- Applications
To assure maximum bond strength, surfaces must be mated together within the specified working time, and all clamps affixed within that time. Use sufficient material to ensure that the joint is completely filled when parts are mated and clamped. Avoid over clamping parts, which may cause a dry joint or a joint starved of adhesive. All adhesive application, part positioning, fixturing, and clamping should occur before the working time of the adhesive has expired. After the indicated working time, parts must remain undisturbed until the fixture time is completed. Components bonded, adhesive, and shop temperature can have a significant effect on the work and fixture time of the adhesive. Application of SeamLock adhesive at temperatures between 65°F and 85°F (18°C and 30°C) will ensure proper cure. Temperatures below 65°F (18°C) will slow cure and fixture speed. SeamLock adhesives will still react, but will take longer. Temperatures above 85°F (18°C and 30°C) will increase cure and fixture speeds, and there’s a risk that the adhesive will be hardened or too thick to bond materials. The viscosities of SeamLock adhesives are affected by temperature.
Note : Because of the curing features of SeamLock adhesives, large amounts of heat are generated when large masses of material are mixed at one time. The heat generated by the exotherm resulting from mixing large amounts of adhesive can result in a boiling of the monomer in the adhesive (methyl methacrylate), resulting in the release of trapped air, steam and volatile gasses. To prevent this, use only enough material as needed for use within the working time for the product, and confine the gap or spread out the material to no more than .50 inches.

Safety & Health
- Safety & Health Precautions
SeamLock resin (Part A) and activator (Part B) are flammable. Contents include Methacrylate ester and acids. Keep containers closed after use. Wear gloves and safety glasses to avoid skin and eye contact. Wash with soap and water after skin contact. In case of eye contact, flush with water for 15 minutes and get medical attention. Harmful if swallowed. Keep out of the reach of children. Keep away from heat, sparks, and open flames. Do not smoke cigarettes or anything else while handling or near the product. Refer to the SeamLock Safety Data Sheet for more complete safety instruction.
Storage & Handling
- Shelf Life
- 12 Months
- Storage, Handling and Shelf Life
The shelf life of SeamLock is twelve (12) months from the date of manufacture based upon continuous storage at room temperature (77°F or 25°C). Storage of SeamLock adhesives in refrigerated compartments will extend the shelf life even more. Do not store SeamLock adhesive or any other adhesives in a refrigerator which has food or lunch products in them. Be sure to bring SeamLock adhesives to room temperature for 24 hours before use, otherwise longer cure and fixture times may be expected. Long-term storage at temperatures above room temperature will shorten the shelf life of SeamLock adhesives considerably. Storage at temperatures above 100°F or 38°C could shorten the shelf life to less than one month. SeamLock adhesives contain no water, so freezing of the adhesive for short periods is permissible, but is not encouraged.
