FREQUENTLY ASKED QUESTIONS ON INVESIL
Who has developed INVESIL coating?
INVESIL coating was world’s first commercial antimicrobial coating and incepted in 2007 by a renowned coating scientist Dr. Atul Tiwari who has also published more than 20 books along with the first handbook on antimicrobial coatings.
What is the appearance of INVESIL coating?

I see you suggest the best results for applying are by using a LVLP spray gun. But if we were to have this done wipe wipes what are your suggestions on the application process? Applying in a circular motion, applying in a straight line all in the same direction, or applying it horizontally then vertically?
As the number of application area are significantly large, we, therefore suggest customers to develop their own application method conducive to their substrates.
Will putting anything coated under a heat lamp cure the coatings faster?
Yes, INVESIL curing can be accelerated at higher heat or temperature.
If applied to concrete will it prevent spray paint from bonding or allow simple wash off with a sponge, soap, and water? Or would a power washing remove it?
It will certainly help in easy removal of the paint. However, our other product AVIRAL more suitable for such application.
When applied to metal, painted surface or fiberglass does it have a glossy or matt finish?
Depending on the surface, INVESIL could enhance the gloss. INVESIL for matt finish is also available.
