LOCTITE 420 Quick-drying Adhesive for high and low temperature resistant metal plastics for general purpose
LOCTITE 420 is a clear, colorless, all-purpose adhesive containing ethyl capillarity. Applicable to metals, rubber and plastics, Primer LOCTITE SF 770 or LOCTITE SF 7239 can also be used in combination with polyolefin. The initial fixation time is 5-20 seconds.
1. Fast curing between two surfaces
2. Ideal products for bonding small and medium sized parts
3. It has good adhesion to most substrates
4. Suitable for metal, rubber and plastic
5. The initial fixation time is 5-20 seconds
7. No solvent
- Global Tab
420 is tested to the lot requirements of Military Specification Mil-A-46050C. Note: This is a regional approval. Please contact your local Technical Service Center for more information and clarification. Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Thin bond
lines result in high cure speeds, increasing the bond gap will
decrease the rate of cure.
Cure Speed vs. Humidity
The rate of cure will depend on the ambient relative humidity.
