They reduce the risk of contamination even when used on rough surfaces and can be used for pre-cleaning, degreasing, solvent wiping
and excess sealant removal.
A lower-cost Alternative to reusable rags, these wipes can be used for overall general cleaning, post-paint stripping and wiping, water-rinse drying, solvent wiping
, excess sealant removal, oil and grease cleaning, and tool wiping.
In addition, ASTM D 7334 can be used in the analysis of substrates, particularly plastics, before and after cleaning or solvent wiping
to measure the effectiveness of these processes.
The simple conclusions are that solvent wiping
only or use of grit blasting without a primer do not provide any real environmental resistance, while Metal Jacket provides environmental resistance at a level beyond the power of this test length to really impact.
Solvent wiping of the TPO substrates with isopropyl alcohol followed by xylenes prior to coating with CPO increased the mean roughness of the TPO surface by more than 100 nm; but it had a much larger effect on the roughness of the (several micrometers) CPO-TPO interface after coating.

One of the most interesting variables that we investigated is the influence of solvent wiping, with xylenes and isopropyl alcohol as the wiping solvents, on the CPO/TPO interface in the coated substrate.
A significant challenge was the development of a mold release that allowed good paint adhesion without the need for scuff sanding or solvent wiping
uses a terpene, petroleum, or chlorinated solvent applied to an absorbent material.
Plastics must have mold release agents and other contaminants removed and may need power washing and solvent wiping
to accomplish satisfactory preparation.
(isopropanol, IPA/water or naphtha) of the sanded or wiped surface before the coating is applied usually prevents this type of telegraphing.
Surface treatments for elastomers range from solvent wiping
, to mechanical abrasion, to chemical modification.
