Summary
The Institute of General and Inorganic Chemistry offers consumers environmentally friendly sealing materials from anionic bitumen emulsions on the basis of a production agreement, is looking for partners to conclude a distribution service agreement or a joint venture agreement.
Description
Waterproofing materials based on aqueous bitumen dispersions meet modern environmental safety requirements. Compared with traditional solvent-borne materials, they have a number of valuable advantages, the main one of which is the absence of volatile organic solvents, which provides more favorable working conditions, reduces the requirements for fire and explosion hazards in premises. Modification of anionic bitumen emulsions with various aqueous dispersions of polymers, special additives of polyfunctional action allows the development of formulations of highly effective waterproofing compositions with specified performance characteristics, adapted to specific application technologies. A waterproofing system for cold airless application using catalyst reagents has been developed, which ensures the rapid formation of a protective seamless coating of any thickness and configuration.

The performance characteristics of a waterproofing coating based on anionic bitumen-latex emulsions have high water resistance, adhesion to a concrete surface over 0.51 MPa, elongation in tension over 322 %, strength 0.23 MPa, and the ability to regain its shape, as well as flexibility with negative temperatures of -25 °C and resistance to high temperatures up to + 90 °C.
Advantages and Innovations
The advantages of using bitumen emulsions in comparison with traditional waterproofing materials are:
* environmental safety due to the absence of organic solvents in their composition, which reduces toxicity and explosion hazard and provides more favorable working conditions when using them;
* energy efficiency is ensured due to the lack of pre-heating, which reduces the requirements for the fire hazard of the premises in which the work is carried out;
* high productivity of construction work due to the mechanized method of application to the protected surface 1 person in 8 hours can apply a coating to an area of ​​up to 400 m2;
* fast formation of waterproofing coating and ease of application;
* creation of reliable and durable waterproofing due to the formation of a uniform seamless coating with a thickness of 3 to 8 mm;
* does not require special preparation of the protected surface;
* applied to the surface of any geometric shape and configuration;
* for the production of bitumen emulsions, domestic raw materials and materials are used: bitumen, emulsifier, plasticizer;
* industrial production of anionic bitumen emulsions can be organized on equipment for the production of cationic bitumen emulsions for road construction.
