Q: What are the forms of S-LEC?
⇓⇑
A: S-LEC is a powdered resin with good toughness, strong adhesion, and excellent dispersibility. S-LEC is non-toxic, odorless, colorless, and transparent. It can be dissolved in solvents or formed into films, thus it can be processed by various methods and applied in a wide range of fields.
Q: What are the forms of S-LEC?
⇓⇑
A: The standard form of S-LEC is a white powder, but it is also available in granular and liquid forms. The availability of different grades of S-LEC varies. Please contact our company for details.
Q: How to use S-LEC?
⇓⇑
A:The most common use is to dissolve S-LEC in organic solvents and mix it with various powders (such as inorganic powders and pigments). It can also be melted by heating. Through heating processes, S-LEC can be made into sheets or ued as a raw material for adhesives.
Q: Which solvents can S-LEC dissolve in?
⇓⇑
A: S-LEC is soluble in a variety of solvents, such as alcohols, esters, ketones, and aromatic solvents. The types of solvents that S-LEC can dissolve in vary depending on its grade.
Q: What are the benefits of using S-LEC?
⇓⇑
A: S-LEC improves coating toughness, enhances adhesion to other materials, and achieves uniform dispersion in solutions such as pastes and inks. Furthermore, it offers a variety of unique benefits that aid in product development.
Q: What products are S-LEC used in?
⇓⇑
A: S-LEC can be used as an interlayer film in laminated glass, a ceramic adhesive, and a printed circuit board adhesive, as well as in paints, inks, and many other products.
Q: How does S-LEC differ from other resins?
⇓⇑
A: The most distinctive feature of S-LEC is the simultaneous presence of both polar and non-polar groups in its resin. This unique structure allows for customized processing to meet specific customer application requirements.
Q: What is the specific impact of hydroxyl content on water resistance/chemical resistance?
⇓⇑
A: Higher hydroxyl content (e.g., S-LEC B BX-1, S-LEC B BX-L) results in stronger resin polarity, slightly increasing water sensitivity, but leading to stronger adhesion to polar substrates such as glass and metals. Grades with low hydroxyl content (such as S-LEC B BM-1, S-LEC B BM-5) exhibit stronger hydrophobicity, resulting in better water and chemical resistance.
Q: What are the storage and shelf-life requirements for S-LEC?
⇓⇑
A: S-LEC resin should be stored in a dry, cool, and well-ventilated place, avoiding direct sunlight and moisture. The packaging should be tightly sealed. Specific shelf-life details should be found in the property data sheet for the corresponding grade, but it can typically last for several years under proper storage conditions.
Q: Will S-LEC decompose or yellow at high temperatures?
⇓⇑
A: S-LEC has good thermal stability. However, during high-temperature processing (typically referring to sintering or extrusion), it is essential to ensure operation within the recommended temperature range. Its low combustion residue is a key advantage when used in adhesives requiring complete burnout, but prolonged exposure to extremely high temperatures before sintering should be avoided to prevent initial degradation.
