Rokanate M PE 0820 is a low-functionality MDI-based prepolymer. The product is a polyurethane adhesive in the form of a clear liquid with a viscosity of 450-1450 mPas at 25°C and an NCO content of 10.5-12.0%.

Rokanate M PE 0820 is used as component B in two-component formulations for solid, flexible polyurethane products with low hardness (in the range of Shore 00 and Shore A). In particular, Rokanate M PE 0820 is used for the production of hydrophobic gels and elastomers, highly elastic coatings and joints with low water absorption, which exhibit dimensional stability under conditions of increased humidity. Depending on the polyol component (A) used, the product allows for the production of polyurethane elements with selected mechanical properties (hardness, elasticity). Examples of applications include flexible coatings, gel cushions, seat and backrest elements, and other accessories that improve comfort, such as shock-absorbing soles for sports shoes.

Properties and applications

Properties:

  • isocyanate component (Component B) – a raw material for the production of low-hardness polyurethane elastomers and gels,
  • water resistance – imparts hydrophobic properties to products and ensures dimensional stability under high-humidity conditions, effectively limiting water absorption in the finished polyurethane product,
  • standard viscosity—allows for easy and even application of the adhesive onto the surface,
  • the product is fully miscible with various polyol components and additives used in the production of polyurethane components,
  • mechanical properties of the finished product – ensures flexible and stable mechanical parameters as well as excellent adhesion of the applied coating to a variety of substrates, such as polyurethane foams or plastics,
  • contains no organic solvents or plasticizers – the product is safe for chemically sensitive materials (e.g., expanded polystyrene); contains no substances that could migrate to the surface of the finished polyurethane product over time,
  • the product has not been classified as posing a risk to the environment under Regulation (EC) No. 1272/2008, as amended.

Application:

  • the product is used as a raw material in the production of polyurethane elastomers and gels, imparting hydrophobic properties to the finished products and increasing their resistance to moisture,
  • the product is used in the production of components that enhance user comfort, such as cushions, gel backrests, pads, and shock-absorbing elements, including those used in athletic footwear,
  • the product is used in the construction industry for the production of coatings and seals that provide protection against moisture.
