Paint & Coating Evaluation Test


The use of paints, varnishes, and coatings has seen an unprecedented increase in recent decades, courtesy of the technological advances made in the realm of paints and coatings products. The tremendous increase in the use of such products has been due to their widespread applications, from cars, houses, various electrical and electronic items, various infrastructural units, military equipments, to almost every usable item. The materials on which paints and coatings can be applied include metals, plastics, civil materials etc.

The main advantage offered by paints and coatings is the fact that they prolong the useful service life of the items that they are applied on, besides ameliorating the aesthetic appeal of the item. They do so by providing protection to the items against corrosion, abrasion, extreme temperatures, harmful chemicals, moisture, UV rays and all the detrimental conditions that the items are exposed to. Various tests that have been formulated by a number of national and international standards check for the performance characteristics like stability, durability, and resistance to failure tests. Besides, there are a number of noted ‘Environmental Regulations’ related to the composition of such products. For example, paints contain the harmful Volatile organic compounds which have to be tested.

Modi Laboratary is very much competent to conduct standardized and customized tests on various types of Paints & Coatings, aided by its well trained staff and the latest equipments at its disposal.

MODI LABORATARY  Lab helps answer difficult questions such as:

•    Why is my coatings product losing adhesion?
•    What is causing blisters or bubbles to form in my applied coating?
•    How stain-resistant is my paint product?

Physical testing capabilities of MODI LABORATARY  include

•    Application Properties
•    Liquid Coating Properties
•    Film Appearance
•    Coatings Performance

MODI LABORATARY  has also developed expertise in testing of Volatile Organic Compounds (VOC) by EPA Test Method 24. We have successfully measured VOCs in paints and coatings for both manufacturers and end users.

Testing for Aesthetic Appeal

Applied coatings’ appearance properties may be evaluated for their aesthetic or visual characteristics. These may include:
•    Reflectance
•    Yellowing of other discoloration
•    Hiding power
•    Dry film thickness (DFT)
•    Dry hiding (from porosity)
•    Gloss (20, 60, 85 degrees)
•    Opacity, intrinsic (contrast ratio, scattering coefficient)
•    Opacity, applied (brush, roll, spray)

Performance of Coatings

Many manufacturers have turned to MODI LABORATARY  to learn how their products will perform over time and under different environmental conditions. MODI LABORATARY  has developed expertise in examining a wide range of Film performance properties including:
•    Hardness
