What is Paint Testing?
Paint testing refers to the evaluation of paint products to verify their performance, quality and durability. This includes evaluation of the adhesion, abrasion and weathering resistance, color retention, corrosion protection and antimicrobial performance of the paint. These evaluations are used to gauge the effectiveness of the paint for various applications.
Characterization of Coating Testing
Characterization of coating testing involves assessing the physical, chemical and mechanical properties of coatings that allow manufacturer to draw conclusions on their suitability for specific uses. These tests include assessing parameters such as thickness, adhesion, hardness and surface texture, among others. It is also possible to determine corrosion resistance, weatherability and chemical stability under various conditions by testing coatings rigorously. These tests ensure coatings perform effectively, providing protection and durability while meeting industry standards.
Types of Paint Testing
Paint testing can be categorized into various types depending on their evaluation parameters. For example, adhesion testing, abrasion resistance testing, weathering testing and corrosion testing are performed to evaluate durability and performance. Paint tests also cover color and gloss testing, chemical resistance and antimicrobial testing to ensure protection against microbes.
Paint Testing laboratory
Ordinary paints and coatings are highly susceptible to microbial attacks. This susceptibility to microbial attacks is largely due to the presence of organic matter in paints and their high moisture retention capacity. The growth of microorganisms on paints and coating can pose health risks and property damage, which in turn increase health, maintenance and repair costs.
To overcome this challenge, antimicrobial paints and coatings have been developed to avoid microbial growth and control surface contamination. These paints and coatings treated with antimicrobial agents protect the product against discoloration and material degradation, hence enhancing the shelf life of the product. However, they must be tested before marketing for validation of their efficiency against microorganisms. Paint testing laboratories offer a wide range of microbial testing services to assure that these coatings meet the required industry standards.
International Standards for assessing the Antimicrobial activity of Paints and Coatings
Various international standards provide test methods for evaluating the microbial resistance of paints and coatings. These include
- ASTM D2574: Test for evaluating the antimicrobial resistance of emulsion paints
- ASTM D4783: Test for determining the resistance of adhesive preparations in the container to attack by bacteria, yeast and fungi
- ISO 21702: Standard to measure the antiviral activity on plastics and other non-porous surfaces
- ASTM D5589: Test to evaluate the resistance of paint films and related coatings to algal defacement
- ASTM D5590: Test method for evaluating the resistance of paint films and related coatings to fungal defacement
- ASTM D4300: Standard for determining the efficacy of adhesive films to support or resist the fungal growth
- ASTM D3273: Test for evaluating the susceptibility of interior coatings to mold development
- ASTM D7855: Test method for the determination of mold growth on coated building products designed for interior applications

Why is Antimicrobial Testing important for Coating products?
Antimicrobial testing of coating products is important as it ensures that these coatings are effective in inhibiting the growth of microorganisms (bacteria, fungi and mold) that may be harmful. Testing ensures that the paints and coatings used are capable of maintaining hygienic surfaces and are uninhabitable to microbial contamination. Testing also helps prolong the life span of the product as it ensures that microbial degradation is minimized. Additionally, antimicrobial testing of paints and coatings verifies compliance with industry standards, ensuring that the product meets regulatory requirements before being marketed.
