Product name:Spermidine Other name:N-(3-Aminopropyl)-1,4-butanediamine;Spermidin , eN-(3-Aminopropyl)-1,4- butanediamine;4-azaocta , methylenediamine CAS Number:124-20-9 Molecular formula:C7H22N3 Molecular weight:148.29 Purity:20% with 80% silicon oxygen Appearance:White crystalline powder Packing:1 kg/bag & 25kg/drum Application:Dietary supplement material 3Product introduction Spermidine, a low molecular weight aliphatic carbide containing 3 amine groups, is one of the natural polyamines present in all living organisms. One of the important raw materials for drug synthesis is widely used in the synthesis of pharmaceutical intermediates. Spermidine maintains cell membrane stability, increases antioxidant enzyme activity, and improves photosystem II (PSII) and related gene expression. Spermidine also significantly reduced H2O2 and O2.- levels. Spermidine is a precursor of spermidine, derived from putrescine, which promotes the structural stability of cell membranes and nucleic acids. Spermidine has a variety of amazing effects, including but not limited to regulating circadian rhythm, improving hypertension, protecting cardiovascular, preventing Alzheimer's, boosting immunity, fighting cancer and even anti-aging. 4Feature Spermidine is a naturally occurring polyamine compound commonly found in food. It is essential for cell growth and survival. Spermidine maintains cell membrane stability, increases antioxidant enzyme activity, and improves photosystem II (PSII) and related gene expression. Spermidine also significantly reduced H2O2 and O2.- levels. Colorless transparent liquid, soluble in water, alcohol and ether; It is hygroscopic. Solid powder can be used in variety formulations. 5Applications Spermidine is involved in many biological processes in vivo, such as regulating cell proliferation, cell aging, organ development, immunity, cancer and other physiological and pathological processes. Recent studies have shown that spermidine plays an important role in regulating synaptic plasticity, oxidative stress and autophagy in the nervous system. Spermidine can slow protein aging. Because different molecular weight proteins may play different roles in the aging process, some large molecular weight proteins may play a key role in controlling the aging process of leaves. Once these proteins begin to degrade, aging is inevitable, and controlling the degradation of these proteins can delay the aging process.

Strong bonding strength and good initial bonding power; water-proof and ageing resistant. Easy application. It is easy to apply the adhesive evenly on the bonding surface and no adhesive legging occurs. Application for use 1,Surface preparation: the grease, dust, moisture, rust on the bonding surface must be cleaned off. Make sure that the surface must be dry during rainy days, or it will cause non-stick atmosphere. 2, Pour adhesive on the two bonding surface separeately and spread it with brush or scraper. To achieve the best bonding performance, the application should be done toward the same direction and evenly. 3.the adhesive should be applied evenly and not too thick to avoid the weakening of the bonding strength. But for porous materials or materials with coarse surface, you can apply more accordingly. 4,After application of the adhesive, enough time should be given to let the solvent evaporate completely to avoid bubble or stickiness. The airing time is about 5 -8 minutes/25C and varies from the temperature, humidity and adhesive film. The bonding can be done after the surface is dry by touch. For porous materials, you can bond directly after application of the adhesive. 5,The application should be done once and for all. Aim the two surfaces, bond together and press. Don’t move the bonding surfaces back and forth, or the bonding effect will be affected.
