SMTEK’s chemical leak detection tapes are designed and manufactured by blending color-changing materials and adhesives. Our chemical leak detection tapes can be served as a product that allows workers to early detect leakage areas of acid, alkaline or solvent. The features are as follows: 1) instant response to acid, alkali, or solvent; 2) clear and gradual color change as time passes; 3) improved visibility and color fastness.
