Characterization

DB 75 ndeyekupisa kwemvura uye chiedza stabilizer system yakagadzirirwa polyurethanes

Application

DB 75 inoshandiswa mu polyurethanes yakadai seReaction Injection Molding (RIM) polyurethane uye thermoplastic polyurethane (TPU). Iyo musanganiswa inogona zvakare kushandiswa mu sealant uye inonamira maapplication, mune polyurethane coating pa tarpaulin uye pasi pamwe neyakagadzirwa dehwe.

Features/benefits

DB 75 inodzivirira kugadzirisa, kujeka uye mamiriro ekunze anokonzera kudzikisira
yezvigadzirwa zve polyurethane zvakadai sezvigadziko zveshangu, chiridzwa uye mapaneru emasuo, mavhiri ekutungamirira, mahwindo encapsulations, musoro uye maoko.
DB 75 inogona kuwedzerwa nyore nyore kune inonhuhwirira kana aliphatic polyurethane masisitimu e thermoplastic moldings, semi-rigid yakakosha mafuro, in-mold skinning, dope application. Inogona kushandiswa nezvinhu zvakasikwa uye pigmented. DB 75 inonyanya kukodzera kugadzirira mapete emavara akagadzikana ezvirongwa zvataurwa pamusoro apa.
Zvimwe zvinobatsira:
nyore kupomba, mvura inodururwa inobvumira guruva kubata, otomatiki dosage uye kupfupisa kwekusanganisa nguva.
yese yemvura package; hapana sedimentation yezvinowedzera muchikamu che polyol kunyange pakupisa kwakadzika
inopesana neexudation / crystallization mune akawanda PUR masisitimu

Mafomu echigadzirwa Zvakajeka, zvishoma yero mvura

Nhungamiro dzekushandisa

Matanho ekushandisa eDB 75 anosiyana pakati pe0.2 % ne1.5 %, zvichienderana ne substrate uye kuita zvinodiwa zvekupedzisira application:
Reactive maviri-chikamu chakakosha furo 0.6 % - 1.5 %
Adhesives 0.5 % - 1.0 %
Sealants 0.2% - 0.5%
Yakawedzera performance data yeDB 75 iripo kune akawanda maapplication.
