Product Description
Extreme SeamWelder (Solid Surface Seaming Adhesive) series of methacrylate structural adhesives offers a unique combination of strength and clarity for use where transparency is needed or where color matching is required. This cure system forms hard, clear bonds to Acrylic sheeting, solid surface materials, composites, and certain woods. A UV stabilizer has been added to the system to prevent yellowing or color change due to sunlight of aging effects. The hardness of the cured material allows for sanding within an hour without loading. Sections up to .125” thick remain clear with no inherent color tint at the edges.
Although it is always best to clean and prepare most bonded surfaces for improved adhesion. Extreme SeamWelder will work successfully in many applications without preparation.
Extreme SeamWelder is moderate cure speed, two-component product with an open time of 10-12 minutes at 23º C after thorough mixing.
The product is supplied in pre-measured cartridges of 250ml. for controlled application.
