UV Light Curing Adhesives
for Electronics Assembly
Strain Relief, Component Tacking and Heat Dissipation
- Fast "instant" cures
- Single part formulations
- Cure on demand - only upon exposure to light
- Excellent adhesion
- Precise and easy dispensing
- Room temperature storage - unlimited pot life
Description
Achieve increased productivity over epoxies, silicones and hot melts with
easy to use, low cost adhesives. DYMAX UV adhesives cure
in seconds. The "on demand" cure feature of these resins means
no rework as a result of adhesive migrating onto solder pads or through
holes. DYMAX adhesives are ideal for bonding heat sinks
and heat sensitive components, wire and component tacking, strain relief
of large parts and securing hand inserted components prior to wave soldering.
