Quick Details

Use: Suitable for aqueous, oily and various types of base materials to produce non (low)-toxic antirust paint, primer and integrated antirust paint. This product can completely or partly replace red lead antirust pigment.


1. Compared with other antirust paint, it has significantly improved dispersion property, stability, anti-sinking property and antirust performance.

2. 808 composite antirust pigment has obvious price advantage compared with other antirust pigments due to its low base material price.

3. Compared with red lead, 808 composite antirust pigment has much lower heavy metal content and is a new environmentfriendly product. It is easy to use by spraying or brushing, and is an ideal new antirust product to replace red lead.

Q:what are the three major photosythetic pigments?
three major pigments are 1.chlorophyll a 2.chlorophyll b 3.carotenoids chlorophyll a is the major pigment,chlorophyll b n carotenoid are the accessory pigments which help in absorption of the incident light of different wavelengths. another pigment xanthopyll-fucoxanthin is also present in some plants
Q:why do plants need more than one pigment for light absorption?
Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.
Q:What exactly are eyeshadow pigments?
Q:How many pigments does grass reflect?
Pigments are the colors that make grass look green. They are the pigments that do photosynthesis. Grass looks green because it reflects green light. It reflects the wavelengths of light that have the frequency of green light. Grass has other pigments that we do not see through the chlorophyll, but it is the light that is reflected.
Q:explain an absorption spectrum of different pigments and the action spectrum of?
A pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) The familiar colors of the rainbow in the spectrum include all those colors that can be produced by visible light of a single wavelength only, the pure spectral or monochromatic colors.
Q:How do scientists use a spectrophotometer to detemine the absortion spectrum of a pigment?
A pigment molecule absorbs at specific wavelength(s), meaning that when light of a specific wavelength is incident to the molecule only certain wavelengths are absorbed while others are transmitted. The spectrophotometer emits monochromatic light (light of only one wavelength) which passes through the pigment molecule and a detector determines the amount of light that is either absorbed or transmitted by the sample. This is done at wavelengths from the UV (180-330 nm) to the visible (330-700 nm) and the light that is either transmitted or absorbed is detected by the spectrophotometer and is able to be graphed with absorbance representing the y-axis and wavelength representing the x-axis. The resultant graph will depict the absorption spectrum of that particular pigment molecule. Hope that helps.
Q:7th grade biology/botany. Leaves + color Pigments + HELP!!!!! + Please!!!?
Chlorophyll leaves and Tannin enters,depends on the temperature and seasons
Q:How do you make paint pigments?
Pigments are specific minerals found in rocks. Then they are ground down and mixed with the binders for oil, acrylic, and watercolor paints. You can take art classes that teach you how to make your own paints. I have a cousin who hikes to find her own pigments and makes all the colors she paint with. If you'd like something less labor-intensive, you can buy the pigments you want from lots of art stores these days. They can be added to pre-existing colors to enhance them, or you can start from scratch to formulate your own colors. The bottles i've seen are around 8 ounces, and cost about $50. You will likely find books in the library and articles online that will help you learn to make your own pigments.
Q:do all leaves extract contain the same pigments??why?
Plants Plants have classes of pigments that act as adjuncts to the chloroplast's chlorophyll, in several ways. Some are accessory pigments that broaden the range of absorbed light. These pigments are found in the light gathering arrays in chloroplasts. They also alter the color of the leaf depending on what specific pigments it has to gather light energy and that determines what is reflected (green is the basic reflected spectra but is might be yellowish or bluish green). The major accessory class of pigments, the carotenoids, collect light in the red to yellow wavelengths chlorophyll a can’t, then the carotenoids transfer the energy to chlorophyll a to process. Among the carotenoids are the xanthophylls that provide UV protection for the light gathering centers of the chloroplast. Plants adapt to situations and some just have fewer chloroplasts so have less chlorophyll and absorb less of the light. In low light situations they need fewer so variegated plants are possible. This reduced chlorophyll level allows small amounts of other pigments like the yellow pigment xanthophyll to show up.
Q:Can someone describe the role of accessory pigments in photosynthesis?
