MXBON 41352 UV ADHESIVE

UV light and/or visible light

MXBON® 41352 can be cured by UV light and/or visible light. The range of wavelength are 365nm. To obtain full cure on surfaces exposed to air, radiation 220 to 260 nm is also required. Fixture time and cure speed achieved depend on substrate used, bonding gap, UV intensity, exposure time and spectrum distribution of light source.

Activator

MXBON® 41352 can be corresponded with MXBON® 037387. MXBON® 037387 is designed to initiate the cure process for MXBON® products. Fixture time and cure speed achieved depend on adhesive used, the substrate bonded. Applying activator to one surface and the adhesive to the other, mate and clamp.

Heating

MXBON® 41352 can be cured by Heating. Generally, it should consider the substrate which could sustain at high temperature.

UV light and/or visible light

Initially cured

The cured rate depends on substrates. Fixture time is defined as the time to develop the shear strength of 0.1 N/mm2 .

Initial time : 6 mW/cm2 @365nm, ≤ 12 second

30 mW/cm2 @365nm, ≤ 10 second

100 mW/cm2 @365nm, ≤ 6 second

Tack free time :100 mW/cm2 @365nm, ≤ 15 second

Deep (1-3 mm) Fixture time : 100 mW/cm2 @365nm, < 60 second

Fully cured

The cured rate depends on glue amount 、glue layer thickness (gap/depth) and light intensity (energy). It is between a few seconds to 30 seconds.

Deeply cured

The cured rate depends on the type of light source、the wavelength range of the light radiated、light intensity energy and lighting time. The figure shows that MXBON® 41352 apply to different light intensity, glue layer thickness and cured speed.

Activator

Initially cured

The cured rate depends on substrates. Fixture time develop a shear strength of 0.1 N/mm2

Initial time: 2 to 6 minutes.

Fully cured

The cured rate depends on glue amount 、glue layer thickness (gap/depth) and substrates. Full strength will be achieved after 72 hours.

Heating

Heating temp. (°C)	Heating time (minutes)
80 to 100	90 to 120
100 to 120	50 to 90
Over 120	30 to 50

Cured speed and glue layer thickness

The cured rate depends on glue amount、glue layer thickness (gap). The thinner adhesive layer has a faster curing rate and bonding strength. On the contrary, the large gap has a slower curing rate and lower bonding strength.

Cured speed and substrates

The cured rate depends on substrates. MXBON® 41352 has not suitable for soft materials, such as: rubber and silicone.

This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be use with chlorine or other strong oxidizing materials. Where washing systems are used to clean the surfaces before bonding, it is important to check the compatibility of the washing solution with the adhesive. In some cases, these solutions can affect the cure and performance of the adhesive. Users are recommended to confirm compatibility of the product with such substrates.

Keep adhesive in a cool and dry place. The storage temperature is recommended at 8 °C to 21 °C. For details, consult the Safety Data Sheet, (SDS). Shelf life is one years from the date of manufacture in the original container under the optimal conditions.

1. Avoid contact with skin and eyes.

2. If contact with skin, rinse with water.

3. If adhesive gets into eye, keep eye open and rinse with water thoroughly. Seek medical attention immediately.

4. Keep the material out of children’s reach.
