Rubber farmers often sell products in the form of raw rubber materials, which the price is relatively low compared to the price that can get by selling in the form of rubber products. Therefore, if the natural rubber product processing is encouraged, it will help the farmers to gain more salary. Objective: To develop rubber compound to create souvenirs in the community for tourism in Satun Province Methods: Experimental mixing latex with chemicals in various formulations Including studying the types and amount of viscosity additives to obtain the appropriate viscosity for each type of fabric painting leading to a good adhesion between rubber and fabric fibers when the latex is dry. Results: The appropriate viscosity of latex in painting fabrics is in the range between 1000 - 1100 centipoise (cps). The suitable rubber formula for painting on dark fabrics obtained by using titanium dioxide (TiO 2 ) because the color can be seen clearly and the dry rubber line doesn’t shrink. Conclusion : This study found that the natural rubber latex can be used in drawing patterns on batik fabric, painting on the shirts and bags. Keywords: Natural rubber latex, fabric painting, Satun province
