Permabond UV643 is an ultra-fast, UV curing adhesive which is ideal for bonding dissimilar surfaces such as plastic to metal or plastic to glass. Curing to a tack free finish, Permabond UV643 was developed for fast bonding of rigid plastics and is suitable for several thermoplastics including polycarbonate, PMMA PETG, PET, and ABS.
Permabond UV643: Cure in Seconds
A key feature of UV643 is the incredibly fast cure speed. Bonding glass to glass takes a fraction of a second when using a high intensity UV lamp. Even when curing through thick, UV stabilised plastic or at a lower powered lamp, UV643 still cures quickly.
Clean, professional, tack free finish
UV643 is a thixotropic adhesive with controlled flow properties for easy dispensing and precise application. With outstanding environmental and outdoor durability, UV643 passes 85/85 testing. This adhesive is highly resistant to heat, moisture, and humidity, making it ideal for automotive applications. Permabond UV643 has great versatility, with some of the possible applications including: PCB assemblies, automotive lighting, household appliances, optical assemblies, and plastic window and display bonding. UV643 is also suitable for coating and encapsulation applications.
