    Application

    NOR 152 is a high-performance reactive light stabilizer, specifically designed to address the migration-induced depletion of stabilizers and subsequent premature degradation of coating films. This migration issue is particularly pronounced in plastic coatings, and can also occur in varnishes or wet-on-wet primer coatings.

    Featuring reactive primary hydroxyl groups, NOR 152 can covalently bind to key components in various coating systems—such as melamine and isocyanate crosslinkers—anchoring itself firmly within the coating matrix and thus effectively preventing migration.

    NOR 152 boasts excellent compatibility and long-term stabilization performance in polar, highly cross-linked coating systems, where conventional hindered amine light stabilizers (HALS) often exhibit poor compatibility. Applicable systems include:

    Polyester / Acrylic Urethane Coatings Highly Cross-linked Polyester Melamine Acrylic Melamine Systems Acid-catalyzed Automotive Coatings Coil Coatings Thermoplastic Acrylics Oxidative Drying Alkyd Resins
    ⭐ Recommended Dosage (based on resin solid content):
    Coating systems: 1% to 2% of resin solids.
    For varnishes or colored coatings susceptible to fading or discoloration, or for use on photosensitive substrates, compound NOR 152 with 1% to 3% UV absorbers for synergistic stabilization effects.

    The solid form of NOR 152 can be directly added to the polyhydroxyl component of two-component polyurethane resins or incorporated into one-component coating systems, with thorough mixing required prior to application. Alternatively, it can be pre-dissolved in a suitable solvent before being blended into the coating formulation.

    Frequently Asked Questions (FAQ)
    Q
    What is NOR 152 and what problem does it solve?
    NOR 152 is a high-performance reactive light stabilizer designed to prevent the migration-induced depletion of stabilizers in coating films. This migration issue is especially common in plastic coatings and can also affect varnishes or wet-on-wet primer coatings, leading to premature film degradation. By covalently bonding to the coating matrix, NOR 152 effectively solves this problem.
    Q
    How does NOR 152 prevent stabilizer migration?
    NOR 152 features reactive primary hydroxyl groups that enable it to covalently bind to key crosslinkers in the coating system—such as melamine and isocyanate crosslinkers. This covalent bonding anchors NOR 152 firmly within the coating matrix, preventing it from migrating out and ensuring long-term stabilization performance.
    Q
    Which coating systems is NOR 152 compatible with?
    NOR 152 is compatible with a wide range of coating systems, including polyester or acrylic urethane coatings, highly cross-linked polyester or acrylic melamine systems, traditional acid-catalyzed automotive and coil coatings, thermoplastic acrylics, and oxidative drying alkyd resins used in industrial and decorative paints and varnishes. It performs particularly well in polar, highly cross-linked systems where conventional HALS show poor compatibility.
    Q
    What is the recommended dosage of NOR 152 in coating formulations?
    The recommended dosage of NOR 152 for coating systems is 1% to 2% of resin solids. The optimal dosage should be determined based on actual application test results. For varnishes or colored coatings prone to fading or discoloration, or when applied over photosensitive substrates, it is recommended to compound NOR 152 with 1% to 3% UV absorbers to achieve synergistic stabilization effects.
    Q
    How should NOR 152 be incorporated into a coating formulation?
    NOR 152 in solid form can be directly added to the polyhydroxyl component of two-component polyurethane resins, or incorporated into one-component coating systems with thorough mixing prior to application. Alternatively, it can be pre-dissolved in a suitable solvent before being blended into the coating formulation, offering flexibility in processing.
    Q
    What is the CAS number and physical appearance of NOR 152?
    NOR 152 has a CAS number of 191743-75-6. Its physical appearance is an off-white powder. It is packaged in 25 KG drums for convenient handling and storage.
