Organoclay in Industrial Sealants: Achieving Optimal Flow and Anti-Sag Properties

Organoclay in Industrial Sealants:If you find that the paint coating has layered lumps, need to stir half an hour to use, which will lead to a lot of users complain about low productivity, then organoclay bentonite applied to paint, can effectively solve this precipitation problem. Because organophilic clay bentonite has good anti-sedimentation.

Organo clay bentonite need to do pre-gel activation, according to its temperature and stirring speed to decide. If you store paints and coatings for a long period of time, delamination usually occurs. This delamination of pigments or fillers and the appearance of lumps can be solved by the addition of organoclay bentonite clay.

Addition of organo clay bentonite, in different stages, it will affect the thixotropy and rheology, first of all in the preliminary stage, we can first add 50%, in the grinding stage add 30% in the paint mixing stage add 20%. This is one of the best steps to add organo bentonite clay. If you add a certain amount of ethanol or methanol in the organo bentonite clay, can effectively play the role of activation, in this case on the dispersion is a positive effect.

Organophilic clay bentonite added to the paint coating, if the gel transparency is too high, usually the activation time is not enough, if there is a serious thickening after the general is the error of polar solvent matching. Then if the anti-settling effect is poor, usually because there is no pre-gel treatment.
