Description
RIBERG SG 50 (Component A) is a mixture of polyether polyols containing a catalyst and functional additives.
RIBERG B (Component B) is used in conjunction with Component A as part of a 2-component system to obtain polyurethane foam.
All work using the system must be carried out by specially trained qualified personnel using proper specialized equipment.
For professional use only.
Designed for the production of rigid polyurethane foam by pouring with the use of high-pressure machines.

Application Recommendations
To ensure optimal reaction capability and viscosity of the components before processing, it is necessary to raise 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. The recommended temperature for the mold is 30-40 °C.
Packaging and Storage
Transportation and storage of system components must comply with current regulatory requirements. The transportation of system components is carried out only with closed transport. Transportation and storage of system components should be carried out at temperatures not lower than +15 °C (for Component “1”), not lower than +20 °C (for Component “2”), and not exceeding +30 °C. Guard against freezing, direct sunlight exposure. The system components are highly hygroscopic! Guard against contact with moisture and natural air humidity! It is STRICTLY FORBIDDEN to store opened packaging with remaining system components for subsequent use! The warranty shelf life of system components is 6 months for Component “B” and 6 months for Component “A” (provided they are stored in a dry, heated room in a tightly closed original package) from the date of manufacture. After the specified shelf life, system components should be checked for compliance with technical specifications, and if their suitability is confirmed, they can be used for their intended purpose.
