UV curable polymer can be removed by
most solvents
One component, flexible, ultraviolet-curable polymer system for bonding, sealing and coating can be removed by most conventional solvents and does not contain any solvents or other volatiles.
Master Bond has developed a one component, flexible, ultraviolet-curable polymer system called UV14-3 for bonding, sealing and coating, and which can be removed by most conventional solvents It is a 100% reactive, moderate viscosity liquid at ambient temperatures which does not contain any solvents or other volatiles

The epoxy resin provides high physical strength properties, adhesion and resistance to solvents, water and alkalis.
Epoxy-resin system resists high temperatures
Cures to a tough, strong solid with excellent long term durability and chemical resistance even when exposed to adverse environmental conditions.
When exposed to a UV light source, it cures as a durable, tough, non-yellowing system which can be used as an adhesive, sealant and coating.
It also possesses electrical insulation properties.
Maximum absorption of UV energy takes place in the 250-365nm range.
The cured coatings, adhesives and sealants can be used over the temperature range of -50 to +120C.
It is not oxygen inhibited and exhibits a desirably fast curing rate at ambient temperatures even in the presence of air.
The system can be cured in section thickness up to 0.3cm deep, making it suitable for electronic and opto-electronic potting and encapsulation applications.
This performance is due to its catalyst system.
It imparts vibration and shock resistance as well as ability to withstand thermal cycling and thermal shock.
It is readily attacked by most solvents, such as acetone, xylene and MEK, making it suitable when the UV system must be easily removed.
Curing time depends on the type of UV lamp, distance of the lamp from the surface of the UV14-3 and thickness of the section to be used.
Typical cure medium-pressure mercury vapour lamps are recommended.
No solvents or other volatiles are released during the curing process.
The storage stability is six months at room temperature in the original, unopened containers. Request a free brochure from Master Bond ...
