BINDER MODIFIER MW1010 LAMINATION AID |
View the Material Safety Data Sheet (MSDS) for product MW1010
Binder Modifier MW1010 Lamination Aid:
MW1010 is a specialty non-hazardous resin additive which increases the ability to laminate polyvinyl butyral (PVB) based tape casting binders. PVB tapes traditionally do not tack to themselves easily under mild conditions such as those in the tacking operation of multilayer bar building. The use of MW1010 increases the ability to stick layers to themselves very quickly and under mild conditions of heat and pressure making it ideal for bar building in the manufacture of multilayer ceramic components. Testing of MW1010 modified PVB tapes have shown even better tacking performance than acrylic tape casting binders which have traditionally worked better than unmodified PVB tapes.
It is believed MW1010 works by reducing ceramic-PVB interactions which can act as weak crosslinks. These interactions would be expected to slow lamination by restraining polymer chain movement. Another expected benefit of reduced ceramic PVB interaction is reduced slurry viscosity aging especially with boron containing ceramics. Compared to other additives to improve tackiness such as plasticizers, MW1010 has little effect on other tape properties.
A representative formula as used for extremely fast tacking tape is given below. The binder in this formula is a commercially available formulated PVB system. For minimal effect on other tape properties the MW1010 should be used to replace an equivalent amount of organic tape solids. Therefore the ceramic loading of the tape is kept constant. As the MW1010 resin replaces a portion of the binder solids it is a cost effective measure in addition to the performance increase expected. The formula yields a finished tape which is calculated to give about 56% volume loading of ceramic in the green tape. The use of extra toluene was to give a lower viscosity of about 350 cps and is not necessary if a higher viscosity can be tolerated. Other than possible changes in tape tacking, normal slurry milling, casting, and tape processing should be adequate.
