8127A SERIES™

Also known as TDI, MDI, or diisocyanate. Isocyanate is used as a hardening or curing agent in polyurethane foams, industrial coatings, elastomers, inks, and resins. It is extremely sensitive to moisture in the air and hydrocarbons making air-tight seal options extremely critical.

Alcohols having many hydroxyl radicals are called polyols. Many companies market polyols under their own trade names. Product viscosity varies greatly depending on the specific polyol, but can be as thick as 40,000 cP. Polyols are often blended with isocyanates, so pumps handing polyols are often requested to be built using isocyanate compatible lubricants.

Resins are high viscosity liquids with potentially shear sensitive (thinning) components, and made up of solvents, waxes, surfactants, and semi-solid resin particles all with various chemical compatibility concerns. These resins can be used in polyurethanes, epoxies and other adhesives. In some cases, resins contain pigments that bring with them abrasive wear concerns.

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. 

Sodium hydroxide is soluble in water, alcohol and glycerol. It is used in the manufacture of other chemicals, rayon and film, petroleum refining, pulp and paper, making of aluminum, refining vegetable oil, in detergents, soaps, textile processing, in reclaiming rubber and as an alkali in foods. The viscosity ranges from water-thin to 40 cP depending on concentration and temperature.
