ISO 9001 & 14001Customer service rep in USMoca is used as PU (polyurethane resin ) curing agant. The chlorine atoms on benzene ring can slow down the activity of "nh2" group, so as to extend the pot life while casting.Moca: Methylene-bis-ortho-chloroanilineMoca: Methylene bis ortho chloroaniline**************************************************************Moca (pellet):Appearance = light yellow granule (100% through 1/2 mesh serene)Specific gravity at 24 c = 1.44Specific gravity at 107 c = 1.26Melting point range = 110-120 cStorage stability = slightly hygroscopicSolubility = soluble in mek, dnf, tolueneAcetone, ethanol, insoluble in waterCuring agent for PU elasticity. Finished applications are:1. Caster: PU caster and wheels2. Seals: PU hydraulic seals and packages3. Spring: PU rod, sheet, bar and film4. Blade: PU drum blade for copier and laser printer5. Squeegees: PU squeegees for screen printing6. Friction wheels: PU disc and friction wheel for textile machine7. Roller: All kinds of ru rollers8. Parts: PU flexible coupling and partsMoca (liquid):Appearance = amber liquidBoiling point = 667 f ( 353 c ) (decomposes)Density (g/cc) at 68 f (20 c) = 1.21Density (g/cc) at 140 f (60 c) = 1.18Density (g/cc) at 212 f (100 c ) = 1.15Viscosity, cps at 68 f (20 c) = 690Viscosity, cps at 140 f (60 c) = 22Viscosity, cps at 212 f (100 c) = 55Moca-l300, being a liquid at room temperature result in significant processing advantages, for example, in such operation as transfer, melting down of solids is eliminated. Also, the possibility of freezing-up is no longer a concern during mixing or in meter mixing machines. Additionally, its liquid state permits processing prepolymer at lower temperatures than that of moca.Moca-l300 has an equivalent weight of 107 compared to 133.5 for moca. This means that about 20% less by weight is required for a given prepolymer at the same stoichiometry.Sample available via "freight collect"You can download catalogs and submit quote requests on our web site
