Multibond 250 ML Glue Cartridge GB302 Natural Spring
Multibond 250 ML Natural Spring GB302 cartridge seam adhesive for porcelain, engineered stone, marble, quartz, and natural stone.
About Multibond Adhesive - GB302 Natural Spring:
Multibond adhesives are a two-part methacrylate with the following characteristics:
- Super flexibility
- Dripless, Non-sag Consistency
- Low Shrink
- Low Exotherm
- Ultra Violet Light Stability
Multibond is a hard surfacing adhesive designed for the nearly seamless bonding of the following materials:
- Sintered Stone
- Engineered Stone
- Natural Stone Products
Combined at a ratio of 10:1 (10 parts resin, one part activator), Multibond adhesives have a working time of 10-15 minutes, with a 5 to 10 minute de-roping time, and achieve nearly 90% of its ultimate strength, stiffness, and toughness as well as the ability to bond very strongly to a wide variety of hard surface or inorganic materials.
When combined with the proper use of an adhesion promoter surface cleaner/activator, Multibond adhesives provide high strength bonds to virtually any stone, engineered stone, quartz and granite products, including porcelain, sintered stone, and glass.
With the use of an adhesion promoter, stone fabricators can bond successfully to wet stone, although bonding underwater is not permitted or recommended. Multibond adhesives permit fabricators the opportunity to apply the adhesive to vertical surfaces, as well as horizontal surfaces. There is no dripping and upon gelation.
Multibond glue gives the fabricator an extended window (5-10 minutes) to de-rope. The finished seam is clean because trimming the excess glue is easier. Using a single bladed straight edge razor blade to remove the excess can be done without ripping the adhesive out of the joint or damaging the surface of the stone.
Additionally, since the product is supplied in cartridges the fabricator can more easily work with the glue. Other cartridge adhesives in the market pigment the resin (large side). Multibond takes a different approach by pigmenting the activator (small side). This means that when the fabricator sees color he knows that the product is catalyzed. Thus yielding a 100% drying/reaction/hardening rate.
Directions for Use:
To assure maximum bond strength the following practices should be carefully implemented:
- Surfaces must be mated together within the specified working time
- All clamps need to be affixed within the working time.
- Use sufficient glue 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.
- 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.
- temperature of the sheet, the adhesive, and the shop can have a significant effect on the work and fixture time of the adhesive.
Application of Multibond 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. Multibond 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 pull a tight seam. The viscosities of Multibond adhesives are affected by temperature.
The shelf life of Multibond is one 1 year from the date of manufacture based upon continuous storage at room temperature (77°F or 25°C). Storage of Multibond in refrigerated compartments will extend the shelf life even more.
Do not store Multibond or any other adhesives in a refrigerator which contains food or lunch products.
Be sure to bring Multibond 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 Multibond adhesives, especially the activity of the catalyst.
Storage at temperatures above 100°F or 38°C could shorten the shelf life to less than one month. Multibond adhesives contain no water, so freezing of the adhesive for short periods is permissible, but is not encouraged.
