In the production and use of windshield washer fluid, excessive foam is a common and troublesome problem. Excessive foam not only affects filling efficiency and leads to underfilled packaging, but also, when consumers use the product, prevents the washer fluid from being sprayed evenly onto the windshield, directly affecting the cleaning effect and user experience. The market urgently needs a solution that can quickly and persistently suppress foam without affecting the clarity and low-temperature performance of the washer fluid.
Chemi Tech conducted an in-depth analysis of this pain point and found that the foam mainly originates from the surfactants in the formula and high-speed mechanical stirring. Traditional defoaming methods often have short-lived effects or introduce new compatibility problems. For this reason, we developed a series of defoamers designed specifically for windshield washer fluid systems. The core of this solution lies in its excellent compatibility and highly efficient foam-suppressing performance: it can quickly penetrate and destroy the foam film wall while maintaining the low-temperature stability and transparency of the washer fluid.
Our specific solution steps are as follows: first, our technical team conducts a free evaluation of the customer's existing washer fluid formula to identify the main sources of foaming. Second, based on the characteristics of the formula (such as concentrate or ready-to-use) and the process conditions, we recommend the most suitable Chemi Tech defoamer model. Then, we provide detailed dosage recommendations; usually only a very low dosage (0.05%-0.3%) is needed to take effect. Finally, we guide the customer to add it at key stages of production (such as after blending and before filling) and to conduct sufficient stability testing to ensure a lasting effect.
A typical case is a manufacturer specializing in car care products whose summer washer fluid generated a large amount of foam on the high-speed filling line, resulting in inaccurate filling volumes and residual foam at the bottle mouth that affected appearance. After adopting the defoamer recommended by Chemi Tech, the foam was quickly eliminated after stirring, the filling line efficiency increased by 15%, and no foam rebound occurred after the product was left to stand for storage; the customer was highly satisfied with the clarity and performance of the final product.
Choosing Chemi Tech means choosing professional technical support and reliable product performance. We are committed to helping every windshield washer fluid manufacturer overcome foam obstacles and enhance the market competitiveness of their products.
