SeamPro

SeamPro is a traditional solid surface adhesive that bonds acrylic and polyester. Also works with quartz, granite, marble, porcelain and sintered stone.

Overview

SeamPro 10:1 adhesive in 250ml cartridges usable in the 250ML dispensing gun.

Two tips are included.

Product Data

1. DESCRIPTION

SeamPro Adhesives are a two-part methacrylate, ultra violet light stable, non-yellowing surfacing adhesive designed for the seamless bonding of solid surface (acrylic and polyester and blends), engineered stone, and natural stone products. Combined at a ratio of 10:1 (10 parts resin, one part activator), SeamPro adhesives have a working time of 10 to 15 minutes and achieve nearly 90 percent of its ultimate strength in 25 to 30 minutes at room temperature curing. SeamPro adhesives offer a combination of high strength, stiffness, and toughness as well as the ability to bond very strongly to a wide variety of solid surface materials. SeamPro adhesives provide high strength bonds to acrylic solid surface, polyester solid surface (both filled and unfilled), and alloy solid surface (combinations of both acrylic and polyester solid surface resins). SeamPro adhesives give the fastest initial strength (green strength) and quickest routable time from dispensing of any of the contemporary adhesives in the market place. Take the SeamPro challenge and test it for yourself. SeamPro adhesives are the Professionals’ Choice When Seaming Countertops.

6. HANDLING AND APPLICATION:

SeamPro adhesive (Part A) and activator (Part B) are flammable. Contents include Methacrylate ester and acids, and peroxide. 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 SeamPro Material Safety Data Sheet for more complete safety instruction. 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. Sheet, adhesive, and shop temperature can have a significant effect on the work and fixture time of the adhesive. Application of SeamPro 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. SeamPro 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 SeamPro adhesives are affected by temperature.
NOTE: Because of the rapid curing features of SeamPro adhesives, large amounts of heat are generated when large masses of material are mixed at one time. The heat generated by the exothermic reaction 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 .125 inches.

7. HANDLING AND STORAGE

The shelf life of SeamPro is two (2) years from the date of manufacture based upon continuous storage at room temperature (77°F or 25°C). Storage of SeamPro in refrigerated compartments will extend the shelf life even more. Do not store SeamPro or any other adhesives in a refrigerator which has food or lunch products in them. Be sure to bring SeamPro 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 SeamPro 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. SeamPro adhesives contain no water, so freezing of the adhesive for short periods is permissible, but is not encouraged.
