چکیده
This paper will highlight various methods utilized for cnvironmcntal compliance with solvent coating and laminating applications. Discussion will summarize the recovery and oxidation alternatives, including a brief overview of thc advantages and disadvantages. The paper concludes by focussing on more specific examples of solutions, including capture hooding and enclosures, dryer air flow schemes, thermal oxidation integration, and use of secondary heat rccovcry for return energy to the drying process.

Solventless coating for Tablets: An alternative to conventional coating technique
There are many ways to coat tablets. Coatings are a very important part in the formulation of pharmaceutical dosage form to achieve excellent formulation quality (e.g., color, texture, mouth feel, and taste masking), physical and chemical protection for the drugs in the dosage forms, and modification of drug release characteristics. Most film coatings are applied as aqueous or organic-based pol...
متن کاملA Matrix Evaluation Model for Sustainability Assessment of Manufacturing Technologies
Technology assessment is a vital part of decision process in manufacturing, particularly for decisions on selection of new sustainable manufacturing processes. To assess these processes, a matrix approach is introduced and sustainability assessment models are developed. Case studies show that the matrix-based approach provides a flexible and practical way for sustainability evaluation of new ma...
متن کاملSoftbake of Photoresist Films
After coating, the resist film contains a remaining solvent concentration depending on the resist, the solvent, the resist film thickness and the resist coating technique. The softbake reduces the remaining solvent content in order to: avoid mask contamination and/or sticking to the mask, prevent popping or foaming of the resist by N2 created during exposure, improve resist adhesion to the subs...
متن کاملCore-shell polymeric microcapsules with superior thermal and solvent stability.
A protective polydopamine (PDA) coating is applied to core-shell microcapsule surfaces by the polymerization of dopamine monomers. A neutral aqueous solution and the addition of an oxidant (i.e., ammonium persulfate) are crucial for microcapsule survival and the initiation of PDA polymerization, respectively. The resulting PDA coating is a dense and uniform layer approximately 50 nm thick. The ...
متن کاملReview of glycol ether and glycol ether ester solvents used in the coating industry.
Ethylene oxide-based glycol ether and glycol ether ester solvents have been used in the coatings industry for the past fifty years. Because of their excellent performance properties (evaporation rate, blush resistance, flow-out and leveling properties, solubility for coating resins, solvent activity, mild odor, good coupling ability, good solvent release) a complete line of ethylene oxide-based...
