BTR™ Polyurethane Binders

Quite simply, we carry the best binders in the business. OTS binders are formulated specifically for the Poured-in-Place surfacing industry for the bonding of rubber resilient surfaces. It is manufactured with a proprietary castor oil based polyol and a non-solvent based wetting agent that lowers the trowel drag coefficient during installation.

BTR™ binders are available for several climate characteristics, including extreme conditions. Choosing the best binder for the prevailing weather improves working conditions for the installer, and assures that the installer will be able to perform his best work.

Variations of temperature, dew point and humidity affect the cure rate and workability of PU binders. Conversly, high temperatures combined with high humidity result in a fast cure of the surface. Likewise, lower temperatures or humidity will extend the curing time. Consequently, our BTR™ binders are formulated with specific amounts of catalyst and wetting agents to accommodate a wide range of installation issues.  The choice of a particular binder is based not only on the prevailing weather conditions, but the ability of the installer to plan and execute his work at a speed that allows the workmen to trowel a tight and smooth surface finish.

BTR™-1110  is an aromatic MDI binder containing UV stabilizers to reduce ambering from exposure to sunlight. It is suitable for use in high temperatures and high humidity conditions, and has slow curing characteristics.


BTR™-1119 is an aromatic MDI binder with UV stabilizers for use in high temperatures with low humidity (arid conditions).

BTR™-1119-W is an aromatic MDI binder with UV stabilizers and modified viscosity for low temperatures and low humidity or for cool and damp conditions.

BTR™-1103-UV is an aliphatic binder with the highest UV protection available to prevent ambering from exposure to sunlight. It has slow curing characteristics, unless ordered with special catalysts. See Technical Data Sheet #2 for additional information about this binder.

BTR™ binders are shipped in sealed containers and must be protected against moisture. They are packaged in 5 gallon pails (44#), 55 gallon drums (465#) and totes (by special order).  Every shipment is quality controlled and traceable by serial number on each pail or drum.
