HXTAL NYL-1 Epoxy Adhesive 1.3 ounce Kit

HXTAL NYL-1 is a museum quality epoxy adhesive for laminating, bonding, and repairing glass. It is a water white (optically clear) adhesive with the same index of refraction as borosilicate glass. HXTAL is extremely versatile and can be thinned down for use as a clear coat or allowed to thicken in order to mold into missing parts of glass. With a long history and excellent track record it is one of the best adhesives for bonding glass to glass and glass to other mediums. The 1.3 ounce kit contains 1 ounce of Part A and 0.33 ounce of Part B in convenient glass pipet bottles for easy mixing of smaller amounts.

Customer Questions
Is there a good release agent for HXTL? Vaseline?

I haven't used Vasoline before but it should probably work. I have used standard mold release spray before and it has worked well as a release for HXTAL.

Approximately how many square inches of surface area of glass will a 1.3 ounce kit bond together?

Roughly a 6 inch x 6 inch area. The smaller kits are meant more for small jobs like jewelry work and crack repair.

Hello, can you bond heat-treated glass

Yes, you can certainly bond tempered glass. 

What is the shelf life of unopened bottles?

HXTAL doesn't really have a shelf life. We've had customers using the same batch for over 8 years.
