    Description

    MOFAN TMR-2 is a tertiary amine catalyst used to promote polyisocyanurate reaction (trimerization reaction),Provides a uniform and controlled rise profile compared to potassium based catalysts. Used in rigid foam applications where improved flowability is required. MOFAN TMR-2 can also be used in flexible molded foam applications for back-end cure.

    Application

    MOFAN TMR-2 is used for refrigerator,freezer,polyurethane continuous panel ,pipe insulation etc.

    Handling and storage

    Advice on safe handling
    Use personal protective equipment.
    Do not eat, drink or smoke during use.
    Overheating of a quaternary amine for prolonged p eriods above 180 F (82.22 C) can cause product to degrade.
    Emergency showers and eye wash stations should be readily accessible.
    Adhere to work practice rules established by government regulations.
    Use only in well-ventilated areas.
    Avoid contact with eyes.
    Avoid breathing vapors and/or aerosols.

    Hygiene measures
    Provide readily accessible eye wash stations and safety showers.

    General protective measures
    Discard contaminated leather articles.
    Wash hands at the end of each workshift and before eating, smoking or using the toilet.

    Storage Information
    Do not store near acids.
    Keep away from alkalis.
    Keep containers tightly closed in a dry, cool and well-ventilated place.

    FAQ

    I want to produce PIR foam with extremely low friability. Is TMR-2 better than TMR-30?

    Yes, TMR-2 (a quaternary ammonium salt) gives much lower friability while still providing excellent fire performance.

    My rigid foam has poor adhesion to aluminum foil. How can TMR-2 help?

    Its polar nature improves adhesion to metal surfaces, reducing delamination.

    What is the typical usage level of TMR-2 in a continuous PIR laminate?

    0.4–1.2 phr depending on the desired trimer content and line speed.

    Can TMR-2 be used together with potassium octoate?

    Yes, they are synergistic. A blend of TMR-2 (0.5 phr) and potassium octoate (0.5 phr) gives excellent trimerization with low brittleness.

    My PIR foam has a rough, uneven cell structure. How to improve?

    Increase TMR-2 slightly and reduce the amount of strong gel catalyst to allow more controlled bubble growth.

    Is TMR-2 water-soluble? How does that affect processing?

    Yes, it is water-soluble, but keep water out of the formulation as it will react with isocyanate.

    Does TMR-2 cause corrosion on mixing heads?

    No, it is much less corrosive than alkali metal catalysts.

    My foam panel fails the room temperature aging test (dimensional change >1%). Can TMR-2 fix it?

    Yes, the higher trimer content from TMR-2 improves dimensional stability significantly.

    What is the shelf life of a polyol blend containing TMR-2?

    3–6 months, but avoid moisture pickup as TMR-2 is hygroscopic.

    Can TMR-2 be used in pour-in-place pipe insulation?

    Yes, it provides good flow and low friability, suitable for large-diameter pipes.
