ANTIFOAM P2 - New siliconic defoamer in powder form

ANTIFOAM P2

Pentachem formalizes the introduction on the market of its new defoamer additive ANTIFOAM P2, a direct evolution of the already highly performing ANTIFOAM P.

Keeping true to his beliefs and to the continuous research for innovative solutions that can simplify the work or perform more efficiently to its customers' products, since much time Pentachem was working to an evolution of its silicone-based defoamer Antifoam P in order to realize an updated, more performing in terms of abatement of the foam and with different characteristics in relation to the type of air bubbles which is able to remove.

This research resulted in the formulation of ANTIFOAM P2 that, thanks to the use of manufacturing processes specific to the purposes and to the synergy found between new raw materials, guarantees a level of efficiency even higher than the previous Antifoam P acting more broad-spectrum on size of the microbubbles that can break down.

In the chart we highlight the performance of the silicone-based defoamer Antifoam P2 comparing it with competing products silicone-based, polyol-based or polysiloxane-based. The graph shows that, even at very low dosages, ANTIFOAM P2 is able to operate an extremely high reduction of the air content and is therefore able to operate near the maximum efficiency even when added in very small quantities.


                                                 

In the below attached charts we show the effect of different defoamers on the consistency and on the air content of a low thickness self-leveling reference mortar:

                                                       

 

 

The analysis immediately shows that even following a high abatement of air, which normally acts as a lubricant in the mortar, there is no decrease in the flowability of the same mortar, since the flow remains almost unaltered despite having eliminated over 80% air initially present.

It is important to underline that, contrary to many other defoamers available on the market, both Antifoam P and ANTIFOAM P2 do not negatively affect the development of the compressive strength at the early and at the long-time seasoning; in the following charts we show the compressive strength of a standard mortar and of a low-thickness self-leveling grout:

  

 

The use of Antifoam P2 is recommended in all formulations based on hydraulic binders in general, such as cement, lime or gypsum and in particular in all those products where the lowest air content is required, such as stucco, smoothing finishing, skim finishing or self-leveling products.

 

Antifoam P2 can be used in both neutral and alkaline systems and it is compatible with all of the foaming agents, with redispersible powders and with all the additives normally used in the formulation of dry premixed mortars in general.
