invely defoamer


Our Spring festival is coming in next week, Thanks for your supports, my friends, i hope you has great success in 2020! By the way: our office and factory will closed on next week, and will back to work on Feb, 03, 2020, However, you can contact me freely if anything, i will reply you whithin 24 hours. Below is my last shipment to Shanghai Port before our holiday! antifoam defoamer invelychem

The magical effect of fumed silica in silicone rubber

The magical effect of fumed silica in silicone rubber Fumed silica is one of the most important high-tech ultra-fine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, It has specific properties in terms of electrical resistance, etc. Its superior stability, reinforcement, thickening and thixotropic properties are unique in many disciplines and fields and have an irreplaceable role. Today, Xiaobian will work with you to learn how to apply fumed silica in silicone rubber. Application of fumed silica in high temperature vulcanization (HTV) silicone rubber The use of fumed silica can be divided into silicone materials and other fields, in which the amount of silica in the silicone material is nearly 60%, and the silicone rubber is the most used material in the silicone material. It can be added in an amount of up to 50% ...

How do we assess antifoam efficiency ?

How do we assess antifoam efficiency ? Quality of an antifoam is given by two main characteristics : • Knockdown ability or shock effect :Meaning the speed to destroy an existing foam. • Persistence or durability : Meaning the efficiency over time.   These two parameters can be assessed by several tests. The main test is the bubbling method. A graduated column with a glass frit in the bottom is required. Foaming water is poured in the column and air at constant flowrate is introduced through the glass frit in the column. Foam is generated by the air and starts to travel up the column. At a determined level of foam, antifoam is injected. By this method several antifoaming agents can be tested. A graph reporting foam height vs time is very helpful to establish the knockdown ability and the persistence for each product. The selected antifoam is the product with the best compromise between shock effect and durability       Environmental performance   Silicone antifo...

Why is there foam in the paint and coating? What we should do to eliminate foam?

Why is there foam in the paint and coating? What we should do to eliminate foam?             check below details:           Surface tension The surface tension of the coating has a great influence on the defoaming agent.  The surface tension of the defoaming agent must be lower than the surface tension of the coating. Otherwise, there is no defoaming and foam suppression. The surface tension of the coating is a variable factor, so a constant surface tension is required when using the defoamer, and then the surface tension variation factor is taken into account. The influence of other additives Surfactants used in coatings are mostly functionally incompatible with defoamers. In particular, emulsifiers, wetting and dispersing agents, leveling agents, thickeners, etc., have an effect on the effect of the antifoaming agent. Therefore, we must pay attention to ...
