Introduction
1. Scope and applicability of the standard
GB/T32371.4-2015 specifies the method for determining the release characteristics of volatile diisocyanates after the application of low-solvent or solvent-free adhesives. This standard is applicable to the measurement of volatile diisocyanates released from surfaces in a short period of time, mainly for adhesives, coatings and related products.
2. Background of standard formulation and technological evolution
With the improvement of environmental protection requirements, the application of low-solvent and solvent-free adhesives is becoming more and more extensive. As a potentially harmful substance, the detection of volatile diisocyanates has become an important part of product quality control. This standard is formulated based on internationally accepted methods (such as ISO16702) and combined with China's actual situation to ensure the scientificity and applicability of the detection method.
