BS EN 1243 specifies a method for the determination of the free formaldehyde content in amino and amido-formaldehyde condensate adhesives.
The reaction of the free formaldehyde with sodium sulfite, in the presence of a measured excess of acid and alkaline titration of the unreacted excess acid.
BS EN 1243on Adhesives is useful for:
Any substance that is capable of holding materials together in a functional manner by a surface attachment that resists separation is known as adhesives.
BS EN 1243 can help in conducting tests to determine the free formaldehyde in amino and amidoformaldehyde condensates. These test methods assess the sustainability of these adhesives in different climatic conditions.
A world-class adhesive standard, BS EN 1243 provides a step-by-step guide to ensure superior quality of adhesives by detecting free formaldehyde in amino and amidoformaldehyde condensates and offers a cost-effective, sustainable solution to the adhesive industry.
