Specialty PU resin as plugging agent
Release time：2025-01-15 Views：132
Component:
COHSIN-3121A
WINNATE-5022B
WINCURE-5050
Application:
·Used as plugging agent for oil-drilling industry.
Advantage:
·Adjustable product portfolio upon underground temperature
·Flexible pot-life (2~6 hrs) for wide process window
·Low viscosity for pumping and pipe delivery
·Faster solidation after gelling than that of Epoxy solution
·Moderate thermal release than that of Acrylate solution
·No-foaming issue like common PU system with underground water
·Suitable for underground temperature (≤120℃)
