Applications & Uses

Application Instructions

General Instructions

The product is best used at temperatures between 65°F and 80°F.
Temperatures below 65°F will slow the cure speed of the material and viscosities will be higher.
Temperatures above 80°F will cause the material to cure faster and viscosities will be lower.
For consistent dispensing maintain temperature in the above mentioned range.
For optimum bond strength and to insure maximum performance in the finished assembly mate parts together within the specified work time of the adhesive.
Make sure the bond joint has uniform coverage and that a sufficient amount of adhesive is in the bond area.
It is important to have the adhesive applied, parts aligned and positioned, within the established work times for the product.
To ensure maximum performance in the finished assembly parts should remain undisturbed until the fixture time is reached.
