DB 75 yog kua cua sov thiab lub teeb stabilizer tsim rau polyurethanes

Daim ntawv thov

DB 75 yog siv hauv polyurethanes xws li Reaction Txhaj Moulding (RIM) polyurethane thiab thermoplastic polyurethane (TPU). Cov khoom sib tov kuj tseem siv tau rau hauv daim ntawv thov sealant thiab nplaum, hauv polyurethane txheej ntawm tarpaulin thiab flooring nrog rau hauv cov tawv hluavtaws.

Nta / txiaj ntsig

DB 75 tiv thaiv kev ua, lub teeb thiab huab cua induced degradation
ntawm cov khoom siv polyurethane xws li khau khau, ntsuas thiab qhov rooj vaj huam sib luag, lub kauj tsheb, lub qhov rais encapsulations, lub taub hau thiab caj npab so.
DB 75 tuaj yeem yooj yim ntxiv rau cov tshuaj tsw qab lossis aliphatic polyurethane tshuab rau thermoplastic moldings, semi-rigid integral foams, hauv-pwm skinning, dope daim ntaub ntawv. Nws tuaj yeem siv nrog cov khoom siv ntuj thiab pigmented. DB 75 yog tshwj xeeb tshaj yog haum rau kev npaj lub teeb ruaj khov xim pastes rau cov saum toj no hais systems.
Cov txiaj ntsig ntxiv:
yooj yim rau twj tso kua mis, pourable kua cia plua plav dawb tuav, automated npaum li cas thiab shortening ntawm nws lub sij hawm
tag nrho cov kua pob; tsis muaj sedimentation ntawm additives nyob rau hauv lub polyol theem txawm nyob rau hauv qis kub
resistant rau exudation / crystallization nyob rau hauv ntau lub tshuab PUR

Cov ntaub ntawv khoom Clear, me ntsis daj kua

Cov lus qhia rau kev siv

Kev siv qib ntawm DB 75 ntau ntawm 0.2% thiab 1.5%, nyob ntawm seb cov substrate thiab kev ua tau zoo ntawm daim ntawv thov zaum kawg:
Reactive ob lub ntsiab lus tseem ceeb foams 0.6% - 1.5%
Adhesive 0.5% - 1.0%
Sealants 0.2% - 0.5%
Cov ntaub ntawv kev ua tau zoo ntawm DB 75 muaj rau ntau daim ntawv thov.
