EPOTEK353ND epoxy resin curing adhesive from the United States

353NDUsage Guidelines

The usage process of 353ND fiber optic adhesive provided by EPOXY TECHNOLOGY ING in the United States is as follows:

1．Storage of 353ND

353ND Part A&B requires storage at room temperature without refrigeration when not mixed. If it is stored below 0 ℃,

So before mixing A&B, it is necessary to lower the temperature at room temperature for at least 3-4 hours. This process is to avoid the production of water in Epoxy

Generate moisture to prevent the formation of bubbles during material solidification.

2.353ND Part A&B Mixing Process

＊ If 353ND Part A&B is packaged in a 4-gram A-Pack plastic bag, the A&B components have been proportionally distributed and packaged. Simply mix them in the following steps to apply:

A. Remove the core shaft and apply pressure from the end of component A to allow the resin to move towards the sealing point of component B.

B. Apply force to squeeze the resin so that it can break through the separable barriers.

C. Then fix the end of the plastic bag and run the resin from beginning to end until component A and component B are completely mixed.

D. Cut open the end of the plastic bag and squeeze out the already mixed 353ND for application.

＊ If the packaging of 353ND Part A&B is for large quantities (such as iron cans, plastic bottles, or glass bottles, etc.), the first step is to include component A and

After shaking the B components evenly, mix them evenly in a glass container in a ratio of 10 parts of Part A and 1 part of Part B.

If a large number of bubbles are found to be generated after mixing, a defoaming process should be carried out before application. The defoaming methods include vacuum defoaming and ionization

There are two types of heartbeats.

3.353ND can be used for pot life and dosage after mixing

The usable time after mixing 353ND is 4 hours, so the usage should be controlled to achieve the technical performance indicators of the resin

best. Because after mixing, if the viscosity of all epoxy resins exceeds their usable time, it will change and affect their adhesion

Adhesive force. Epoxy Technology Inc. recommends that the recommended dosage per use should not exceed 25 grams.

4.Curing Time

Epoxy Technology Inc. provides the following data on curing time and temperature for users' reference

60 ℃ for 1.5 hours

80 ℃ for 15 minutes

100 ℃ for 5 minutes

120 ℃ for 2 minutes

150 ℃ for 1 minute

The curing condition of 353ND starts at 150 ℃ or 200 ℃ for the first 10 seconds, so the additional curing temperature provided in the above column is

Time is for reference only, and it also generates some heat during curing. Under normal circumstances, it is not recommended to operate at 150 ℃

The above temperature should be used for curing, preferably at 150 ℃ for 1 minute or at 80 ℃ for 15 minutes. But the actual solidification

The time should be based on the curing reaction of the test product to 353ND.
