NJ-505 defoamer
NJ-505 defoamer is a polyether surfactant formulation with dry powder carriers, featuring:
It effectively suppresses bubble formation and rapidly removes bubbles introduced through mechanical agitation or chemical reactions in mortar, maintaining long-lasting foam control.
The product completes defoaming within 40-90 seconds after mortar mixing and can be stored for extended periods when blended with cement mortar materials.
Particularly suitable for systems requiring high density, such as grouting compounds, grout formulations, and bearing mortar. Note: Its defoaming efficacy may be reduced in low-temperature environments, making it unsuitable for winter use.

NJ-507 defoamer
NJ-507 defoamer is a mixture of polyether surfactant and dry powder carrier, with the following characteristics:
This product can inhibit the generation of bubbles for a long time, and quickly discharge the bubbles introduced into the mortar by mechanical stirring or chemical reaction.
Generally, the defoaming can be completed within 20~40s after the completion of mortar mixing, and it can play a stable role in the environment of-5~45℃.
This product can be mixed with cement mortar materials and stored for a long time.
This product is particularly suitable for systems with surface condition or density requirements, such as surface self-leveling, grout, UHPC, etc.
scope of application
Compaction agent material； Grouting mix； Self-leveling cement； UHPC； exterior wall putty； Gypsum board ；Adhesive mortar； Plaster application ；Waterproof mortar； Decorative mortar

NJ-506H defoamer
NJ-506H is a defoaming agent specially launched for the high temperature construction environment in summer. Under the condition of high temperature, the performance of conventional defoaming agent decreases, resulting in bubbles trapped in the slurry and unable to be discharged, forming bulges. This product has the following characteristics:
NJ-506H can maintain good defoaming performance in high temperature environment, quickly discharge the bubbles introduced by mechanical stirring or chemical reaction in the mortar, and can eliminate the black oil and black spots on the surface of the slurry. Usually, the defoaming can be completed within 40~90s after the completion of mortar mixing.
It can be mixed with cement mortar materials and stored for a long time. It is especially suitable for systems with surface requirements, such as surface self-leveling, grout, and cement and gypsum prefabricated components.
