Efficient liquid UV absorber

Juni 23, 2021
blog

The Omnistab UV 1 is an efficient liquid UV absorber, which can absorb ultraviolet light from 240-330nm. It absorbs almost everything in the 300-330nm waveband. Based on its excellent UV absorption function and good compatibility with epoxy resin, the applications vary from adhesives, potting glues and crystal glues. Especially suitable for outdoor use where we require high weather resistance.

Polyurethane with liquid UV absorber

Polyurethane is easily degraded by radiation in the range of 300-330nm. However, the light yellow liquid UV absorber can effectively inhibit the photocatalytic degradation of polymers. It improves the color stability of the product and extends the service lifetime of the product.

Applications

The polyurethane products with above requirements are, for example, microcellular foam, integral foam, traditional rigid foam, semi-rigid foam, soft foam, fabric coating, adhesives, sealants and elastomers. It is also an efficient liquid UV absorber for PVC applications and acrylic resins. In general, it has excellent light stability in the above polymers.

Synergistic effect

The Omnistab UV 1 has synergistic effect when used in combination with Omnistab LS 292 and Omnistab AN 1010. Especially for PU resin, PU Leather and PU soft foam. As a UV absorber with excellent performance, the market for this product is wide.
