Product Highlights

2003NA is a single-component hot melt adhesive that cross-links through a chemical reaction with moisture found in the surrounding air and substrates. 2003NA is especially effective for automotive interior trim applications. Additionally, the intrinsic chemical nature of wood and wood products makes 2003 NA ideal for bonding soft woods, hard woods, particle board, MDF, papers and wood veneers. It bonds equally as well to EPS, PU foam, aluminium, steel, and various steel coatings, including epoxy/phenolic coatings, and various plastics, such as PP, PVC, ABS, and SMC.

Applications & Uses

Typical Application

Swift®therm 2003NA is used in lamination and assembly applications in the automotive industry, industrial assembly, panel lamination, woodworking, and furniture production.

Instructions for Use
  • Application temperature: 280°F - 350°F.
  • The structure of the substrates and working conditions will influence adhesive bonding. Adhesive trials with substrates under customer conditions are necessary. Due to the high softening point and melting temperature quick melting and application of adhesive is recommended. Avoiding too long heat exposure of adhesive in the pre-melter prevents from thermal degradation and decreasing of bonding quality.
  • Remarks: Prolonged exposure to high temperature should be avoided since this may be lower the bonding performance. Usually, this adhesive is not suitable for plastics containing monomeric plasticizers: plasticizer migration can cause degradation of the adhesive film. Applications like this have to be tested for compatibility.
  • Cleaning instructions: While the product is hot a preliminary cleaning should be done by scraping with a spatula.
