Technical Data

Description Tiangang® C102 is a versatile liquid UV stabilizer system that can be used to protect polymers from UV degradation. Tiangang® C102 provides light protection to polyurethane systems such as microcellular and integral skin foams, traditional rigid, semi-rigid and flexible foams, fabric coatings for synthetic leather, but also to some adhesives, sealants and elastomers. The product can also be used in other polymeric systems where a liquid light stabilizer is preferred.
Tiangang® C102 is highly soluble in many solvents, and can achieve homogeneous dispersion in most liquid systems easily.

Frequently asked questions

How is C102 different from buying HALS and UVA separately?

C102 pre-mixes a HALS with a UV absorber at a synergistic ratio in a liquid carrier. That removes two steps: ratio trials and a second weighing/dispersion. Self-blending is more flexible, at the cost of re-verifying dispersion on every batch.

How should a liquid product be dosed into a solvent-borne system?

Pre-mix with the solvent or a resin component before addition; avoid dumping it straight into a high-shear stage. Pre-mixing gives a uniform distribution and makes the actual dose easy to reconcile per batch.

What should be watched when used in polyurethane?

Catalysts and some co-additives in a PU formulation can affect how the stabiliser performs. Run a lab trial on compatibility and storage stability before scaling up. With a liquid product, check for separation at low storage temperature in particular.
