Mix-Ratio Tolerance Checker (±5%)

Off-ratio mixing cuts bond strength, chemical resistance and Tg. Enter your nominal and measured volumetric ratio to see whether you are inside the ±5% window — and remember 1:1 is more forgiving than 4:1, and 4:1 more forgiving than 10:1.

Reference: ±5% is the widely cited working tolerance for two-component adhesives (per adhesive TDS). A dimensionally stable barrel and square, sealed piston hold the ratio across a long 400/600 ml stroke.
