Light and heat stabilizer solution for SMP sealants



The increasing focus on sustainability and the need to improve the labelling profile, while at the same time being in line with today’s market trends is challenging the silyl modified polymers (SMP) sealants industry to develop new solutions for pigmented and clear systems.

The new AddWorks® IBC 760 provides you with an additive solution addressing these challenges, all while enhancing the performance of SMP sealants. It is hazard label-free and has global registration status.

Outstanding light and heat stability

AddWorks® IBC 760 is a mixture of a UV absorber, hindered amine light stabilizer (HALS) and antioxidant without any hazard labeling and designed to provide outstanding performance in SMP sealants in terms of light and heat stabilization. Available in micronized powder form, AddWorks® IBC 760 prolongs the service life of SMP sealants as it reduces cracking and yellowing that typically occurs if exposed to strong sunlight or high temperature conditions. The performance is evident when tested against current benzotriazole containing solutions in the market. Our new stabilizer solution is an ideal ingredient to formulate high performance SMP sealants used for construction, automotive and other outdoor applications.

  • Plastics in industrial building and construction
    In the area of plastics used in industrial building and construction, Clariant has come up with a range of innovative solutions for polymer improvement. They make roofs and outdoor decks more weather-proof, window frames more aesthetic, and in some cases they can even make watching a soccer match a much more pleasurable experience. Thanks to the protection given by light stabilizers as well as a strong heat resistance resulting from the use of antioxidants or heat stabilizers, plastics for Industrial, Building and Construction using Clariant's AddWorks® IBC solutions are well protected against temperature, even high temperature during conversion or end use, or even against intense UV radiation, as well as other difficult weather conditions.
  • Architectural coatings in building and construction
    Our state-of-the-art coating solutions help to preserve and protect that well-being, providing e.g. dirt pickup resistance to prolong the proper looks of architectural coatings. Light stabilizer solutions contribute to making both the coatings and the substrates they protect more resistant to the highly exposed conditions they usually have to endure, like façade coatings based on styrene acrylic mixtures.
  • Powder coatings in building and construction
    We provide powerful additive solutions to make sure these coatings stay tough, even if the going gets rough! They are usable for a broad range of powder resins, such as polyester or polyester/epoxy binders and usable with Primid® products. The additives comprise not only light stabilizer solutions, but also antioxidants, thus preventing gas fading and thermal yellowing of powder coatings.
  • Wood coatings in building and construction
    The natural beauty of wood is something worthy of the best protection against weather conditions and other influences which might mar its shine and intense colors. We offer e.g. light stabilizer solutions that improve weathering resistance and reduce color fading and loss of gloss.
