The CONTACTAL HPG 140173 is a specialized conductive preparation formulated mainly from mineral fats and selected fillers, including zinc, designed to improve electrical contact in aluminum connections. The composition’s controlled particle size and geometry enable the mechanical rupture of the alumina layer that naturally forms on aluminum surfaces when the joint is tightened, thereby ensuring low-resistance, stable, and corrosion-protected electrical connections. This makes CONTACTAL® HPG particularly suitable for use in power distribution, grounding systems, and aluminum conductor assemblies. Across North America, Europe, Asia, and worldwide, application methods and compliance standards may possibly vary according to regional electrical installation requirements.
