Artists are surprised to see one application of paint barely hide and another completely cover all that is underneath. Some wonder why they begin to see drawings underneath paint that before were completely unnoticed. Other artists apply a glaze are frustrated when it covers the paint below. These are common problems experienced by all painters at one time or another, but the reasons are ...

Since reducing particle size will reduce flatting efficiency, it is only natural to assume that it will benefit gloss. The particle size of the pigments in a coating will have an effect on film smoothness and cause scattering of light (Fig. 3).
TiO2 will reduce the thermal stability of polyesters and polycarbonates, while iron salts will do the same for PVC. Improper TiO2 selection reduces the UV stability of polyethylene. Likewise, the reactivity of a polymer end group can alter the chemistry of certain colorants and lead to a color change.

Jul 10, 2017· Most of the addition polymers (PE, PP, PS, PVC) don''t absorb moisture, but their additives, like fillers and pigments, might. In such cases, anything over around % H2O by weight will boil off as it leaves the die and create dotted lines or bubbles on the extruded surface.
When added to polyester or epoxy resins, fillers can dramatically change the properties of the final product. Use CabOSil or ViscoFill to thicken, Microspheres to reduce weight, Talc for low cost, and Glass Fibers for reinforcements.

Aug 23, 2013· Types of polymers degradation. The degradation of polymers usually starts at the outer surface and penetrates gradually into the bulk of the material Blaga ().Polymer degradation can be caused by heat (thermal degradation), light (photodegradation), ionizing radiation (radio degradation), mechanical action, or by fungi, bacteria, yeasts, algae, and their enzymes (biodegradation).

Material Properties of Plastics Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions. Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymerization (polycondensation) [1] (Figure )..
applicative use. Organic yellow pigments have greater transparency than inorganics, yet are susceptible to fading in outdoor applications. RED Red iron oxides, Fe 2 O 3, are an inorganic red pigments that gives the familiar red barn color. Iron oxide reds are thermally stable and have relatively low cost. Their particle size can be optimized

Apr 15, 2008· Particle size of pigment particles in paint is a critical parameter that affects surface finish. The difference between flat, eggshell, semigloss, and gloss finishes is determined by the PSD of the pigment particles. Accurate monitoring of the particle size is an important parameter to .
Cryogrind was established in 1981 to commercialise Cryogenic processing technology which utilises liquid Nitrogen to freeze and grind soft or temperature sensitive rubbers and plastics. In the late 1980''s the company was able to adapt this technology to the recycling of rigid and flexible PVC.
The application of aluminum pigments in plastics presented a problem in the past because of the flow lines which they caused in injection molded parts. By using large size aluminum pigments, with an average particle size of 60 μm to 330 μm and larger, it is possible to avoid these flow lines and produce metallic looking plastic parts.
