Levels of gloss

It may be that a component must appear to be the same colour as, or match, one or more other items—in which case assessments of the precise colour and the appropriate level of gloss will be important. 

Use with high speed maintenance programs where extremely high levels of gloss and appearance are desired. Can be burnished daily or on an intermittent schedule without producing excessive amounts of dust. Exceptional application and lay-down characteristics. With these maintenance procedures a consistent high level of appearance can be sustained over an extended period of time.

The determining factor in how deep a thread can be stripped is its strain rate. For the sake of this bottle cap example, it will be presumed that it must be made of acrylic for appearance reasons because this polymer can provide a very high level of gloss. Acrylic is an amorphous thermoplastic with a very low rate of strain. In this case, too low to permit the part to be stripped off the mold. Therefore, the cap would need to be turned off the core of the mold. 

Blanc fixe and finely ground barite are also used as extenders for water-based paints, particularly in wood paints requiring a high level of gloss and minimum color distortion. The high refractive index of these materials allow them to function as a translucent white pigment in latex paints, providing a... 

The level of moisture ia the furnace atmosphere is also of importance ia the development of good fired surface appearance. The range of moisture normally associated with good enameling practice is 1—2 vol % of moisture (21). Levels below 1 vol % may result ia reduced gloss of the glass surface levels above 2 vol % may result ia blistering or a scummy surface. Wiater conditions usually cause dry furnace atmospheres, and summer conditions may result ia excessive moisture if the furnace is not properly vented. 

The thermal and UV resistance will depend on the stabiliser systems used. The hardness of the coating will depend on the amount and type of plasticiser used. Correct selection of the plasticiser can permit the use of the plastisols at high or low temperatures, provide fire resistance or oil resistance. Plastisols can be produced in a range of gloss levels from 80 units down to 10 gloss units. 

Once your problem takes on a 13 C dimension, you are of course, obligated to examine the 13 C data with the same level of dispassionate scrutiny that you apply to the proton data. Chemical shifts cannot be fudged and unexpected peaks cannot be glossed over. You have to be able to account for everything you see to have confidence in your product. 

The gloss and haze levels measured by Chung et al. [81] correlated very well with the applied stress in the shear refiner experiments. For these experiments the haze decreased and gloss Increased nearly linearly with the applied shear stress, as shown in Fig. 8.39. Thus, application of a shear stress of about 200 kPa to a 2 dg/min MI LDPE resin can improve the haze and gloss levels of the product film. The shear stress for the shear refiner was calculated using Eqs. 8.10 and 8.11. 

Addition of a finely divided filler, such as silica, silicate or alu-minate has been demonstrated to reduce the gloss of thermoplastic molding compositions yet this is often accompanied by an undesirable reduction in the level of at least some physical and/or mechanical properties of the molded article.
