Instructions for Use

Thoroughly mix Part A with Part B in a 1:1 mix ratio by weight or volume. Deviations from the

1:1 mix ratio may change cure rates. Airless mixing, metering and dispensing equipment are

recommended for production processing.

Deaeration

Remove air entrapped during mixing by common vacuum deaeration procedure, observing all

applicable safety precautions. Slowly apply vacuum, up to 28 inches Hg, to a container rated

for use and of volume at least four times that of material being deaerated. Hold vacuum until

presence of air is no longer evident.

Substrate Considerations

Cures in contact with most materials, exceptions include: butyl and chlorinated rubber, some RTV silicones and unreacted

residues of curing agents used with a few types of plastics.

Note:Some bonding applications may require the use of a primer. NuSil Technology LLC LS1-3200 silicone primer is

recommended.

NuSil LS-3351概述：
  
1、 LS-3351 A&B 1：1双组分硅胶
2、1.51折射率，95%以上高透光性，混合后粘度6000CPS 00055凝胶；
3、100度一小时固化；
4、耐温-40~200度，可通过260度回流焊1~2分钟

Instructions for Use

The product is supplied in ready-to-use cartridges that mix the material automatically as it is dispensed

without need for vacuum degassing.

Deaeration

The assembly should self-deaerate due to the product’s long room temperature work time and low

viscosity, as long as no pockets of air are trapped beneath mechanical parts. If accelerated deaeration is

required, the assembly may be vacuum deaerated using a pressure of 635 mmHg (25 inHg) or greater.

Apply the vacuum while observing the uncured fluid for presence of bubble formation and increase

vacuum slowly enough to avoid rapid foaming. Hold vacuum until bubbles at the fluid surface

collapse and are no longer visible.

Cure Inhibition

LS-3351 cures in contact with most properly cleaned substrate materials including optical glasses, optical plastics, and photonic

semiconductors. Adhesion to fluoroplastic substrates is generally poor but may be improved with chemical etching or plasma etching

of the substrate. Substrates to avoid include certain butyl, nitrile, chlorinated, and EPDM elastomers, certain plastics with leachable

plasticizers, and the cure residues of certain adhesives including UV-cured epoxies and amine-cured epoxies.
