Main components of mineral oil UV curing defoamer Burundi(2)
additives
levelling
Inorganic hydrophobic particles account for about 10% of the total, and they are evenly dispersed in mineral oil, which is one of the key factors because their hydrophobic strength determines the effectiveness of defoaming performance, which can help UV curing defoamer Burundi factors reach the surface of the liquid film more easily, allowing the defoaming agent to quickly blend with the liquid film to increase defoaming speed.
hardening
Alkyl modified organosiloxane
As mentioned earlier, polyether modified polysiloxanes have some shortcomings; Alkyl modified polysiloxanes have precisely these advantages.
This series of polysiloxane products also belong to the comb structure. The molecular weight of this type of product is relatively small, around 10000, and n+m is about 30-50. The main purpose of modifying with alkyl is to improve thermal stability, compatibility, and unstable foaming, and even to have defoaming functions. However, as the modified alkyl chain increases, its ability to reduce surface tension also decreases
unstable
Emulsifiers, also known asUV curing defoamer Burundi auxiliaries, aim to increase emulsifying performance, thereby increasing the normal functioning of defoamers, that is, stability. Usually, the proportion is also 10%. Generally, emulsification additives that are compatible with mineral oil and do not affect the appearance performance are selected. When mixed with mineral oil defoamers, they can play a role in the aqueous system and cooperate with defoaming factors to defoaming.
