Technical Data Sheet
BETASEAL 1527
Description / Application:
Aftermarket Division
One-component, medium-viscous, humidity-curing polyurethane bonding/sealing compound for direct glazing
with fast link up and short drive away time. In addition it has a high shear modulus, very low volume resistivity
and good high-frequency-properties. Due to these characteristics of Betaseal 1527, a higher body stiffness and
full compatibility to glass-integrated antennas can be achieved. It must be used in combination with a Glass
Cleaner and RIM and PAAS Activator and a Glass and Body Activator.
All Dow Automotive products are primarily developed in co-operation with the automobile
manufacturers, according to their needs and their specifications; they are approved for the specific
applications as defined by the customer.
The use of the product other than approved application have to be released in written form by the
Technical Service of Dow Automotive.

Cleaning Uncured Betaseal 1527 residues can easily be removed with
BETACLEAN 3500. Hardened Betaseal 1527 residues can
only be removed mechanically. Immerse equipment in
BETACLEAN 3350.
