Competitive Advantage:
The effectiveness of FUNDILIZER 622 surpasses significantly that of UV absorbers, particularly in pigmented systems. Combinations of FUNDILIZER 622 with UV absorbers. Typical examples are FUNDILIZER 783.
Guidelines for use
Thick sections* UV stabilization of HDPE, LLDPE,LDPE and PP 0.15-0.5%
Films UV stabilization of LDPE and LLDPE 0.1-1.2%
Tapes UV stabilization of HDPE and PP 0.2-0.8%
Fibers UV stabilization of PP fibers 0.1-1.0%
Guidelines for use
* The presence of a UV absorber (e.g. FUNDILIZER 326/327/328 and FUNDILIZER 531) is recommended in unpigmented or slightly pigmented articles or to improve the light fastness of certain organic pigments
