It mixes at a 1:1 ratio, has a 3 to 6 minute working time, reaches handling strength in 10 to 15 minutes, and provides lap shear strength of 3,000+ psi with 20 to 30% elongation for tough, slightly flexible bonds.\u003c\/p\u003e\n\u003cp\u003eUltraLok 300 is the 5 minute, rubber-toughened workhorse of the UltraLok acrylic family.

UltraLok 300 bonds most substrates with little or no preparation. Dispense through a static mixing nozzle, apply to one surface, join the parts, and hold or fixture until set. Note that UltraLok 300 is not UV stable and will yellow over time. Yellowing does not affect bond performance.\u003c\/p\u003e\n\u003ch2\u003eOrdering and Support\u003c\/h2\u003e\n\u003cp\u003eNot sure which UltraLok working time or size fits your job?
