Other Fabrication Tips

Some typical tack times are listed below.

The quality of a bond depends largely on the careful preparation of the surface to be joined and the bonding techniques utilized. Tack time varies with the substrate being used.

Tack time here is defined as the amount of time it takes before a butt joint, 6 inches in length, can be picked up by the bonded end and will not separate itself from the surface of the other piece. In general, particularly for thinner materials, tack times are longer for ACRYLITE® cast and ACRYLITE® Resist sheet when using this cement compared to other commercial solvent cement on the market. ACRIFIX® 1S 0117 cement has similar tack times for ACRYLITE® Resist sheet.

The table below provides helpful hints on how to get the best possible bonds.

ACRYLITE® premium, ACRYLITE® cast, and ACRYLITE® Resist sheet each behaves differently when used with this cement; therefore, application, instructions are slightly different for each.

Bonding Technique

Fix the parts to be bonded in the desired position. Introduce ACRIFIX® 1S 0117 into the joint either from a glue dispenser or disposable syringe, and avoid bubble formation. It can be used for making T-joints and bonding narrow areas of ACRYLITE® premium, ACRYLITE® Resist, and ACRYLITE® cast sheet. It can be utilized in the same applications as dichloromethane based cement as long as proper precautions are observed. It will not fill gaps caused by unfinished edges. It is recommended that edges be either scraped or milled to produce a flat level cementing surface. The technique is always an issue, but in general, bubble-free joints are more readily obtained using this cement than other commercial solvent cement due to the fact that it is less viscous and flows better upon application. The resulting bond will be firm in a relatively short period of time depending on the substrate and will have high ultimate strength.

NOTE: For best results, work on a flat and level surface. ACRYLITE® premium, ACRYLITE® Resist, and ACRYLITE® cast sheet each behave differently when used with this cement; therefore, application instructions are slightly different for each:

ACRYLITE® premium sheet: Best results are achieved by using the shim sizes and shim removal times as recommended. When removing the shims, be careful not to take them out too abruptly. Due to the fact that the tack time is slow, it is possible to move the part with the slightest force. After 1.5 to 2 minutes from the time of application of cement, apply a pressure of 1.0 to 2.0 psi for 2 to 3 minutes. To obtain greater strength, apply a weight of 1.0 to 2.0 pounds per square inch of bonded surface area for 30 to 45 minutes for a sheet of thickness less than 0.236”. Apply the weight for 15 to 30 minutes for sheet thickness greater than 0.236”. The finished piece can be further processed after 2.5 to 3.5 hours and will increase in bond strength over the next few weeks.

ACRYLITE® Resist sheet: Utilize the capillary method with 0.004” shims for sheet thickness greater than or equal to 0.236", and 0.002” shims for sheet less than 0.236” in thickness. Remove shims within a few seconds after the application of cement. Apply a weight of 1.2 to 2.0 pounds per square inch of bonded surface area for 15 to 30 minutes which will ensure greater ultimate adhesion. The piece can be processed after 2 to 3 hours and will increase in bond strength over the next few weeks.

ACRYLITE® cast sheet: It is recommended shims not be used with ACRYLITE® cast sheet. Only use shims if there is difficulty in getting cement into the joint. In order to keep ACRYLITE® cast sheet from moving, especially for thinner materials, a jig should be used to support the sheet. After 3 to 5 minutes from the time of application of cement, apply a pressure of 1.5 to 2.5 psi for 2 to 3 minutes. To achieve higher strength, apply a weight of 1.0 to 2.0 pounds per square inch of bonded surface area for 45 to 60 minutes for sheet thickness less than 0.236”. Apply the weight for 30 to 45 minutes for sheet thickness greater than 0.236”. The finished piece can be further processed after 3 to 4 hours and will increase in bond strength over the next few weeks.

Annealing

Crazing will occur if high internal stress from fabrication is not relieved. Internal stress can be minimized by careful fabrication and annealing before the cementing. To anneal ACRYLITE® sheet, place it in an air circulating oven at 180°F for an hour for each millimeter of a thickness (minimum of two hours). For example, a 6.0 mm (0.236”) sheet would be annealed for six hours.

Safety Measures and Health Protection

Irritating to eyes, respiratory system, and skin. Sensitization by skin contact possible. Keep away from any source of ignition. Wear suitable protective gloves to avoid contact with skin. Avoid eye contact. In operations where eye or face contact could occur, wear eye protection such as chemical splash-proof goggles or a face shield. In the event of contact with eyes, rinse immediately with plenty of water, and consult a doctor.

Contains flammable liquid and vapor which can be harmful if inhaled. Keep away from heat, sparks, and flame. Avoid breathing vapor. Keep the container closed. Use adequate ventilation.
