    Adhesives serve many functions in daily life, starting from sticking envelopes to rejoining broken
    materials. Adhesives are usually developed for a specific purpose and the performances can vary
    according to their specific end-use. Most of the commercially available adhesives comprised nonrenewable or petroleum derived raw materials. Thus, in order to mitigate negative impact of using nonrenewable material as the raw material for adhesives, a new type of adhesive containing epoxidised
    natural rubber (NR) latex is developed. Epoxidised NR latex adhesive was initially prepared and pigment
    was subsequently added to produce desired colours of the adhesive. Hence, the newly developed adhesive
    can serve as adhesive and also as paint for art. The adhesives were characterised and the results indicated
    that they were free from heavy metal contents and volatile organic compounds (VOCs). The adhesives
    exhibited comparable odour concentration to commercial synthetic-based adhesive. In terms of toxicity
    level, the adhesive developed exhibited low acute oral toxicity. Peel adhesion test of A4 and drawing
    papers on stainless steel and glass substrates, opacity and glossiness were also investigated in the present
    study. This coloured adhesive is deemed to support the STEM (science, technology, engineering and
    mathematics) learning by indirectly imparting polymer science and technology in art education and
    further promotes creative learning among school children. The adhesive is also derived from renewable
    material rendering it more environmentally friendly.
