Description
INTRODUCTION
DY-OH502 is a low molecular weight linear polydimethylsiloxane with terminal hydroxyl groups. Strict quality controls are observed throughout its manufacture to ensure that each molecule is functionalized with exactly two hydroxyl groups at each end of the polymer.
DY-OH502 low molecular weight hydroxyl siloxane fluid (viscosity is 20 to 30 cp, OH-group content is about 8%) is excellent structure controlling agent of silicone rubber.
