LIGHT STABILIZER 292 (CAS:41556-26-7/82919-37-7)

LIGHT STABILIZER 292

CAS No.[41556-26-7/82919-37-7]  a) Bis (1, 2, 2, 6, 6-pentamethyl-4-piperidyl) sebacate & b) Methyl 1, 2, 2, 6, 6- pentamethyl-4-piperidyl sebacate

Light stabilizer 292 is a liquid hindered amine light stabilizer especially developed for coatings. It is  an almost pure mixture of the two active ingredients below. It is this combination that keeps  the product liquid, unlike the pure diester which tends to solidify, even at room temperature.  The efficiency of Light stabilizer 292 provides significantly extended lifetime to coatings by  minimizing paint defects such as cracking and loss of gloss.

Features & Benefits

- Versatile HALS with superior performance in both water- and solvent-based coatings 

- Extends usable lifetime of coating by minimizing loss of gloss and cracking  

- Excellent compatibility with a wide variety of coatings systems

Applications

Light stabilzier 292 is recommended for applications such as:  

• automotive coatings (non-acid catalyzed)  

• industrial coatings  

• wood stains or do-it-yourself paints  

• radiation curable coatings (with no loss of cure speed)

Its high efficiency has been demonstrated in coatings based on a variety of binders such as: 

• one- and two-component polyurethanes (water and solvent)  

• thermoplastic acrylics (physical drying)

• thermosetting acrylics, alkyds and polyesters 

• alkyds (air drying) 

• waterborne acrylics 

• phenolics, vinylics 

• radiation curable acrylics

The dispersion of  UV 292 in waterborne coatings may be facilitated by dilution with a water miscible solvent such as butylcarbitol. 

The performance of UV  292 can be significantly improved when used in combination with a UV  absorber such as recommended below. These synergistic combinations give coatings superior  protection against gloss reduction, cracking, blistering, delamination and color change.  

The light stabilizers may be added in two-coat automotive finishes to the base and clear coat.  However, according to our experience the optimum protection is usually achieved by adding the light  stabilizers to the topcoat. 

Possible interactions of UV  292 with paint ingredients such as acid catalysts should be carefully  evaluated.  The amount of UV 292 required for optimum performance should be determined in trials  covering a concentration range.
