DAI MMA 4000 Acrylic - Crystal Clear Medium Set 18-Min MMA Adhesive-Low Viscosity & UV Stable Resistant-10:1 ratio
MMA 4000 is a two-part 10:1 ratio methacrylate (MMA) adhesive suitable for solid surface seaming application. It contains a unique crystal clear/water clear feature and lower viscosity, whereas most other MMAs are thicker.
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 resistance to water, impact, wear, scuffing, boiling water, high temperature and UV light. The product is translucent-clear, UV stable and non- yellowing.
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.

Directions of applications
Wipe off the surface to be bonded, de-greasing or de-oiling is optional, unless excessive grease or oil is present. The product can be applied using a manual dispenser or pneumatic dispenser. Make sure to mate the surfaces to be bonded before the work time. The nozzle sizes can be selected according to the desired thickness. Use the gloves to avoid skin contact. Join the substrates within 8 minutes and allow it to cure at room temperature. Do not disturb the parts during the curing process. Excess adhesive can be wiped off.
Safety and handling
Wear safety glasses and gloves. Harmful if swallowed. Keep the material away from heat, and flames. Keep out of reach of children. Once used keep the containers closed.
Storage and shelf life
Store this product in a tightly closed container in a cool and well-ventilated area. Product should not be frozen. Keep it away from any source of heat. Store the material in between 51℉ to 75℉. Continuous exposure above 75℃ will reduce the shelf life. Shelf life of the material is 10 months, if the storage conditions are followed.
