Abstract
Due to the environmental concerns of solventborne coating systems, environmental directives have recently been promulgated in many countries. Additionally, integrated environmental policies have been pushed in many fields to minimise influences on the environment. Waterborne silicon acrylic finishers have gained much interest to replace the traditional finishing system. To satisfy the requirements, a waterborne finisher with polyamide was previously developed and its performance was determined. For further safety assessment, various tests were conducted, such as gas toxicity, heavy metals tests, chemical resistance test and chloride migration test, followed by equivalent standards. In the cases of gas toxicity and heavy metals evaluations, both results were acceptable considering their corresponding standards, e.g. KS F 2271, KS F 3888-2 and BS EN 71-3. Based on the evaluation, silicon acrylic with 30% mix ratio of polyamide resin (SA+PR30%) could be implemented as an environmentally friendly finisher for various applications. In the chemical resistance and chloride migration test results, the developed finisher showed a barrier effect in the chemical environment. Thus, the developed finisher could be an alternative finisher applicable for slabs in chemical industrial areas.
Highlights
Surface finishing materials are extensively used in various fields of applications, especially car park slabs, because underground car park concrete pavement has the major environmental issue of fine dust creation by repetitive loads from tires and the lack of air circulation system
The gas toxicity test was conducted to determine the gas toxicity of the developed finisher by exposing lab mice to the combustion gas according to KS F 2271
All outcomes of safety tests conducted in this study showed that silicon acrylic (SA)+PR30% is eco-friendly and has chemical and chloride resistance properties
Summary
Surface finishing materials are extensively used in various fields of applications, especially car park slabs, because underground car park concrete pavement has the major environmental issue of fine dust creation by repetitive loads from tires and the lack of air circulation system. Among the current techniques to prevent this issue, the implementation of organic coatings is considered as an economical approach to offer a comfortable underground car park condition to customers [1,2,3]. Typical top finishers such as epoxy and urethane, which are solventborne organic, are well-known and commonly applied in practice because they are cost effective, durable, waterproof, and non-slip [2,4]. Environmental issues, the transmission of Volatile Organic Compounds (VOCs) to the air, are associated with the application [5]. Uncomfortable scent and environmental hormones from the solvent or epoxy, in an enclosed working environment, mean workers could be subjected to dangerous situations and fire incidents might occur [1,2]
