The performance and lifespan of coatings are significantly influenced by their ability to withstand environmental factors, particularly ultraviolet (UV) radiation. UV exposure can cause coatings to degrade, leading to loss of gloss, chalking, cracking, and color fading, compromising both their aesthetic appeal and protective functions. For coating manufacturers seeking to deliver durable and high-performing finishes, the inclusion of effective UV absorbers is non-negotiable.

As a prominent manufacturer and supplier of specialty chemicals, we offer 2,4-Dihydroxybenzophenone (CAS 131-56-6), a benzophenone-based UV absorber that provides exceptional protection for a wide range of coating systems.

The Impact of UV Radiation on Coatings

UV radiation initiates photochemical reactions that break down the polymer binders and pigments within coatings. This degradation process can:

  • Reduce Gloss: Surface deterioration leads to a dulling effect.
  • Cause Chalking: The binder breaks down, forming a powdery residue.
  • Lead to Cracking and Delamination: Loss of flexibility and adhesion occurs.
  • Fade Colors: Pigments are chemically altered by UV light.

Why 2,4-Dihydroxybenzophenone is Essential for Coatings

Our 2,4-Dihydroxybenzophenone is a highly effective UV absorber, delivering critical benefits for coating formulations:

  • Broad UV Absorption: It efficiently absorbs UV radiation in the 280-320 nm range, protecting the coating matrix from photo-degradation.
  • Excellent Compatibility: It is soluble in many common organic solvents used in coatings and exhibits good compatibility with various resin systems, including alkyd, phenolic, epoxy, and unsaturated polyesters. This ensures ease of formulation and uniform dispersion.
  • Enhanced Weatherfastness: By mitigating UV damage, it significantly improves the resistance of coatings to weathering, extending their service life and maintaining appearance.
  • Protection for Various Resins: It is particularly beneficial for resins that are prone to UV degradation, such as alkyd and phenolic resins, as well as advanced systems like epoxy and unsaturated polyesters.
  • Direct Manufacturer Supply: As a leading supplier based in China, we provide this crucial additive at competitive prices, ensuring excellent value for manufacturers.

Applications in the Coatings Industry:

Our 2,4-Dihydroxybenzophenone is a versatile additive for numerous coating applications, including:
