The ARALDITE® 2028-1 adhesive forms transparent bonds capable of withstanding harsh conditions.
The adhesive provides robust resistance against hot, humid, and dusty outdoor conditions, making it particularly suitable for traffic light housings, digital signage, LED bonding, and potting applications. This UV-stable adhesive maintains its transparency without yellowing, even after prolonged exposure to thousands of hours of light.
Utilizing the uniquely non-CMR (Carcinogenic, Mutagenic, or Reprotoxic) polyurethane adhesive, ARALDITE® 2028-1 establishes a safer work environment and reduces the need for extensive safety measures.
The automated application of this non-foaming and user-friendly adhesive facilitates faster production cycles, ensuring durable and realible results over time.
