Description
RIBERG TR 40 A (Component A) is a mixture of polyether polyols containing a catalyst and functional additives and a physical foaming agent
RIBERG B (Component B) is used in conjunction with Component A in a 2-component system to obtain polyurethane foam.
All work with the system must be carried out by specially trained and qualified personnel using functional specialized equipment.
For professional use only
Designed for the production of rigid polyurethane foam by pouring with 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 pipe temperature is 20-30 °C.
Packaging and Storage
Transportation and storage of system components must comply with current regulatory requirements. 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: 6 months for component “B” and 6 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.
