UV Absorbers (UVA) and Light Stabilisers (HALS)
Product Overview
Chitec offer the UK market a comprehensive portfolio of UV absorbers (UVA) and hindered amine light stabilisers (HALS) for the coatings and polymer markets, through Lawrence Industries.
UV absorbers absorb ultraviolet rays efficiently and dissipate them into heat. This helps to prevent visual and mechanical degradation as a result of photo-oxidation, thereby extending the lifetime of the product and ensuring a high performance over a longer period of time. Chitec offer chemistries based upon benzotriazoles, benzophenones, triazines and more besides. Products are available for a wide range of formulation types and applications, so get in touch today to discuss your requirements.
Light stabilisers are also manufactured by Chitec and offer free radical scavenging - mopping up free radicals generated by the exposure to sunlight. This helps to prevent further deterioration of the product. These are typically called hindered amine light stabilisers, or HALS. They can be divided into three categories: monomeric, polymeric and acid-resistant (AR-HALS) types. A combination of HALS and UVA delivers a synergistic improvement in UV protection.
