UV-1130 Liquid UV Absorber Supplier for Coatings
SUNSORB® 1130 is a liquid benzotriazole UV absorber for automotive, industrial and wood coatings. It is easy to incorporate and is usually used together with a liquid HALS such as 292.
CAS 104810-48-2 / 104810-47-1 / 25322-68-3 · Benzotriazole · Liquid
Product Overview
UV-1130 is the reaction product of a benzotriazole propionate ester with polyethylene glycol 300, supplied as a liquid. Its PEG segment gives good compatibility in polar coating binders, including waterborne systems, while the benzotriazole absorbs UV light to protect the coating and the substrate.
Typical specification. Every shipment is supplied with a batch COA; the limits that apply to your order are confirmed in the quotation and contract.
Key Benefits
Liquid format
Blends directly without milling.
Pairs with liquid HALS
Standard partner for 292 in coatings.

Technical & Buying Information
UV Absorber 1130 Buyer Guide
Define the exposure
Indoor light behind glass, outdoor temperate climate and desert or tropical exposure need very different packages. Note the target service life and the weathering test you use (xenon or QUV, hours, ΔE or gloss retention).
Match absorber to process and thickness
A UV absorber works by filtering, so it needs enough path length: thick parts need less, thin films and fibers need more and need a low-volatility grade. Check the absorber survives your processing temperature.
Combine with a HALS
For outdoor use the standard approach is UV absorber plus HALS. Send your current package and pigment system and we suggest a starting combination for the trial.
Check regulations before you buy
Some benzotriazoles are restricted in the EU and other markets. Tell us the destination and end use, and we confirm the REACH and food-contact position of the grade before you order.

View product →UV Absorber 1130 FAQ
Is 1130 a light stabilizer or a UV absorber?
It is a UV absorber (benzotriazole). In coatings it is normally combined with a HALS such as 292.
1130 or 384-2?
Both are liquid benzotriazoles. 1130's PEG segment suits polar and waterborne binders; 384-2 is widely used in solvent-borne systems.
Is it used in polyolefins?
No, it is designed for coatings. For polyolefins use solid absorbers such as 326 or 531 with a HALS.
Can I get a sample before ordering?
Yes. Tell us the polymer, the test you plan to run and the quantity you need. Samples ship with a COA so you can compare the lot against your current material.
What if a COA does not match our agreed specification?
Send us the agreed specification and the COA showing the difference (parameter, unit and test method). We check it with the production batch record before you accept the material, and replace or re-test where the lot is out of specification.
