Gainsboro Multibond 250 ML Cartridge
Multibond 250 ML cartridge seam adhesive for porcelain, engineered stone, marble, quartz, and natural stone.
About Multibond GB309 Gainsboro:
Multibond adhesives are a two-part methacrylate, super flexible, dripless/non-sag, low shrink, low exotherm, ultra violet light stable, non-yellowing hard surfacing adhesive designed for the nearly seamless bonding of porcelain, sintered stone, glass, engineered stone, marble and quartz, and 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 the propriety an adhesion promoter surface cleaner/activator, Multibond Gainsboro provides high strength bonds to virtually any stone, engineered stone, quartz and granite products, including porcelain, sintered stone, and glass.
Using an adhesion promoter with Gainsboro-GB309 glue, stone fabricators can bond successfully to wet stone, although bonding underwater is not permitted or recommended. Multibond adjesives give fabricators the opportunity to apply adhesive to vertical surfaces as well as horizontal surfaces, without dripping. When they gel, these glues give the fabricator an extended window (5-10 minutes) to de-rope, or trim with a single bladed straight edge razor blade. The excess from the stone slab can be removed without ripping the adhesive out of the joint, nor damaging the surface of the stone.
Additionally, since Gainsboro GB309 glue is supplied in cartridges, unlike other cartridge adhesives in the market, wherein the resin (large side) is pigmented, with Multibond, the activator (small side) is pigmented. For the fabricator, this means that when he sees color, he knows that the product is catalyzed, and will get dry/react/get hard 100% of the time. Sold exclusively at Tenax USA.

Directions for Use:
To assure maximum bond strength, please follow these practices to get the best performance from Multibond adhesives:
- Surfaces must be mated together within the specified working time.
- All clamps affixed within the working time.
- Use a sufficient amount of glue to completely fill the joint when parts are mated and clamped.
- Avoid over clamping parts which can cause a dry joint or a joint starved of adhesive.
- All application of Multibond Gainsboro GB309, part positioning, fixturing, and clamping should occur before the working time of the glue has expired.
- After the indicated working time, parts must remain undisturbed until the fixture time is completed.
- Sheet, adhesive, and shop temperature 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.
