    GROTAN® BK is a broad-spectrum biocide designed for use in metalworking fluid systems to prevent microbial contamination. It effectively controls bacteria and fungi that cause slime, odors, gas formation, and pH drift in soluble oil, semi-synthetic, and synthetic fluids. Regular use of GROTAN® BK helps maintain fluid stability, extend service life, and reduce downtime and maintenance costs in metalworking operations.

    What makes Blachford the leader in wire drawing?

    A globally deployed portfolio with low-dust, low-consumption chemistries, the proprietary SMART System for data-driven selection, custom formulations for high-tech segments, eco options (lime/borax substitutes), and fluid recycling—validated by extensive field data across 20+ countries / 5 continents.
    SMART maps your wire grade, die geometry, reduction schedule, and targets to a short-listed chemistry and usage plan—cutting trial-and-error, accelerating qualification, and improving ROI with recommendations backed by global field data.
    Cleaner machines (low dust), lower total lube consumption, longer die life, better surface quality, and more stable speeds—outcomes reported consistently in demanding production environments.
    Yes. We supply custom-engineered solutions for welding wire, spring wire, PC strand, tire bead/cord, stainless, galvanized, and non-ferrous applications, with product families tuned to each use case.
    Examples include CHEMDRAW® S31L, 644 N, DX557 (spring); CHEMDRAW® 7607 (PC strand); CHEMDRAW® 228, 838, 644-N (galvanized); CHEMDRAW® WL1084, 701, 2001 (copper & aluminum); and CHEMDRAW® BSS-2 (lime/borax substitute). Your final shortlist is generated via SMART.
    Lime/borax-free options (e.g., BSS-2) reduce environmental load and housekeeping; low-dust chemistries support cleaner, safer conditions; recycling programs for non-ferrous cut usage and disposal. Some customers have seen up to ~50% cost reduction with eco substitutions.
    A structured, SMART-guided trial plan (targets, usage, success criteria), on-line technical support, and rapid data reviews—so validation is predictable and scale-up is straightforward.
    We serve manufacturers and OEM/Tier 1 suppliers in automotive, infrastructure/construction, shipbuilding, mining, oil & gas, appliances, fencing, and specialty producers, with supply and technical support across 20+ countries on 5 continents.
