Description
Phenol, 2-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl-5-3-(2-ethylhexyl)oxy-2-hydroxypropoxy-, also known as Tinuvin 405, is a solid triazine-based UV absorber used in the coatings industry. It is designed to meet high performance and durability requirements, particularly for acrylic powder coatings in transportation and industrial applications. This light yellow powder is characterized by its ability to absorb ultraviolet light, providing protection against degradation and discoloration caused by exposure to sunlight.
Uses
1. Used in Automotive Clear Coats:
Phenol, 2-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl-5-3-(2-ethylhexyl)oxy-2-hydroxypropoxyis used as a UV absorber in automotive clear coats to protect the paint from fading, discoloration, and degradation caused by exposure to sunlight. This helps maintain the appearance and longevity of the vehicle's finish.
2. Used in Automotive Powder Clear Coats:
In automotive powder clear coats, Phenol, 2-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl-5-3-(2-ethylhexyl)oxy-2-hydroxypropoxyserves as a UV stabilizer, ensuring the durability and color retention of the powder coating. This is crucial for maintaining the aesthetic appeal and protecting the underlying materials from UV damage.
3. Used in Powder Coatings for Plastics and Wood:
Phenol, 2-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl-5-3-(2-ethylhexyl)oxy-2-hydroxypropoxyis utilized as a UV protectant in powder coatings for plastics and wood. This application helps prevent yellowing, cracking, and other signs of aging caused by prolonged exposure to sunlight, thereby extending the lifespan and maintaining the appearance of these materials.
4. Used in High-Performance Industrial Coatings:
For high-performance industrial coatings, Phenol, 2-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazin-2-yl-5-3-(2-ethylhexyl)oxy-2-hydroxypropoxyacts as a UV stabilizer, providing protection against the harmful effects of ultraviolet radiation. This is essential for coatings used in outdoor applications or in environments with high levels of sunlight exposure, ensuring the coatings remain effective and durable over time.
Characteristics
UV-405, also called DXSORB 405, 2-[2-Hydroxy-4-[3-(2-ethylhexyl-1-oxy)-2-hydroxypropyloxy]phenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine,Tinuvin 405 etc., is a hydroxyphenyl triazine (HPT) UV absorber designed for high performance coatings. The low volatility,high thermal stability and extended UV absorption of UV-405 provides superior protection to coatings and light sensitive substances which are subjected to extreme processing conditions and light exposure.UV-405(DXSORB 405) has been developed as an interaction-free UVabsorber to be used in amine and/or metal-catalyzed coating systems or in coatings applied on base-coats or substrates containing such catalysts.
Check Digit Verification of cas no
The CAS Registry Mumber 137658-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,5 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137658-79:
(8*1)+(7*3)+(6*7)+(5*6)+(4*5)+(3*8)+(2*7)+(1*9)=168
168 % 10 = 8
So 137658-79-8 is a valid CAS Registry Number.
