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

Product properties:

  • isocyanate component (component B) – raw material for the production of polyurethane elastomers and low-hardness gels,
  • water resistance – gives products hydrophobic properties and ensures dimensional stability in high humidity conditions, effectively limiting water absorption in the finished polyurethane product,
  • standard viscosity – allows for easy and even distribution of the adhesive on the surface,
  • compatibility – the product is fully miscible with various polyol components and additives used in the production of polyurethane elements,
  • mechanical properties of the finished product – ensures flexible and stable mechanical parameters and excellent adhesion of the coating to various substrates, such as polyurethane foams or plastics,
  • does not contain organic solvents or plasticizers – the product is safe for the environment and chemically sensitive materials (e.g., polystyrene foam); does not contain substances that could migrate to the surface of the finished polyurethane product over time.

Product application:

  • raw material for the production of polyurethane elastomers and gels, exhibiting increased resistance to high humidity due to its ability to impart hydrophobic properties to finished products.
  • comfort-enhancing elements – cushions, gel backrests, pads, shock-absorbing elements (e.g. for sports shoes).
  • construction applications – moisture-proof coatings and seals.
