Brushes for water-based adhesives: precision and compatibility for leather bonding

Manual or guided adhesive application in the leather industry requires a reliable, durable and precise tool. Keck Chimie recommends the use of industrial brushes featuring: 

• Synthetic PBT fibers (polybutylene terephthalate)
• High chemical resistance, even in prolonged contact with water-based adhesives
• Low absorption: prevents product loss and ensures even application

PBT is known for its thermal stability, controlled flexibility and proven compatibility with industrial water-based adhesives. 

Using a standard brush that is not compatible with your adhesives can lead to: 

• Alteration of the adhesive’s viscosity
• Imprecise or uneven application to substrates (leather, soles, textiles, etc.)
• Chemical contamination of the product

By choosing brushes tested for chemical compatibility with Keck Chimie’s water-based adhesives, you minimize risks and optimize your production yield.

Keck brushes made of PBT synthetic fibers – sizes 192/4 to 192/20 – ensuring an even application of water-based adhesives on leather, soles and textiles. 

These brushes are ideally suited for bonding in the following trades: 

• Technical footwear assembly
• Leather goods manufacturing
• Production of flexible and coated items

They are: 

• Available in different formats (flat, beveled, fine brushes), from model 192/4 (very fine) to 192/20 (wide width), to suit a variety of requirements in terms of precision or application surface
• Easy to handle, even at high production speeds
• Tested for optimal compatibility with Keck Chimie’s water-based adhesives

Keck Chimie’s technical teams support you in selecting the right brush for your bonding process and water-based adhesive formulation.
