Description
RIBERG SR A (Component A) is a mixture of polyether polyols containing a catalyst and functional additives.
RIBERG SR B (Component B) is used together with Component A in a 2-component system to obtain polyurethane foam.
All work using the system must be carried out by specially trained, qualified personnel using properly functioning specialized equipment.
For professional use only
Designed for the production of rigid polyurethane foam by pouring with high-pressure machines. Recommended for the manufacture of polyurethane foam shells for the insulation of high-temperature pipelines.

Application Recommendations
To ensure optimal reaction capability and viscosity of the components before processing, it is necessary to bring the temperature of the components to the level of 20-25 °C.
Reaction parameters and free foaming density may vary depending on the intensity of mixing and the temperature of the components.
Packaging and Storage
The transportation and storage of system components must be carried out in accordance with current regulatory requirements. The transportation of system components is only done with closed transport. Transportation and storage of system components should be done at temperatures not below +15°C (for component “1”), not below +20°C (for component “2”), and not exceeding +30°C. Protect from freezing, direct sunlight exposure. The system components are highly hygroscopic!
Protect from contact with moisture and natural air humidity! It is PROHIBITED to store opened packaging with remnants of system components for subsequent use!
The shelf life of system components: 12 months for component “B” and 12 months for component “A” (provided stored in a dry, heated room in the original sealed packaging) from the date of manufacture. After the specified shelf life, system components must be checked for compliance with technical specifications, and if their suitability is confirmed, they can be used for their intended purpose.
