What is tinuvin used for?

Tinuvin® for Plastics. BASF’s light stabilizers Tinuvin® protect plastics parts against all sorts of weather conditions that lead to loss of mechanical properties and discoloration of surfaces.

What is tinuvin P?

Product Description Tinuvin P is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, imparting good light stability to a wide variety of polymers. Key Features & Benefits. – Strong absorption of UV radiation in the 300 – 400 nm range.

What Tinuvin 292?

Tinuvin 292 is a liquid hindered amine light stabilizer especially developed for coatings. It significantly extends the life of coatings by minimizing paint and varnish defects, such as yellowing, cracking and loss of gloss.

How does UV absorber work?

UV absorbers, work by targeting the incident radiation before it prevents any initial degradation. The absorb the highly energetic UV light and re-emit it at a lower energy state thereby dissipating the energy in a less dangerous form. The most important class of UV absorbers are the hydroxybenzophenones.

How can you prevent UV degradation?

There are several ways of avoiding UV degradation in plastics — by using stabilizers, absorbers or blockers. For many outdoor applications, the simple addition of carbon black at around a 2% level will provide the protection for the structure by the blocking process.

What is UV stabilizers in plastic?

UV stabilizers are substances that are used to prevent a chemical process referred to as “photo degradation” which occurs when ultraviolet radiation coming from an artificial light source or the Sun collapses chemical bonds within a polymer.

Can UV pass through metal?

Metals are almost entirely unaffected by UV because of the availability of free electrons to absorb photon energy without undergoing energy transitions or bond dissociation.

Does UV light burn plastic?

When absorbed by plastics, UV energy can excite photons. This, in turn, can create free radicals. Then, before you know it, degradation occurs, as catalyst residues will often act as receptors. The fact is, lots of pure plastics simply cannot absorb UV radiation, putting your project and its components at severe risk.

What is the most UV resistant plastic?

Acrylic is among the only manufacturing materials that is inherently UV-resistant. It is a transparent plastic that suffers as little as 3% degradation over a 10-year period when used in outdoor applications. Acrylic also offers good scratch resistance, making it an excellent choice for long-term use.

Are UV stabilizers toxic?

Currently, it lists four benzotriazole UV stabilizers as Substances of Very High Concern (SVHC) due to persistent, bioaccumulative and toxic (PBT) properties (ECHA, 2018a).

Can UV pass through aluminum foil?

Aluminum (Al) is an only material having a high reflectance to the ultraviolet light in a wavelength range of 250 nm to 400 nm. A lightweight aluminum foil having high workability is suitable for the ultraviolet light reflecting material.

What is tinuvin 622 SF?
