Characterization

DB 886 ndeye yakakwira performance UV inodzikamisa package yakagadzirwa

ye polyurethane masisitimu (semuenzaniso TPU, CASE, RIM inochinjika furo application).

DB 866 inonyanya kushanda mu thermoplastic polyurethane (TPU). DB 866 inogona zvakare kushandiswa mu polyurethane coatings pa tarpaulin uye pasi uye mukugadzirwa kwematehwe.

Applications

DB 886 inopa yakasarudzika UV kugadzikana kune polyurethane masisitimu.

Kuwedzera kwekuita pamusoro peakajairwa UV stabilizer masisitimu anonyanya kutaurwa mune yakajeka kana yakareruka mavara TPU application.

DB 886 inogona zvakare kushandiswa mune mamwe mapolymers akadai se polyamides uye mamwe mapurasitiki einjiniya anosanganisira aliphatic polyketone, styrene homo- uye copolymers, elastomers, TPE, TPV uye epoxies pamwe nema polyolefins uye mamwe organic substrates.

Features/benefits

DB 886 inopa kushanda kwepamusoro uye kuwedzera kubereka

pamusoro pezvakajairwa mwenje kudzikamisa masisitimu:

Yakanakisa ruvara rwekutanga

Kuchengetedza kwemavara kwepamusoro panguva yekuratidzwa kweUV

Kuvandudzwa kwenguva refu-kupisa-kugadzikana

Imwe-yekuwedzera mhinduro

Easy dosable

Chigadzirwa chinoumba Muchena kusvika kuyero zvishoma, hupfu husina kuyerera

Nhungamiro dzekushandisa

Shandisa mazinga eDB 886 kazhinji ari pakati pe0.1% ne2.0%

zvichienderana ne substrate uye kugadzirisa mamiriro. DB 866 inogona kushandiswa yoga kana musanganiswa nezvimwe zvinoshanda zvinowedzera senge antioxidants (yakavharirwa phenols, phosphites) uye HALS light stabilizers, uko kazhinji kuita synergistic kunoonekwa.
