 DM233FC Flooring polyurethane adhesive

Substrate: PU polymer

DM233FCis a one-component, solvent-free, fast-curing elastic binder for bonding wood floor, based on PU polymers, moisture curing type. The curing speed of mortar is related to the temperature and humidity of the environment. Under high-temperature or high-humidity conditions, it will be quickly crusted. Low-temperature and low-humidity will delay the curing process. The final curing time is also related to the thickness of the glue applied.


DM233FCis a special adhesive for flooring project, with moderate modulus, good thixotropy, moderate elongation, good elasticity, suitable for all kinds of porous and non-porous materials, with good adhesion, surface coating paintis available. Itis a professional adhesive that is specially used for interior decoration.


Features & Advantages                    

White, grey, beige colors available, other colors can be customized.


Odorless, low VOC, PVC free, safe to use.

Good resistance to cold and hot weather alternation, over 10 years of service life.

After curing, the shrinkage rate is very low, and the Thixotropy is good, the form during construction can be maintained well.

It can be applied for the sealing of all kinds of interior decoration materials in the room.

Low temperature resistance, in the range of -40 ~ 90 , can maintain good flexibility and adhesion.

No primer required.


Typical applications

DM233FC is suitable for solid wood, engineering wood flooring (batten, strip, plank, veneer and wood board, etc), parquet, industrial wood flooring, veneer and cardboard, the elastic sealing of most substrate joints, including stainless steel, aluminum, copper, PVC, polyester, ceramics, wood, coating, etc. It is widely used for the sealing of kinds of floors in interior decoration and waterproof treatment.


Application tips

The bonded surface must be clean, dry and free of putty before bonding.

Substrates that may seep out of oil are not suitable for direct application of sealant.

For rusted or corroded metal surfaces (such as aluminum oxide, copper, iron oxide rust surface), in order to ensure the bonding effect, the rust on the surface layer needs to be worn off before coating.

Due to the construction environment, construction methods, and material differences, pre-testing is required before use to ensure adhesion performance.

The optimal coating temperature is +15 ~ +40°C. When the temperature is low, the extrusion resistance increases, warm up the adhesive before use.
