In asphalt production and construction, foam problems often trouble many practitioners. Excessive foam not only occupies effective equipment volume and reduces production efficiency, but may also cause uneven density of the asphalt material and defects on the coating surface, ultimately affecting the overall performance and appearance quality of the product. Traditional methods often defoam slowly, have a short-lived effect, and may even introduce other compatibility problems.


In response to these market pain points, drawing on professional R&D, Chemi Tech has launched a series of high-efficiency defoamers for water-based asphalt. Our solution is not simple addition, but is based on a deep understanding of the foaming mechanism of asphalt systems. The product uses specially modified polysiloxane and composite technology, which can quickly penetrate and destroy the foam film, achieving a balance between instant defoaming and long-lasting foam suppression. It has excellent compatibility with water-based asphalt systems and will not produce surface problems such as fish eyes or cratering, ensuring the intrinsic quality of the asphalt material and smooth construction.


The specific application steps are clear and simple. First, according to the specific formula and process conditions of the asphalt system, our technical team will assist the customer in conducting small-sample tests and recommend the most suitable defoamer model. Second, determine the best addition point, usually recommended to be added before the process stage that is prone to foam generation. The dosage is generally in the range of 0.1% to 0.5%, and the specific amount needs to be optimized through experiments. Finally, it can be uniformly dispersed by conventional stirring, with no special equipment required, and can be easily integrated into the existing production line.


We once assisted an asphalt products company in solving the stubborn foam problem generated during high-temperature stirring and filling of its products. The additive previously used by the company had low defoaming efficiency, resulting in inaccurate filling volume and surface defects on the product. After adopting Chemi Tech's customized defoamer solution, the foam was effectively controlled at the stirring stage, filling efficiency increased by about 15%, product appearance consistency was significantly improved, and customer satisfaction rose greatly.


Choosing Chemi Tech means choosing a reliable defoaming solution and professional technical support. We are committed to helping every customer overcome foam difficulties and enhance the market competitiveness of water-based asphalt products.
