HD-SM-8870PU adhesive systems
HD-SM-8870PU is double-component system designed by Beijing Bora
Polyurethane Products Co.,Ltd for the bond needed of continuous
or discontinuous EPS sandwich panels,etc. B-component is modified
polyisocyanate(MDI), while A-component is made up of polyether polyalcohol,
blowing agent,catalyst and stabiliser,etc.
 HD-SM-8870
is featuring of low viscosity and applying to the technique requirements
of vertical and horizontal continuous or discontinuous production.
HD-SM-8870
has excellent adhesive performance, especially applied to two-paint
and one-drying steel board.
HD-SM-8870
has wide application for board temperature and environment temperature.
