Hindered amines show excellent UV protection by scavenging free radicals generated by photo degradation. When to use HALS or other light stabilizers depends on the processing requirements and demands of the end user. In some cases, combinations of light stabilizers have shown superior performance.
In general terms, stabilizers containing sterically hinderd amines, HALS are very efficient at scavenging free radicals and thus prevent these species from reacting and causing degradation of polymer chains.
ADK STAB LA-402XP and ADK STAB LA-402Si are highly efficient light stabilizers based on a synergistic HALS blend. Offered in either a PP masterbatch form or on a synthetic silica carrier, they allow easy blending with base resins. Preferred uses include, but are not limited to, filled and pigmented polyolefins, predominantly polypropylene. They provide a high level of UV protection and hence the final article resists UV degradation for extended periods of time.
ADK STAB LA-52SC is a highly effective N-methylated HALS (hindered amine light stabilizer). In PP this light stabiliser shows a high level of bloom and fogging resistance. ADK STAB LA-52SC is especially recommended for filled and pigmented polymer formulations.
ADK STAB LA-63P is an oligomeric, high molecular weight HALS (hindered amine light stabiliser) capable of protecting a variety of polymers. ADK STAB LA-63P is N-methylated and demonstrates excellent performance in many applications and especially when used in sealants and thin films.
