which is a chain of alternating Silicon atoms and Oxygen atoms, frequently combined with carbon and/ or Hydrogen. They are typically heat- resistant and rubber- like, and are used in sealants, adhesives, lubricants, medicines, cooking utensils and thermal & electrical insulation. Some common forms include Silicone oil, Silicon grease, Silicon rubber, Silicon resin and Silicon caulk. Silicon coating is used to preserve and protect a multitude of different materials including masonry, ceramics, metals, plastics and wood. This product class is available in many different viscosities and cure speeds to suit the needs of most any coating operation. If you do not see what you need, we can modify or develop a coating to your specifications.
