Investigation into the efficacy of wood apple gum and natural plant extracts for natural sustainable surface coating development.

Abstract

For wall coatings on both interior and exterior surfaces, numerous substances can be used to improve aesthetics, protect against weathering, and provide practical advantages. These coatings provide walls with resilience, water resistance, and aesthetic value while also functioning as a layer of protection. The development of a natural surface coating made of plant extracts is critical for long-term sustainability. A natural surface coating is an environmentally conscious alternative to synthetic coatings. Our study prioritizes using plant extracts in the coatings to reduce harmful effects associated with the current coating industry and as a reaction to the growing demand for environmentally conscious products. Furthermore, it can boost local economic growth by using resources, preserve traditional knowledge, and limit the usage of toxic chemicals. This holistic approach promotes sustainability, environmental stewardship, health and safety, and cultural preservation. The experimental emphasis of the research is on the production of a natural surface coating utilizing wood apple (Limonia acidissima) gum and other natural extracts. The methods included coating formulation, testing, and application, as well as determining the best extraction technique for wood apple gum. There were four treatments in the study such as 20%, 50%, 60%, and 80% of wood apple gum with Dorana (Dipterocarpus glandulosus) oil and Haldummala (Trachylobium verrucosum), named as T1, T2, T3, and T4 respectively. This investigation explored the complex properties of coatings, looking closely at water resistance, viscosity, adhesion, pH levels, and aesthetic appeal. From the study, it was identified that horizontal cut that was 100% depth was the most effective technique to extract wood apple gum. The top-performing treatment (T1) obtained a level 5B rating in adhesion and it exhibited ideal pH ranges and viscosities comparable to those of available wall coatings in the market. Furthermore, T1 showed the maximum hardness level (8H), while all treatments showed promising signs of water resistance. The findings of this study may have a substantial influence on several sectors through the provision of environmentally friendly substitutes, reduction of environmental impact, enhancement of public health and safety, promotion of innovation, creation of new business opportunities, fulfilment of customer demands, and preservation of traditional values.
