RUST PROTECTION SPECIFICATIONS: MEGAFLEX
PRODUCT
DESCRIPTION
:
Product shall be acrylic, abrasion resistant, rust preventive
coating.
Coating must be one part acrylic base self priming, thixotropic
semi-paste coating that contains at least 36% highly elastic in
water dispersed polymers.
V.O.C. (volatile Organic Compound) shall be 0.01 or less as
evidenced by OSHA Form 174 MSDS.
Coating cannot contain any lead, organic solvents, or
bitumastic materials or other hazardous ingredients as
evidenced by OSHA Form 174.
Coating shall be 100% waterproof.
Coating must be 100% ultraviolet resistant so as not to
breakdown as a result of long term exposure to sunlight.
Coating must be capable of 200% elongation so as to
completely prevent cracking due to expansion and contraction
as well as dimpling resulting from impacts.
Coating must afford excellent chemical resistance to acids
alkalis, salts and fuels.
Coating must be self-extinguishing.
Coating must dry to a smooth texture.
Coating dry film thickness shall be 14 mil.
Coating samples wet and dry shall be submitted for evaluation
at the time of the bid if supplying an alternate product.
