Rokopol® D4020 is a specialized reactive diol used for the production of 1K and 2K adhesives, sealants and elastomers, as well as other polyurethane materials in reaction with isocyanate. The product is in a form of a liquid containing antioxidants (without BHT), which is free of impurities, and may be opalescent. It maintains dynamic viscosity within the range 700-900 mPas at 25°C with high functionality (f~2) and hydroxyl value within the range 27-31 mgKOH/g.
Rokopol® DE4020 is a product that is characterised by low content of water and sodium and potassium ions, which has a positive effect on the stability of prepolymers produced with its participation. The product is not acidified, which extends its application options. The high molecular weight (450 g/mol) provides great freedom in designing solid polyurethane systems with different hardnesses, from flexible (Shora A) to hard (Shora D) materials. The product is widely used in the construction industry, in which it is used as an element of binders, sealants, PUR and OCF foams, as well as printing inks.
The main application advantages of Rokopol® DE4020:
option of using it in a wide range of applications,
limited content of sodium and potassium ions, and water,
high stability of prepolymers produced using Rokopol® DE4020,
option of using polyol as an additive reducing viscosity,
the polyol provides good flow of elastomer systems and rigid foam,
the product allows achieving very good physicochemical properties of the final product.
The most common applications of Rokopol® DE4020:
product used as a prepolymer for adhesives and modified MDI,
adhesives, elastomers and two-component sealants of diverse hardness and high hydrolytic resistance,
product used for the production of OCF and PUR foams,
used in the production of printing inks.
Products manufactured on the basis of Rokopol® DE4020 are characterized by excellent quality. Owing to a refined production process, this product is distinguished by very good parameters and a wide range of applications.
