- Cleaning Information
- It is important to remove excess adhesive from the substrate before it is cured.
- Solvent cleaners such as alcohol or acetone yield good results.
- Once the adhesive has cured it will bevery difficult to remove and may require as much as 350° F to soften to allow removal.
- Mixing
- It is highly recommended that either meter mix equipment or cartridges with static mix nozzles be used toproperly ratio and dispense the adhesive.
- For hand mixing, combine Part A and Part B in the correct ratioand mix thoroughly.
- Heat buildup during and after mixing is normal.
- To reduce the likelihood of exothermic reaction or excessive heat buildup, mix less than 100 grams at a time.
- Mixing smaller amounts will minimize heat buildup.
- Bonding
- For optimum bond strength and to insure maximum performance in the finished assembly mate parts together within the specified working time of the adhesive (7 - 8 Minutes).
- Make sure the bond joint has uniform coverage and that a sufficient amount of adhesive is in the bond area.
- It is important to have the adhesive applied, parts aligned and positioned, within the established work time for the product.
- To ensure maximum performance in the finished assembly parts should remain undisturbed until the joint is sufficiently cured.
- For the highest strength bonds surfaces should be clean, dry, and free of contamination.
- Extensive surface preparation is not required for AT-4020 and good bonds can be formed on most substrates after asolvent wipe.
- However we recommend that metal surfaces (particularly aluminum) be given a scotch brite cleaning to remove surface oxidation to achieve the highest bond strengths.
Properties
- Physical Properties of Cured Material
- Uncured Properties
- Effect of Temperature
- AT-4020 is best used at temperatures between 65° F and 80° F.
- Temperatures below 65° F will slow the cure speed of the material and theviscosities will be higher.
- Temperatures above 80° F will cause the material to cure faster and the viscosities will be lower.

Packaging & Availability
- Packaging Information
AT-4020 is conveniently packaged in 50 Ml cartridges.
Storage & Handling
- Shelf Life
- 12 months
- Storage Conditions
- Shelf life is based on the product being stored properly at a temperature no greater than 72°F.
- Exposure to temperatures above 72° F will reduce the shelf life ofthe product.
- While refrigeration isn’t necessary it will extend the shelf life of the product in hot climates.
- AT-4020 should never be frozen.
