BONDERITE® L-MR B-637 is a semi-synthetic cutting fluid designed for machining and grinding ferrous and aluminum alloys. Its innovative bio-resistant technology plays a crucial role in actively preventing biofouling within the tank. This eliminates the need for tank-side biocides and significantly reduces maintenance requirements while maintaining the system's cleanliness. The fluid's outstanding cooling performance and high lubricity make it highly suitable for an extensive range of machining and grinding applications, ensuring precision and quality in every operation. This fluid is also low foaming to sustain lubrication, cooling, and machine performance. BONDERITE® L-MR B-637 is expertly formulated to provide superior tramp oil rejection, allowing for easy removal and extending the fluid's life, consequently improving tooling performance and lifespan. Its exceptional wetting and emulsion properties are designed to minimize product consumption, thereby reducing operational costs. Additionally, it is formulated without boron, rendering it an environmentally sustainable coolant that meets the growing demand for eco-friendly industrial solutions. Such comprehensive features make BONDERITE® L-MR B-637 an indispensable asset in the metalworking sector, driving both performance and sustainability.

Biofouling in the tank poses a significant issue for metalworking professionals, manifesting as unpleasant odors, particularly noticeable after weekends when machines have been idle. These "Monday morning odors" result from microbial growth, which can also compromise machine cleanliness and worker comfort. The presence of biofouling necessitates frequent maintenance and cleaning, leading to increased downtime and operational inefficiencies. Furthermore, heavy-duty machining often subjects tools and parts to considerable wear and damage, reducing their lifespan and resulting in higher replacement costs. This can severely impact production schedules and overall productivity, as tools and parts may need to be replaced more frequently. Additionally, processes can result in tanks and parts being left dirty post-machining, which affects the final product's quality and demands additional cleaning efforts and resources. Another challenge in the metalworking environment is the excess consumption of machining fluids, which can significantly increase operational expenses. Because boron can have adverse effects on the environment and human health, metalworking fluids formulated with boron can present a problem to manufacturers trying to reduce their environmental footprint or meet environmental regulations.
