How to use
For best performance bond surfaces should be clean and free from grease.
The product should be dispensed using black feed lines. Cooling should be provided for temperature-sensitive substrates such as thermoplastics. Plastic grades should be evaluated for the risk of stress cracking when exposed to liquid adhesive. Excess adhesive may be removed using an organic solvent. Bonded assemblies should be allowed to cool before being subjected to any service loads.
Cure rate is dependent on lamp intensity, distance from light source, depth of cure needed or bondline gap and light transmission of the substrate through which the radiation must pass.
This product is light-sensitive; exposure to daylight, UV light, and artificial lighting should be kept to a minimum during storage and handling.
FAQ
Yes, for best performance, bond surfaces should be clean and free from grease.
