Adhesives
Adhesives are a group of substances, such as cement, glue, mucilage, and paste that are capable of holding materials together by surface attachment. Adhesives are made from many different basic materials, among them dextrin, latex, silicones, liquid rubber, resin, sodium silicate, and starch.
Asphalt Emulsions
Emulsions are asphalt suspended in a mixture with water or other liquids. This is done to ease the application of the asphalt. Uses would be crack filling, coating roadways, or waterproofing. These emulsions are shear sensitive and must be handled with care.
Biofuels
Biofuels include Biodiesel and Ethanol. These are fuels made from renewable resources and typically blended with refined fuels as additives.
Caulks
Caulks can be silicone, acrylic, or latex based adhesives and sealants used in industrial and home construction. Typically high viscosity & shear sensitive.
Edible Oils
This group of oils may consist of olive, palm, soybean, canola, pumpkin seed, corn, sunflower, safflower, peanut, grape seed, sesame, and rice bran or a blend of these oils that is typically referred to as vegetable oil.
Glycerol/Glycerin
This chemical is typically produced in the same process as soaps and surfactants. It is used in a wide variety of products ranging from food and beverage to personal care and disinfectants.
Liquid Fats
Recycled animal fats and vegetable oils are used in the production of animal feeds for many reasons including the acceleration of growth rates, improved taste, providing essential fatty acids and to act as a binder for producing feed pellets. Typical products include oils derived from corn, soybeans, peanuts as well as animal fats.
Lube Oil Blending
Local blending plants take bulk petroleum or synthetic base oils and mix them together with additives to create unique oil blends for specific applications and customers.
Polyvinyl Acetate (PVAC)
Poly Vinyl Acetate, or PVAC, is a colorless, odorless, tasteless, non-toxic, transparent, thermoplastic solid. It is used in latex water paints, in hot melt and other types of adhesives, for coating and finishing fabrics, as a component of lacquers, inks and in caulking compounds and chewing gum. PVAC is insoluble in water, oils and fats, but soluble in alcohols, esters, benzene and ketones.
Rubber Cement
Rubber cement, also referred to as contact cement covers a wide range of materials; some may be emulsions sensitive to shearing; others may be flammable because of the solvent carrier; others may be water solutions, which are used in a variety of adhesive-type applications. Due to the variance in material and solvent used, the viscosity varies greatly.
