Applications & Uses
- Compatible Substrates & Surfaces
- Cleaning Information
- Adhesive components and mixed adhesive should beremoved from surfaces with a suitable industrialsolvent or cleaner before the mixed adhesive cures.
- Once the adhesive cures, soaking in a strong solventor paint remover will be required to soften theadhesive for removal.
- Any clean-up of the bondedassembly using industrial solvents is notrecommended as it could affect the cure.
- Surface Preparation
- The need for surface preparation must be determined bycomparative testing of prepared and unprepared substratesto assure that unprepared bonding is equivalent to oracceptable for the application relative to prepared bonding.
- Initial bonding tests must be followed up with simulated oractual durability tests to assure that surface conditions do not lead to degradation of the bond over time under service conditions.
- Subsequent changes in substrates or bonding conditions will require re-testing.
- Prepare metals forbonding by removing dust, loose scale, rust, and other surface residue including oil and grease.
- For maximum bond strength on steel, abrade surface prior to bonding.
- Substrate Suitability
- The user must determine the suitability of a selectedadhesive for a given substrate and application.
- Associated Technologies strongly recommends laboratory, shop andend-use testing that simulates the actual manufacturingand end-use environment.
- Most thermoplastics can bebonded with no surface preparation other than a dry wipeor air blow-off.
- If contamination is visible or suspected,wipe with alcohol prior to bonding. Polyolefins,thermoplastic polyesters, fluorocarbon plastics and otherlow surface energy plastics are generally not bondable.
- Testing is required on thermoset plastics because of thewide variations in compositions
- Curing
- Open working time is the approximate time after mixing components A and B, depending on bonding conditions, that the adhesive remains fluid andbondable.
- Fixture time is the approximate time aftermixing components A and B required for the adhesiveto react the partial state of cure necessary to allowcareful movement, unclamping or de-molding of assembled parts.
- Parts can generally be put in servicewhen 80 percent of full strength is developed.
- The time to achieve 80% cure is approximately 2-3 times thatrequired for fixturing.
- The working and fixture timespresented in this bulletin are based on laboratory tests performed at 75°F/24°C.
- Higher temperatures speedthe curing reaction and reduce open working time.
- Mixing and Application
- EXOTHERM: The chemical curing reaction that occurswhen components A and B are mixed generates heat.
- The amount of heat generated is controlled by themass and thickness of the mixed product.
- Large masses over 1/2 inch thick can develop heat in excessof 250°F/121°C and can generate harmful, flammablevapors.
- Large curing masses should be carefully moved to a well-ventilated area where the chance ofpersonal contact is minimized.
Properties
- Physical Properties of Cured Material
- Uncured Properties
- Effect of Temperature
- AT-6030 is best used at temperatures between 65° F and 80° F.
- Temperature below 65° F will slow the cure speed of the material and the viscosities will be higher.
- Temperatures above 80° F will cause the material tocure faster and the viscosities will be lower.
- For consistent dispensing maintain temperature as listed above.

AT-6030 is conveniently packaged in 40 Ml cartridges.
Storage & Handling
- Shelf Life
- 6 months
- Storage Conditions
- The shelf life of components A and B in unopened containers is approximately six months from the date the product is shipped from
- Associated Technologies facility. Shelf life is based on steady state storage between 55°F and 80°F (13°C and 27°C).
- Exposure, intermittent or prolonged, above 80°F (27°C) will result in a reduction of the stated shelf life.
- Exposures above 100 ºF (38 ºC) during shipping or storage can quickly degrade component B in cartridges or bulk containers, and must be prevented.
- Shelf life of both components can be extended by air-conditioned or refrigerated storage between 50°F and 65°F (10°C and 18°C).
- Keep from freezing.
