Find Your Polyurea Solutions

Polyurea coating / elastomer is derived from the reaction product of a polyisocyanate component and an amine-terminated resin blend

Polyurea application requires training and special equipment in order to utilize the product properly.

Polyurea can be used to coat or contain any substance from normal sanitary sewer systems, to FDA/potable water applications, as well as crude oil secondary containments.

As a general recommendation for constant exposure to direct chemical contact, POLYCO polyurea products may not be installed for:

Halogen substituted Solvents

  • Carbon tetrachloride
  • Highly substituted carbon rings
  • Methylene chloride
  • Tetrachloroethane
  • Trichlorethene

Non-Halogenated Solvents and Ketones

  • Acetone
  • Acetonitrile
  • Acetophenone
  • Benzene
  • Butanol
  • Camphor oil
  • Cyclohexanone
  • Diethyl ether
  • Diisobutyl ketone
  • Ethyl acetate
  • Hexane
  • Methyl ethyl ketone
  • Methyl isobutyl ketone 
  • Pentane
  • Phenol
  • Xylene
  • Acidic compounds with pH of 4 or lower
  • Basic compounds with pH of 11 or higher.

In the case of Non-aqueous (anhydrous and anhydride compounds in granular, crystalline, or powder form) that are protected by an air drying system may be acceptable for contact with polyurea. Consult with The Polyurea Company for clarification.

Amine Attacking And Amine Containing Compounds strong, inorganic acids, organic acid halides, aldehydes, isocyanates, organic anhydrides. Given that the backbone of polyurea is a poly amine chain, it is only natural any compounds that seek to attach this bond link will be unacceptable for containment with polyurea. Examples of these are:

  • Aminoethylethanolamine
  • Aniline
  • Ethylamine
  • Methylamine
  • Pyridine
  • Toluenediamine

Please refer to our chemical resistance chart of our aromatic polyurea for your reference

Heat of deflection under no load is +250°F, depending on system. Safe upper limit of working temperature is +350°F, under no load. Dependent on product/system.

Polyurea may be either hard or soft depending on the particular formulation and its intended use. Hardness ratings may range from Shore A 30 (very soft) to Shore D 80 (very hard)

“Aromatic Systems “ polyurea products are based on an aromatic isocyanate. They are very reliable under UV exposure, but they are not color stable. The surface’s color changes in sunlight, but it does not affect its physical properties.

“Aliphatic System” polyurea products are based on an aliphatic diisocyanate, and they are color-stable. This means that they don’t change color under light exposure (natural or artificial). They are generally more difficult to make and cost more than aromatic polyurea products.
