Perrin, et al [30], who related the loss of gloss with the increase of the surface roughening for the coating systems.
Unfortunately, the chemistry of silicone alkyds precludes adequate long-term performance on the exterior of Navy surface ships, which is evident by their loss of gloss and color fading to a light gray color within 9 to 12 months after application.
Their broad scope of performance enhancement ranges from adding protective effects such as improving heat, light and weather resistance to reduce color fading and loss of gloss, to flame retardants with a preferred environmental and health profile for intumescent coatings, processing waxes lending functional end-application benefits and specialty ingredients such as APEO-free wetting agents, label-free dispersing agents, sugar-based neutralizing agents, as well as silver biocides for antimicrobial preservation.
ASA polymers possess inherent UV resistance, that when colored with light-stable pigments ASAs achieve long-term outdoor color retention without the need to paint, whereas similar pre-colored polymers such as ABS, HIPS (high impact polystyrene), or PVC (polyvinyl chloride) are more susceptible to dramatic color shifts accompanied by degradation and loss of gloss and other properties upon long-term UV exposures.
After eight years of service, a recent inspection revealed that the coating retains an excellent appearance with no fading or loss of gloss.
Other methods can be used to assess the effects of scrub testing, such as loss of gloss.
Loss of gloss and thin corners due to poor extensibility of the melt also put limits on reducing melt temperature.
This high angle, indirect gloss measure will be most sensitive to the initial loss of gloss in very glossy samples.
The tests typically consist of the application of a complex scratch pattern followed by measurement of the loss of gloss of the damaged area (1, 2).
Water-borne epoxy limitations include loss of gloss on exterior exposure; fair exterior color stability; minimum application temperature: 50 [degrees] F; two component system; and limited pot life.
To avoid wrinkling, fading, or loss of gloss in solvent-thinned paints and streaking of latex paints, apply after morning dew dries and stop at least 2 hours before evening damp.
