Absorbency slows the rate of storm water run-off from the roof,
resulting in less water in the sewer, and less overflow of untreated
water into Long Island Sound and the East River. Two new high-performance uv absorbers: Cyasorb UV-1164
hydroxytriazine with low volatility and good solubility in most polymers
provides strong absorbency in both the UV-A and UV-B regions; and
Cyasorb UV-3638 benzoxazinone with very strong absorbency in the UV-A
and UV-B regions is extremely low in volatility and does not contribute
color to the matrix. Softness and bulk are especially important for toilet
and facial tissue and handkerchiefs, while absorbency and wet strength
are vital for kitchen rolls, towels and serviettes. |
