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 TINUVIN 292 provides significantly extended life time to coatings by minimizing paint defects such as cracking and loss of gloss. TINUVIN 292 is recommended for applications such as: · automotive coatings (non acid catalysed) · 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) · water borne acrylics · phenolics, vinylics · radiation curable acrylics The dispersion of TINUVIN 292 in water borne coatings may be facilitated by dilution with a water miscible solvent such as butylcarbitol. The performance of TINUVIN 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 colour 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 TINUVIN 292 with paint ingredients such as acid catalysts should be carefully evaluated. The amount of TINUVIN 292 required for optimum performance should be determined in trials covering a concentration range. 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. Provides significantly extended life time to coatings by minimizing paint defects such as cracking and loss of gloss. Miscible to more than 50% with most commonly used paint solvents. Recommended for automotive coatings(non acid catalysed), industrial coatings, wood stains or do-it-yourself paints, radiation curable coatings (with no loss of cure speed). Used for one- and two-component polyurethanes (water and solvent), thermoplastic acrylics (physical drying), thermosetting acrylics, alkyds and polyesters, alkyds (air drying), water borne acrylics, phenolics, vinylics and radiation curable acrylics. Dispersion in water borne coatings may be facilitated by dilution with a water miscible solvent such as butylcarbitol. Performance can be significantly improved when used in combination with a UV absorber, synergistic combinations give coatings superior protection against gloss reduction, cracking, blistering, delamination and colour change. The light stabilizers may be added in two coat automotive finishes to the base and clear coat. Optimum protection is usually achieved by adding the light stabilizers to the topcoat. Possible interactions with paint ingredients such as acid catalysts should be carefully evaluated. Recommended usage level: 0.5-2.0% based on weight percent binder solids (+ 1.0-3.0% UV absorber) for clear coats and one coat metallic shades, 0.5-2% (+ 1-3% UV absorber) for one coat solid shades.
