DAI MMA 4025 Acrylic - Medium Set 30- 40 Min Toughened Impact Resistant MMA Adhesive-High Viscosity Blue-10:1 ratio
DAI MMA 4025 is a medium set time medium-viscosity, toughened non-sagging non-dripping two-part 10:1 ratio methacrylate (MMA) adhesive suitable for solid surface seaming application. Because it's toughened, it's highly shock resistant, and can preserve it's bond strength against impacts and other striking forces.
It offers excellent adhesion to a variety of solid surface sheet materials, including acrylics, cast acrylics, polyesters, cast/densified polyesters, thermoplastics and composites. It exhibits a high impact strength and toughness and is recommended for bonding applications in marine industries. The product cures to a light blue color.
Please Note: These cartridges are designed to work best with a 50ml, 250ml or 490ml 10:1 ratio cartridge Dispenser. We advise you use a 50ml, 250ml or 490ml Dispenser for all respective cartridges. If you do not have one, please check out our Dispensers, all are excellent products and have our 'it's good' seal of approval.
If you prefer not to use a Dispenser, we have some 50ml kits that include hand tools, as pictured, that you can use for fast small jobs. But the 250ml and 490ml cartridges really need to use the correct-sized Dispenser, they're just too big to effectively use without the dispenser.
