Molecular sieve IG 3A Molecular Sieve IG 3A is an alkali metal aluminosilicate; It is the potassium form of the type A crystal structure. It has an effective pore opening of about 3 angstroms (0. 3nm) . It adsorbs molecules with effective diameters smaller than approximately 3 angstroms. But excludes molecules any larger than that. This insulating glass desiccant can deeply co-adsorb the resident moisture and organics in Insulating Glass, keep the IG clear and transparent even at very low temperature. More important, it can successfully avoid the tremendous air pressure unbalancely placed on the glasses, which was superposed by seasons of day night temperature changing and the ensuing air desorption and adsorption function of common IG desiccant. Thus it resolves the problems of windows distortion caused by IG inflation and shrink, expanded the life span of IG windows.

  Application: automotive exhaust gas,griculture, metallurgy, petrochemical industry, glass, ceramics and electric light industry, high and new technology industry.. Brief introduction     The rare-earth elements (REE) are the elements Sc (scandium) Y (yttrium) and the 15 lanthanide elements with atomic numbers 57 through 71, namely, La (lanthanum), Ce (cerium), Pr (praseodymium), Nd (neodymium), Pm (promethium), Sm (samarium), Eu (europium), Gd (gadolinium), Tb (terbium), Dy (dysprosium), Ho (holmium), Er (erbium), Tm (thulium), Yb (ytterbium), and Lu (lutetium).    . The application of rare-earth      In the traditional industrial field, rare-earth is mainly used in agriculture, metallurgy, petrochemical industry, glass, ceramics and electric light industry. With the research of rare-earth developing, (With the development of the research of rare-earth), rare-earth is gradually applied in high and new technology industry, used as lumi

Catalyst AD75 was developed to meet the printing industry requirements of a low odor / lowcolor adhesion promoter.Catalyst AD75 is used as an adhesion promoter in solvent based printing ink withnitrocellulose / polyurethane or nitro cellulose / polyamide resin system.Catalyst AD75 performs the critical role of bond formation between the ink resin and filmsurface .The use of catalyst 100 also provides the printed substance with increased watergrease and heat resistance with no odor and reduced yellowing effect.

inks series are a range of rotogravure inks has been specifically formulated from high quality raw materials for surface and reverse printing on PVC films and shrink PVC. inks are available in white and wide range of colors.
