Corrosion Inhibitors for Coatings: Main Types & Selection Tips
Talc, usually classed as an "extender" rather than a primary pigment, is also commonly found in anticorrosive paints because it is both highly inert and has a lamellar form. MIO is a highly effective anticorrosive pigment. There is currently a trend to blend this material with non-lamellar MIO which can be readily obtained for a tenth of the price.

Compounding of Polypropylene
Typical additives to unmodified PP include antacids such as calcium stearate, calcium pelargonate, zinc oxide or hydrocalcite. These compounds are required to neutralize catalyst residues that could otherwise form acids detrimental to the converter's equipment. The second basic additive to PP is antioxidant.
Talc as Reinforcing Filler in Polypropylene Compounds: …
Talc has a positive effect on the stiffness but a deleterious effect on the tensile strength and ductility; 4. Plately fillers such as talc are likely to suffer more severely from the effect of stress concentration. As results, the impact strength and the resistance of crack propagation were decreased; 5.
MICRONIZED TALC: A COST-EFFECTIVE FUNCTIONAL …
talc grades suitable for PP nucleation and the most common one is talc HTP1, characterized both by a very fine particle size distribution (D 50 1.9 µm) and by a high degree of pureness. Micronized talc reduces the degree of supercooling in the resins by increasing the onset of the crystallization
Anti-block Additives
different mechanisms compared to the inorganic anti-blocking additives, migrat-ing to the film surface upon cooling and forming a release layer. Sometimes combinations of inorganic and organic anti-blocking additives are used. Organic additives typically have lower anti-blocking ability in comparison to the inor-ganic ones but better slip effect.
Talc as Reinforcing Filler in Polypropylene Compounds: …
At low concentrations (less than 3 weight%), talc acts as a nucleating agent, reducing spherulite size and shortening processing time [ 7 ]. At higher loadings (10-40 …

New additive technology provides scratch resistance
The new additive yields a permanent scratch resistance and no fogging or gloss change is observed because the additive does not migrate. In addition, it does not have any negative effect on the odour of the compound, which is particularly important to pass smell tests undertaken by car manufacturers. Table 1.
Polypropylene
Polypropylene is a nonpolar, chemically inert material and cannot be welded using the high frequency equipment that is commonly used for flexible PVC. However, thermal bonding techniques work well. In some fields, polypropylene moldings and thick sheets are welded by using hot gas, hot plate, or friction techniques.
