Adhesives Technology Review
ADVANTAGES AND BARRIERS FOR SOLVENT-FREE ADHESIVES
Advantages and barriers for solvent-free adhesives have been identified throughout the literature. The summary below is based upon much of the information available for review.Advantages
In general, the use of alternative solvent-free adhesive technologies appears to provide several advantages over solvent-based adhesives.
- Increased quality control.
- Reduced production costs. (Ref. 6)
- Lower insurance costs as a result of reduced risk. (Ref. 6)
- Lower permitting and disposal fees as a result of reduced hazardous waste generation.
- Reduced regulatory burden through elimination of stack and fugitive air emissions. (Ref. 14)
- Elimination of solvent capture and recovery, or incineration equipment. (Ref. 6)
- Avoided costs of emission control systems for solvent-based adhesive materials. (Ref. 6)
- Fewer Occupational Safety and Health Administration (OSHA) requirements for monitoring Volatile Organic Compound (VOC) concentration levels. (Ref. 14)
While solvent-free adhesives have cost, operational and environmental advantages, there are a number of financial and institutional barriers to widespread adoption.
- Inertia. Manufacturers may be reluctant to change long-standing work patterns or manufacturing inputs.
- Recycling Issues. For durable goods, excellent bonding properties may hinder recycling by interfering with product disassembly and removal of adhesive from raw material. (Ref. 1)
- Lack of Resources. Small businesses may not have the environmental or accounting personnel qualified to conduct total cost assessments that compare all costs and savings of adhesive alternatives.
- Workplace Risks. Occupational health and safety risks exist with regard to worker burns, especially with the use of high temperature cured adhesives and radiant curing equipment. (Ref. 15)
- Customer/Product Quality. The end product must meet all customer demands and retain the same level of quality that is associated with the product that uses the solvent-based adhesive; the transition should be seamless for the customer.
